RESUMEN
Purpose: To validate a new methodology to evaluate the impact of astigmatism in pseudophakia using an astigmatic defocus curve. Setting: Hospital Oftalmológico de Brasilia, Brazil. Design: Non-randomized cohort study. Methods: For every point of the defocus curve, from -2.00 to +3.00 with 0.50D intervals, visual acuity was assessed with optically induced astigmatism (0.50D, 1.00D and 1.50D at 90 and 180 degrees) in pseudophakic patients implanted with a refractive-enhanced intraocular lens. Results: Twelve patients were analyzed. A statistically significant difference was found between the 90° (ATR) and 180°(WTR) axis with 1.50D astigmatism, providing better visual acuity in ATR astigmatism (p < 0.05). Conclusion: This new methodology is reproducible, useful and may predict residual astigmatism tolerance in pseudophakic patients, which may help with surgery planning and IOL decision-making.
RESUMEN
Purpose: To analyze whether femtosecond laser-assisted surgery leads to less cumulative dissipated energy (CDE) and decreased endothelial cell loss compared to conventional surgery. Patients and Methods: This non-blinded, non-randomized, quasi-experimental clinical trial was conducted at one center and involved one surgeon. Patients with cataracts and 50-80 years old were included, and the exclusion criteria were radial keratotomy, trabeculectomy, drain tube implant, corneal transplant, posterior vitrectomy, and re-implantation of intraocular lens. In total, 298 patients were recruited between October 2020 and April 2021, and the data collected included sex, laterality, age, ocular comorbidities, systemic comorbidities and CDE. An endothelial cell count was performed before and after surgery. Patients were divided according to femtosecond laser-assisted phacoemulsification or conventional phacoemulsification. The femtolaser patients were submitted to the equipment, and then, immediately after treatment, phacoemulsification surgery was performed. In the conventional method, the "divide and conquer" technique was used. The statistical analysis was made using an analysis of covariance linear model, using SAS version 9.4 (SAS Institute, Inc., 1999). Values with p < 0.05 were considered significant. Results: A total of 132 patients were analyzed. The only statistically relevant predictors of CDE were the severity of the cataract (p < 0.0001) and age of ≥75 years (p = 0.0003). The following factors were not significant: technique with or without laser (p = 0.6862), sex (p = 0.8897), systemic arterial hypertension (p = 0.1658), and diabetes (p = 0.9017). Grade 4 cataracts were associated with higher CDE than grade 3 cataracts, which in turn were associated with higher CDE than grade 2 cataracts. A comparison of pre- and post-operative specular microscopy with and without laser revealed no significant discrepancy (p = 0.5017). Conclusion: Femtosecond laser-assisted cataract surgery did not reduce CDE or endothelial cell loss compared to conventional surgery regardless of severity.
RESUMEN
PURPOSE: To evaluate reliability and global indices parameters from standard automated perimetry (SAP) in normal eyes undergoing phacoemulsification cataract surgery with implantation of trifocal or extended depth of focus intraocular lens (IOL). METHODS: Prospective study to evaluate the effect of trifocal IOL AcrySof IQ PanOptix® and extended depth of focus intraocular lens (EDOF) Tecnis Symfony® IOL implantation on visual field parameters. Patients underwent SAP pre- and postoperatively. Reliability indices (false negative rate-FN, false positive rate-FP), global indices (foveal sensitivity threshold, visual field index-VFI, standard pattern deviation-PSD, mean deviation MD) and test duration were analyzed. RESULTS: A total of 23 eyes from 13 patients were in the trifocal IOL group and a total of 22 eyes from 14 patients were in the EDOF group. The following results were obtained by analyzing pre- and postoperative SAP of EDOF IOL: the rate of change of FN was 1.95/1.41% (p = 0.61); FP 1.64/1.27 (p = 0.60); MD - 1.60/- 1.08 dB (p = 0.15); foveal sensitivity was 34.5/33.9 dB (p = 0.41); VFI 98.5/98.4% (p > 0.99); PSD 1.85/1.86 (p = 0.07); and for test duration 305.81/298.36 s (p = 0.35); all respectively. Analysis of pre- and postoperative parameters of trifocal IOL were the rates of change of FN 1.22/1.83% (p = 0.29); FP 1.65/1.48% (p = 0.95); MD - 1.55/- 1.37 dB (p = 0.19); foveal sensitivity 33.9/34.9 dB (p = 0.47); VFI 98.6/98.3% (p = 0.62); PSD 1.58/2.05 (p = 0.02); and test duration 297.17/298.57 s (p = 0.87); all respectively. CONCLUSION: We identified a change in the PSD parameters in the trifocal IOL group. No other significant changes were identified in SAP parameters after implantation of trifocal AcrySof IQ PanOptix® and EDOF Tecnis Symfony® IOL. Longitudinal evaluation showed no changes in SAP after Trifocal and EDOF IOL implantation in normal subjects.

ABSTRACT Purpose: To compare the postoperative refractive predictability of IOLMaster 500 and Pentacam HR on the basis of keratometry and anterior chamber depth values in eyes with an indication for multifocal intraocular lens (IOL) implantation. Methods: This was a retrospective study conducted on 118 eyes treated with phacoemulsification and multifocal intraocular lens implantation. Only the eyes that achieved emmetropia in the dynamic refraction performed on postoperative day 30 were included. Haigis' formula was used in each case to calculate the intraocular lens power, and the intraocular lens with the target refraction closest to emmetropia was implanted. Four lens calculation scenarios were tested by combining keratometry and anterior chamber depth measurements obtained using the two devices. Results: IOLMaster 500 and Pentacam HR differed with regard to mean keratometry (D 0.07 ± 0.03 D; p=0.0065) and anterior chamber depth (D 0.08 ± 0.01 mm; p<0.001). In the analysis of covariance, the following differences were obtained using the Haigis' formula when confronted with the biometric values obtained by inserting keratometry and anterior chamber depth values, respectively: Penta/IOL x IOL/Penta (0.13 ± 0.03; p<0.0001); Penta/Penta × IOL/Penta (0.13 ± 0.03; p<0.0001); Penta/IOL × IOL/IOL (0.11 ± 0.03; p=0.001); Penta/Penta × IOL/IOL (0.11 ± 0.03; p=0.002); IOL/IOL × IOL/Penta (0.02 ± 0.03; p=0.865); and Penta/IOL × Penta/Penta (0.002 ± 0.03; p=0.99). The difference was smaller when measuring the anterior chamber depth using the IOLMaster 500, regardless of which device was used to measure keratometry. Conclusions: Pentacam HR significantly differed from IOLMaster 500 when calculating keratometry. As regards the anterior chamber depth, the two devices were equally accurate.
RESUMO Objetivo: Comparar a previsibilidade refrativa pós-operatória do IOLMaster 500 e Pentacam HR com base nos valores de ceratometria e profundidade de câmara anterior nos olhos com indicação de implante de lentes intraoculares multifocais. Métodos: Estudo retrospectivo realizado em 118 olhos tratados com facoemulsificação e implante de lentes intraoculares multifocal. Apenas os olhos que atingiram a emetropia na refração dinâmica no 30º dia pós-operatório foram incluídos. A fórmula de Haigis foi usada em cada caso para calcular o poder das lentes intraoculares, e a lente intraocular com a refração alvo mais próxima da emetropia foi implantada. Cenários de cálculo de quatro lentes foram testados pela combinação de medidas de ceratometria e profundidade de câmara anterior obtidas usando os dois dispositivos. Resultados: IOLMaster 500 e Pentacam HR diferiram quanto à média de ceratometria (D 0,07 ± 0,03 D; p=0,0065) e profundidade de câmara anterior (D 0,08 ± 0,01 mm; p<0,001). Na análise da covariância, as seguintes diferenças foram obtidas usando a fórmula de Haigis quando confrontadas com os valores biométricos obtidos pela inserção dos valores de ceratometria e profundidade de câmara anterior, respectivamente: Penta/IOL x IOL/Penta (0,13 ± 0,03; p<0,0001); Penta/Penta x IOL/Penta (0,13 ± 0,03; p<0,0001); Penta/IOL x IOL/IOL (0,11 ± 0,03; p=0,001); Penta/Penta x IOL/IOL (0,11 ± 0,03; p=0,002); IOL/IOL x IOL/Penta (0,02 ± 0,03; p=0,865); Penta/IOL x Penta/Penta (0,002 ± 0,03; p=0,99). A diferença foi menor ao medir a profundidade da câmara anterior usando o IOLMaster 500, independentemente de qual dispositivo foi usado para medir a ceratometria. Conclusões: O Pentacam HR diferiu significativamente do IOLMaster 500 no cálculo de ceratometria. Quanto à profundidade da câmara anterior, os dois dispositivos foram igualmente precisos.

PURPOSE: To assess the clinical outcomes after implantation of a new 340-degree arc length intrastromal corneal ring segment (ICRS) aided by the femtosecond laser in postkeratoplasty patients after a 12-month follow-up. SETTING: Private practice, Brasilia, Brazil. DESIGN: Prospective case series. METHODS: Eyes with previous keratoplasty had ICRS implantation assisted by femtosecond laser. The primary outcome measure was the change in the uncorrected distance visual acuity (UDVA) 12 months postoperatively. The secondary outcome measures were the corrected distance visual acuity (CDVA), refraction, and corneal tomography 1, 3, 6, and 12 months postoperatively. The astigmatism results were analyzed using vector analysis through the double-angle polar plot. RESULTS: Of the 18 patients, 7 (38.9%) were men, and 11 (61.1%) were women. The mean UDVA was 20/250 (1.15 logarithm of the minimum angle of resolution [logMAR]) before implantation and 20/70 (0.54 logMAR) at the last follow-up (P < .001). The mean CDVA improved from 20/35 (0.26 logMAR) to 20/25 (0.10 logMAR) (P < .001). The mean spherical equivalent and astigmatism components were significantly reduced after ICRS implantation. The mean corneal astigmatism decreased from 5.55 ± 2.29 D preoperatively to 3.92 ± 1.82 D postoperatively (P < .001). The CDVA remained the same or improved in 19 of 20 eyes and decreased by 1 line in 1 patient. There were no surgical complications. CONCLUSION: A new ICRS with a 340-degree arc length was effective in treating postkeratoplasty eyes, improving visual acuity and reducing corneal astigmatism.

PURPOSE: The aim of this study was to compare the visual outcomes and subjective visual quality between bilateral implantation of an extended depth of focus intraocular lens, J&J Vision Tecnis Symfony® ZXR00 (Group A) and bilateral implantation of a diffractive trifocal intraocular lens, Alcon Acrysof IQ PanOptix® TNFT00 (Group B). METHODS: This prospective, nonrandomized, comparative study of consecutive cases assessed 52 eyes of 26 patients operated on by the same surgeon (WTH) and binocularly implanted with multifocal intraocular lenses between May 2016 and July 2018. Binocular visual acuity for far, intermediate and near was tested in all cases. Ophthalmological evaluation included the measurement of binocular uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), uncorrected near visual acuity (UNVA) at 40 cm, uncorrected intermediate visual acuity (UIVA) at 70 cm, monocular visual defocus curve and the quality of life (QoL) questionnaire, National Eye Institute Visual Functioning Questionnaire - 25 ( NEI-VFQ 25). RESULTS: Postoperative UDVA was 0.00 and 0.09 logMAR (P<0.001), UIVA was 0.20 and 0.39 logMAR (P<0.001) and UNVA was 0.16 and -0.01 logMAR (P<0.001) in groups A and B, respectively; postoperative CDVA was -0.05 and 0.06 logMAR (P<0.001) in groups A and B, respectively. CONCLUSION: Both groups reported good subjective quality of vision regarding long, intermediate and short distances. Group A had a better performance for binocular UDVA, UIVA at 70 cm and CDVA, while regarding the monocular defocus curve, Group A outperformed Group B for long distances. Furthermore, Group B surpassed it in the short to very short distances, between the range of ≥2.00 D to 5.00 D of vergence. While Group A had a better performance regarding the vergences between 0.00 and 1.00 D (P<0.05) and at the vergence of +2.50 D (P=0.007). Group B outran Group A for UNVA at 40 cm.
RESUMEN
PURPOSE: To compare visual outcomes and performance between bilateral implantation of a diffractive trifocal intraocular lens (IOL) Acrysof®PanOptix® TFNT00 and blended implantation of two different near add power bifocal IOLs: Acrysof® Restor® SV25T0 in dominant eye and Acrysof® Restor® SN6AD1 in the nondominant eye. METHODS: This prospective, nonrandomized, consecutive and comparative study assessed 20 patients (40 eyes) who had bilateral cataract surgery performed using the IOLs described. Patients were divided into groups, bilateral trifocal implant and blended implant. Evaluation included measurement of binocular uncorrected and corrected distance visual acuity at 4 m (UDVA, CDVA) and uncorrected intermediate (60 cm) and near (at 40 cm) visual acuity; contrast sensitivity (CS) and visual defocus curve. RESULTS: Postoperative CDVA comparison showed no statistical significance between groups. UDVA was significantly better in the trifocal groups. Under photopic conditions, the trifocal group had better CS in higher frequencies with and without glare. The binocular defocus curve demonstrated a trifocal behavior in both groups, with the bilateral trifocal group exhibiting better performance for intermediate vision. CONCLUSION: Both lens combinations were able to provide good near, intermediate and distance vision, with the trifocal group showing significantly better performance at intermediate distances and better CS under photopic conditions.
RESUMEN
PURPOSE: To compare the optical performance and visual outcomes between two diffractive multifocal lenses: AMO Tecnis® ZMB00 and AcrySof® ReSTOR® SN6AD1. METHODS: This prospective, non-randomized comparative study included the assessment of 74 eyes in 37 patients referred for cataract surgery and candidates for multifocal intraocular lens implants. Exclusion criteria included existence of any other eye disease, previous eye surgery, high axial myopia, preoperative corneal astigmatism of >1.00 cylindrical diopter (D), and intraoperative or postoperative complications. Ophthalmological evaluation included the measurement of uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), distance-corrected near visual acuity (DCNVA), and distance-corrected intermediate visual acuity (DCIVA), with analysis of contrast sensitivity (CS), wavefront, and visual defocus curve. RESULTS: Postoperative UDVA was 0.09 and 0.08 logMAR in the SN6AD1 and ZMB00 groups, respectively (p=0.868); postoperative CDVA was 0.04 and 0.02 logMAR in the SN6AD1 and ZMB00 groups, respectively (p=0.68); DCIVA was 0.17 and 0.54 logMAR in the SN6AD1 and ZMB00 groups, respectively (p=0.000); and DCNVA was 0.04 and 0.09 logMAR in the SN6AD1 and ZMB00 groups, respectively (p=0.001). In both cases, there was an improvement in the spherical equivalent and UDVA (p<0.05). Under photopic conditions, the SN6AD1 group had better CS at low frequencies without glare (p=0.04); however, the ZMB00 group achieved better sensitivity at high frequencies with glare (p=0.003). The SN6AD1 and ZMB00 lenses exhibited similar behavior for intermediate vision, according to the defocus curve; however, the ZMB00 group showed a shorter reading distance than the SN6AD1 group. There were no significant differences regarding aberrometry between the two groups. CONCLUSION: Both lenses promoted better quality of vision for both long and short distances and exhibited a similar behavior for intermediate vision. The SN6AD1 and ZMB00 groups showed better results for CS under photopic conditions at low and high spatial frequencies, respectively.

RESUMO Objetivo: Comparar o desempenho óptico e resultado visual entre duas lentes multifocais difrativas: AMO Tecnis® ZMB00 e AcrySof® ReSTOR® SN6AD1. Métodos: O estudo prospectivo, comparativo não randomizado incluiu avaliação de 74 olhos em 37 pacientes com indicação de facectomia e candidatos a implante de lente multifocal. Critérios de exclusão foram: presença de outras doenças oculares; cirurgia ocular prévia; alta miopia axial; astigmatismo cornenano maior que 1,00 D cilíndrica; complicações intraoperatórias ou pós-operatórias. A avaliação oftalmológica contou com medida da acuidade visual para longe corrigida (CDVA) e não corrigida (UDVA), intermediária (DCIVA) e curta distância (DCNVA) com melhor correção óptica para longe; teste de sensibilidade ao contraste; análise de frente de onda e curva visual de Defocus. Resultados: A UDVA foi de 0,09 logMAR para o grupo SN6AD1 e 0,08 logMAR para o grupo ZMB00; com correção foi de 0,04 logMAR para SN6AD1 e 0,02 para o grupo ZMB00 (p>0,05). O grupo SN6AD1 obteve valor de 0,04 logMAR e o grupo ZMB00 de 0,09 logMAR para DCNVA (p<0,05) e DCIVA de 0,17 logMAR para SN6AD1 e 0,54 logMAR para ZMB00 (p=0,000). Houve melhora do equivalente esférico e da UDVA em ambos os grupos (p<0,05). Em condições fotópicas, o grupo SN6AD1 teve melhor sensibilidade ao contraste em baixas frequências sem ofuscamento (p<0,05), contudo grupo ZMB00 obteve melhor sensibilidade em altas frequências (p<0,05) com ofuscamento. As lentes SN6AD1 e ZMB00 obtiveram comportamento semelhantes para visão intermediária na curva de Defocus, porém, o grupo ZMB00 mostrou menor distância de leitura que o grupo SN6AD1. Não houve diferença com significância estatística relacionada à aberrometria na comparação dos dois grupos. Conclusão: As duas lentes promoveram melhor qualidade de visão para longe e perto e comportamento semelhante para visão intermediária. O grupo ZMB00 exibiu melhores resultados para sensibilidade ao contraste em condições fotópicas em alta frequência espacial e SN6AD1 em baixa frequência espacial.

PURPOSE: To assess patient characteristics, risk factors, outcomes, and the treatment of wound dehiscence (WD) in patients after corneal keratoplasty. METHODS: Retrospective chart review of 11 eyes of 11 patients with corneal grafts who underwent repair of WD from January 1, 2004 to December 31, 2012 at Hospital Oftalmologico de Brasilia. RESULTS: Eight (72.7%) patients were men and three were women. Six (54.5%) patients had deep anterior lamellar keratoplasty (DALK) and 5 had penetrating keratoplasty. The mean age at trauma was 31.1 years. The mean time from corneal keratoplasty to WD was 12.82 months (range, 3-33 months). The mean best-corrected visual acuity of patients before trauma was 20/60 (0.48 logMAR) and after final treatment was 20/160 (0.90 logMAR) (P=0.15). In one case, visual acuity decreased to no light perception because of retinal detachment and phthisis bulbi. Accidental blunt trauma and fall were the most common causes of WD. CONCLUSION: Patients who undergo corneal keratoplasty have a life-long risk of WD. The full-thickness rupture at the graft-host junction in our study suggests that the junction remains vulnerable, even following DALK, and can rupture with trauma. In our series, depending upon the severity of the trauma, postkeratoplastic WD can be associated with a good visual prognosis.

RESUMOObjetivo:Avaliar as características, os fatores de risco, resultados, e tratamento de pacientes que apresentaram deiscência traumática de sutura após transplante de córnea.Métodos:Estudo retrospectivo em que foram avaliados 11 olhos de 11 pacientes submetidos a transplante de córnea e que desenvolveram deiscência de sutura entre janeiro de 2004 e dezembro de 2012 no Hospital Oftalmológico de Brasília.Resultados:Oito (72,7%) pacientes eram homens e três mulheres. Seis (54,5%) pacientes foram submetidos a ceratoplastia lamelar anterior profunda (DALK) e 5 pacientes a ceratoplastia penetrante (PK). A média de idade dos pacientes no momento do trauma era de 31,1 anos. O tempo médio entre o transplante de córnea e a deiscência de sutura foi de 12,82 meses (variando de 3 a 33 meses). A melhor acuidade visual corrigida (AVCC) doa pacientes antes do trauma era de 20/60 (0,48 logMAR), e após o trauma era de 20/160 (0,90 logMAR) (P=0,15). Em um caso, a acuidade visual reduziu para sem percepção luminosa devido a descolamento de retina e posterior atrofia bulbar. O trauma ocular acidental e a queda da própria altura foram as principais causas de deiscência de sutura nos olhos transplantados.Conclusão:Pacientes previamente submetidos a transplante de córnea apresentam um risco prolongado de deiscência de sutura. A ruptura completa na junção doador-receptor no nosso estudo sugere que mesmo após um DALK a junção permanece vulnerável e pode romper com o trauma.

PURPOSE: To compare the efficiency of surgical procedures using three phaco tip designs in torsional phacoemulsification using the bevel-down technique. METHODS: In this prospective, comparative, masked study, patients were randomly assigned to have torsional coaxial microincision cataract surgery using the mini-flared 45-degree Kelman tip, reversed mini-flared 30-degree Kelman tip, or Sidewinder 30-degree Kelman tip. Clinical measurements included preoperative and 3-month postoperative corrected distance visual acuity (CDVA), endothelial cell counts (ECC), and preoperative and 1-day postoperative central corneal thickness (CCT). Intraoperative measurements included phaco time, torsional time, aspiration time, case time, cumulative dissipated energy (CDE), and balanced salt solution volume (BSS). RESULTS: The study evaluated 150 eyes of 150 patients. Intraoperatively, there was no statistically significant difference in cumulative dissipated energy, case time, torsional time, and aspiration time between the three tip configurations. However, less phaco time was used with the mini-flared 45-degree Kelman tip (p=0.02) than that with the Sidewinder 30-degree Kelman tip or reversed mini-flared 30-degree Kelman tip. The mini-flared 45-degree Kelman tip and the reversed mini-flared 30-degree Kelman tip required significantly less balanced salt solution volume than that required by the Sidewinder 30-degree Kelman tip (p=0.009). There was no statistically significant difference in corrected distance visual acuity and endothelial cell counts between tips 3 months postoperatively (p>0.05). CONCLUSION: All three tips were effective with no intraoperative complications. When using torsional phacoemulsification through microincisions and the prefracture technique with the bevel-down technique, the mini-flared 45-degree Kelman tip required a lower mean phaco time than the reversed mini-flared 30-degree Kelman tip and the Sidewinder 30-degree Kelman tip.

Objetivo: Comparar a eficácia cirúrgica da facoemulsificação com tecnologia torcional utilizando 3 modelos diferentes de ponteiras. Métodos: Neste estudo prospectivo, randomizado, mascarado, os pacientes foram aleatoriamente distribuídos para serem submetidos a cirurgia de facoemulsificação coaxial torcional utilizando a ponteira Kelman mini-flared de 45 graus, ou Kelman reversed mini-flared de 30 graus ou Kelman Sidewinder de 30 graus. Os parâmetros avaliados incluíram: acuidade visual com correção (AVCC) para longe; contagem de células endoteliais (CCE) pré-operatória e pós-operatória, ao final de 3 meses; espessura corneana central (ECC) pré-operatória e no primeiro dia pós-operatório. Medidas intraoperatórias incluíram tempo de facoemulsificação, tempo de energia torcional, tempo da aspiração, tempo cirúrgico, energia dissipada acumulada (CDE) e volume de solução salina balanceada (BSS). Resultados: Este estudo avaliou 150 olhos de 150 pacientes. No intraoperatório, não foram observadas diferenças significativas na energia dissipada acumulada, tempo de facoemulsificação, tempo de energia torcional, e tempo de aspiração entre os 3 modelos de ponteira. No entanto, foi utilizando menos tempo de faco com a ponteira Kelman mini-flared de 45 graus (p=0,02) quando comparado às ponteiras Kelman Sidewinder de 30 graus e reversa mini-flared de 30 graus. A ponteira Kelman mini-flared de 45 graus e a reversa mini-flared de 30 graus utilizaram menos solução salina balanceada quando comparado à ponteira Sidewinder de 30 graus (p=0,009). Não foram observadas diferenças significativas na acuidade visual com correção, contagem de células endoteliais e espessura corneana central entre as diferentes ponteiras ao final do estudo (p=0,05). Conclusão: As 3 ponteiras foram eficazes e não apresentaram complicacões intraoperatórias.

PURPOSE: To compare the anti-inflammatory efficacy of ketorolac of tromethamine 0.4% and nepafenac 0.1% eye drops for prophylaxis of cystoid macular oedema (CME) after small-incision cataract extraction. METHODS: Patients were assigned randomly to three groups. Group 1 patients received a topical artificial tear substitute (placebo); group 2 received ketorolac tromethamine 0.4% (Acular LS, Allergan) and group 3 received nepafenac 0.1% (Nevanac, Alcon). The incidence and severity of CME were evaluated by retinal foveal thickness on optical coherence tomography (OCT) after 1, 4 and 12â weeks. RESULTS: One hundred and twenty-six eyes of 126 patients were included in this study. The between-group differences in visual outcomes, central corneal thickness and endothelial cell density were not statistically significant. In all retinal thickness measurements, an increase was detected starting from the postoperative first week until 12â weeks. There was no statistically significant difference between the three groups in any measurement performed by spectral-domain OCT. CONCLUSIONS: Used prophylactically after uneventful cataract surgery, non-steroidal anti-inflammatory drugs were not efficacious in preventing macular oedema compared with placebo. TRIAL REGISTRATION NUMBER: ClinicalTrials: NCT02084576.

Objetivo: Medir e comparar o tamanho e forma de capsulotomias realizadas com laser de femtossegundo com os de capsulorrexes curvilíneas contínuas (CCC) realizadas com auxilio guiado por imagem digital e avaliar o resultado refracional. Métodos: Durante cirurgia de catarata, 40 olhos de 40 pacientes tiveram a capsulotomia realizada com auxílio do laser de femtossegundo e seus resultados foram comparados com os de 40 olhos de 40 outros pacientes que tiveram a capsulorrexe guiada por sistema de imagem digital. Os parâmetros de circularidade, forma e overlap foram medidos usando o Adobe Photoshop (Adobe Systems Inc.) e os resultados refracionais pós-operatórios foram avaliados em ambos os grupos. Resultados: Os diâmetros, tamanho e forma de alta precisão e previsibilidade foram atingidos com laser de femtossegundo e houve diferença estatística entre os grupos. Quando comparado o equivalente esférico entre os grupos, não houve diferença estatística. Conclusão: As capsulotomias realizadas pelo laser de femtossegundo possuem circularidade programada, diâmetro pretendido e valores de desvio padrão médios, indicando resultados reprodutíveis mais elevados. No entanto, CCC realizada por um cirurgião experiente com auxílio guiado de imagem digital, com configurações apropriadas, fornece resultados semelhantes e sugere que diferentes técnicas são igualmente eficazes. .
Purpose: To measure and compare size and shape parameters of femtosecond laser capsulotomy with manually continuous curvilinear digital guided capsulorhexis (CCC) and their refractive outcomes. Methods: Laser capsulotomies in 40 eyes of 40 patients were performed using LenSx femtosecond laser device (Alcon, Forthworth, US) and its results were compared with the CCC digital guided carried out in 40 eyes of 40 patients using the Callisto Eye digital image system (Zeiss, Germany). Capsulorhexis circularity, shape and capsule overlap were measured using Adobe Photoshop (Adobe Systems Inc.) and postoperative refraction outcomes were evaluated in both groups. Results: Highly accurate and predictable capsulotomy diameter, size and shape were achieved with femtosecond laser capsulotomy compared with capsulorhexis and showed statistical difference between groups. Spherical equivalent comparison between groups showed no statistical difference. Conclusions: Femtosecond laser anterior capsulotomy with programed circularity had the intended diameter with average standard deviation values, indicating higher reproducible outcomes. Capsulorhexis performed by an experienced surgeon with auxiliary image guide and appropriate settings provides similar results our results suggest that different techniques are equally effective. .

PURPOSE: To assess the postoperative outcomes of a novel toric multifocal in traocular lens (IOL) in patients with cataract and corneal astigmatism. METHODS: This prospective nonrandomized study included patients with cataract, corneal astigmatism, and a motivation for spectacle independence. In all patients, a Rayner M-flex® T toric IOL was implanted in the capsular bag. Three months after surgery, the distance, intermediate, and near visual acuities; spherical equivalent; residual refractive astigmatism; defocus curve; and contrast sensitivity were evaluated. A patient satisfaction and visual phenomena questionnaire was administered to all patients. RESULTS: Thirty-four eyes of 18 patients were included in this study. Three months after surgery, the mean corrected distance visual acuity (logMAR) was 0.00 ± 0.08 at 6 m, 0.20 ± 0.09 at 70 cm, and 0.08 ± 0.11 at 40 cm. Uncorrected distance vision acuity was 20/40 or better in 100% eyes. The preoperative mean refractive cylinder (RC) was -2.19 (SD: ± 0.53). After a 3-month follow-up, the average RC was -0.44 D (SD: ± 0.27; p<0.001). Contrast sensitivity levels were high. At the last follow-up, 87.5% patients were spectacle-independent for near, intermediate, and distance vision, and approximately 44% patients reported halos and glare. CONCLUSION: Toric multifocal IOL implantation in patients with cataract and corneal astigmatism using the Rayner M-flex® T toric IOL was a simple, safe, and accurate option. This technology provides surgeons with a feasible option for meeting patient expectations of an enhanced lifestyle resulting from decreased spectacle dependence.

Objetivo: Avaliar o resultado pós-operatório de uma nova lente intraocular (LIO) multifocal tórica implantada em pacientes com catarata e astigmatismo corneano. Métodos: Estudo prospectivo não randomizado envolvendo pacientes com catarata, astigmatismo corneano, e motivação para eliminar a dependência dos óculos. Em todos os casos, a lente intraocular tórica Rayner M-flex® T foi implantada dentro do saco capsular. Três meses pós-operatório foram avaliados: acuidade visual para longe, intermediário e perto; equivalente esférico; astigmatismo refracional residual; curva de defocus e sensibilidade ao contraste. Ao final do estudo um questionário referente à satisfação visual foi aplicado. Resultados: Trinta e quatro olhos de 18 pacientes foram incluídos no estudo. Após 3 meses de pós-operatório, a acuidade visual corrigida para longe (logMAR) era de 0,00 ± 0,08 a 6 m, 0,20 ± 0,09 a 70 cm e 0,08 ± 0,11 a 40 cm. A acuidade visual sem correcão foi de 20/40, ou melhor, em 100% dos olhos. A média do cilindro refracional pré-operatório era de -2,19 (DP: ± 0,53). Após o seguimento de 3 meses a média do cilindro refracional era de -0,44 D (DP: ± 0,27) (p<0,001). Os níveis de sensibilidade ao contraste foram elevados. Ao final do seguimento, 87,5% dos pacientes estavam independentes dos óculos para perto, intermediário e para longe, e aproximadamente 44% dos pacientes relatavam halos e glare. Conclusão: O implante de uma lente intraocular multifocal em pacientes com catarata e astigmatismo corneano utilizando a lente intraocular tórica Rayner M-flex® T foi uma opção simples, segura e acurada.

OBJETIVO: Elaborar e validar o questionário de qualidade de vida na versão do idioma português. MÉTODOS: O questionário "Cataract TyPESpecification" modificado foi desenvolvido especificamente para avaliar a qualidade de vida pós-cirurgia de catarata. O questionário avaliou 10 itens status funcionais por meio de 18 perguntas. Foi aplicado por um único examinador, com o objetivo de graduar a satisfação visual de 0 a 10 (0 muito insatisfeito; 5 neutro; 10 muito satisfeito). Houve estudo prospectivo comparativo, não randomizado, que incluiu 142 olhos de 71 pacientes com catarata da Universidade de São Paulo. A avaliação oftalmológica contou com medida da acuidade visual para longa, intermediária e curta distâncias, sem correção e com a melhor correção óptica e questionário de satisfação. Foi submetido a um questionário de satisfação quanto à acuidade visual e fenômenos fóticos. Todos os exames foram realizados com 6 meses de pós-operatório. RESULTADOS: A média de idade dos pacientes foi de 60,7 ± 6,6 anos no grupo Tecnis, 63,1 ± 4,4 anos no grupo Restor e 63,7 ± 4,2 anos no grupo SN60AT/SN60WF. A acuidade visual para perto não-corrigida e a corrigida para longe foram estatisticamente superiores nos grupos Restor® e Tecnis® comparadas ao grupo SN60AT/SN60WF (p<0,001). Não houve diferença estatística entre os grupos quando comparadas a acuidade visual para longe não-corrigida e a melhor corrigida (p=0,56). O questionário de satisfação apresentou maior independência de óculos a favor da Tecnis® (9,3/10) e Restor® (8,7/10), mas com mais queixas de halos (Restor® 18,8%; Tecnis® 21,7%) e glare (Restor® 25%; Tecnis® 26,1%) do que no grupo SN60AT/SN60WF. CONCLUSÃO: A Restor® e Tecnis® apresentaram melhor acuidade visual para perto do que o grupo SN60AT/SN60WF. As lentes Restor® e Tecnis® apresentaram maior satisfação na visão de perto e independência do uso de óculos e fenômenos fóticos do que as lentes monofocais...
PURPOSE: Development and validation of quality of life questionnaire in pseudophakic patients in Portuguese. METHODS: The modified Cataract TyPESpecification questionnaire was specifically developed to assess quality of life after cataract surgery, functional status evaluated with 10 items and contains 18 questions. All questions were applied by a single examiner, with the goal of graduating visual satisfaction from 0 to 10 (0 means very dissatisfied, 5 neutral, 10 very satisfied).This prospective comparative study included 142 eyes of 71 patients in Sao Paulo University. The ophthalmologic evaluation performed included near, intermediate and distance corrected and uncorrected visual acuity and quality of life questionaire. The minimum follow-up was 6 months. RESULTS: The mean age of patients was 60.7± 6.6 years in theTecnis®MF, 63.1 ±4.4 years in-groupRestor®63.7±4.2 years in-group SN60AT/SN60WF. Uncorrected and distance-corrected near visual acuity were statistically higher in theRestor® and Tecnis® groups compared to the SN60AT/SN60WF group (p<0.001). There were no statistical differences between groups comparing uncorrected and best-corrected distance visual acuity (p=0.56). Satisfaction questionnaire showed high glasses independence fortheTecnis®MF (9.3 /10) and Restor® (8.7 /10), but with more unsatisfied of halos (18.8% Restor®, Tecnis®21, 7%) and glare (Restor® 25%;Tecnis®26.1%) than the group SN60AT/SN60WF. CONCLUSION: Cataract patients who received multifocal (Restor®; Tecnis®MF) IOLs at time of surgery obtained better uncorrected and distance corrected near visual acuity and reported better overall vision, less limitation in visual function, less spectacle dependency, and more glare or halo than those who received monofocal (SN60AT; SN60WF) IOLs. Cataract TyPESpecification questionnaire was a strong predictor of change in patient satisfaction caused by cataract surgery.

MÉTODOS: Estudo prospectivo comparativo, não randomizado, que incluiu 142 olhos de 71 pacientes com catarata, provenientes do ambulatório de oftalmologia do HC-FMUSP. A avaliação oftalmológica contou com medida da acuidade visual para longa, intermediária e curta distância, sem correção e com a melhor correção óptica, teste de sensibilidade ao contraste, pupilometria e análise de frente de onda por meio do aberrômetro. Todos os exames foram realizados com seis meses de pós-operatório. RESULTADOS: A média de idade dos pacientes foi de 60,7±6,6 anos no grupo Tecnis, 63,1±4,4 anos no grupo Restor e 63,7±4,2 anos no grupo monofocal (SN60AT no olho contralateral SN60WF). A acuidade visual para perto não corrigida e corrigida para longe foi estatisticamente superior nos grupos multifocal Restor e multifocal Tecnis em comparação ao grupo monofocal SN60AT/SN60WF (p<0,001). Não houve diferença estatística entre os grupos na comparação da acuidade visual para longe (p=0,56). A sensibilidade ao contraste fotópica monocular foi estatisticamente inferior nos grupos Restor e Tecnis (p<0,001). A SN60AT apresentou maior aberração esférica comparada a todas as outras lentes (p<0,001). A Tecnis se mostrou com menores valores médios de aberrações esféricas na comparação com a Restor (p<0.001). CONCLUSÃO: A Restor e Tecnis apresentaram melhor acuidade visual para perto do que o grupo monofocal SN60AT/SN60WF. Todas as lentes intraoculares promoveram boa visão para longe. O grupo da Tecnis apresentou melhor sensibilidade de contraste, menos aberrações ópticas e melhor visão intermediária que o grupo Restor.
