RESUMEN

The problem of treating purulent scleral infections, rare but extremely severe complication of ophthalmic surgeries, remains unresolved. This article presents a case of successful surgical treatment of purulent scleritis - interlamellar scleral abscess - that developed in a patient after repeat penetrating keratoplasty performed due to infectious lysis of the transplant. Although the first keratoplasty was performed for acanthamoeba keratitis, there were no signs of acanthamoeba invasion in the transplant at the time of the second surgery. Scleritis manifested as an infiltrate with pus penetrating the anterior chamber and development of keratoiridocyclitis. During surgery, the abscess cavity was opened, irrigated with an antiseptic solution, and drained into the subconjunctival space; the anterior chamber was irrigated with balanced salt solution through a separate paracentesis. No infection recurrences were noted in the postoperative period and the corneal transplant remained clear.

RESUMEN

We report the successful reconstruction of suture exposure with the oral mucosal graft in a patient with suture exposure after transscleral-sutured posterior chamber intraocular lens implantation. The 70-year-old patient had a history of vitreoretinal surgery and transscleral-sutured posterior chamber intraocular lens implantation after complicated cataract surgery. He was referred to our department because of suture exposure. The best-corrected visual acuity was 20/2000 OD and 20/50 OS. We observed exposed PC9 sutures from both the nasal and temporal conjunctiva in the right eye. The patient showed appearance of scleromalacia in the same regions, so scleral flap surgery was not considered. Despite both tenoplasty and amniotic membrane transplant procedures, exposure could not be controlled. Instead, the patient received oral (buccal) mucosal graft transplant to the resistant exposure areas. A single layer of protective amniotic membrane was transplanted over the buccal mucosal graft. This method resulted in effective control of the exposed area. In conclusion, an oral mucosal graft can be used in many ocular pathologies that require conjunctival reconstruction because of the simplicity of tissue excision from the mucosa, allowing adequate tissue excision, durability of the obtained tissue, and ease of use. Our case report highlights that resistant transscleral-sutured posterior chamber intraocular lens suture exposure can be successfully managed with oral mucosal grafting.

RESUMEN

BACKGROUND: This study aims to evaluate the clinical outcomes and efficacy of a modified tectonic corneoscleral graft (TCG) in patients suffering from devastating corneoscleral infections. METHODS: Thirty-eight eyes from 38 patients who underwent the modified TCG were included in this study. The outcomes measured were recurrence rates, best-corrected visual acuity (BCVA), ocular surface stability, postoperative complications, and graft survival. RESULTS: Among the 38 patients, 23 had fungal infections, 9 had bacterial infections and 6 had Pythium insidiosum infections. At the final follow-up, with an average duration of 25.1 ± 8.6 months, the rate of monocular blindness decreased from 100 to 58%. Significant improvements in LogMAR BCVA were observed from preoperative to postoperative measurements (P < 0.001). Thirty-two eyes (84.2%) maintained a stable ocular surface. The survival rate of ocular surface stability was 84.2%±5.9% at one year and 57.7%±9.7% at three years post-surgery. Twenty eyes (52.6%) retained a clear graft, with a survival rate for graft clarity was 81.6%±6.3% at one year and 36.0%±10.8% at three years post-surgery. The incidence of immune rejection was 36.8%. Corneal epithelial defects were observed in ten patients, and choroidal detachment occurred in four patients. No cases of elevated intraocular pressure were detected. CONCLUSIONS: The modified TCG is effective in eradicating infections, preserving the eyeball, and maintaining useful vision in cases of devastating corneoscleral infections. Regular use of tacrolimus, timely administration of glucocorticoids, and good patient compliance can help mitigate postoperative challenges.

RESUMEN

OBJECTIVE: To assess the efficacy and safety of using the adjustable flanged technique for secondary implantation of four-point scleral­fixated posterior chamber intraocular lenses with two parallel 6-0 polyglactin sutures. METHODS: Two parallel 6-0 polyglactin sutures were passed separately through the two haptics on the horizontal line of the 4-haptic IOL. The four externalized sutures were then trimmed and cauterized to form flanges. The best corrected visual acuity, intraocular pressure, and complications in all patients were observed and recorded. RESULTS: The flanged technique using two parallel 6-0 polyglactin sutures was applied to 14 aphakic eyes. The average preoperative best corrected visual acuity was 1.00 ± 0.88 LogMAR (Snellen 20/200), which improved to 0.42 ± 0.38 LogMAR (Snellen 20/48) at the final follow-up (P = 0.004). None of the patients experienced vitreous hemorrhage, low intraocular pressure, or issues with exposed or broken sutures. CONCLUSION: The simplicity of the technique, along with its ability to accommodate adjustments post-implantation, allows for optimal positioning and reduces risks like IOL tilt or dislocation. Overall, this is a promising approach to secondary IOL implantation, with potential benefits for both patient outcomes and surgical efficiency.

RESUMEN

BACKGROUND: The present study elucidates a common significant postoperative complication of micropulse transscleral laser treatment (mTLT) and explores its potential management strategies for younger patients with good central vision. CASE PRESENTATION: Three younger Chinese glaucoma patients with good central vision maintained high intraocular pressures (IOPs) (36, 25, and 30 mmHg) on maximally tolerated topical anti-glaucoma medications. All patients were treated with mTLT because of a higher risk of complications with filtering surgery. After the procedure, their best-corrected visual acuities were not significantly changed, IOPs were significantly decreased, and the number of topical anti-glaucoma medicines was gradually decreased. However, all patients complained about reduced near visual acuity (NVA) for 1-5 months. Slit-lamp examination revealed pupillary dilation, and binocular accommodative function examination indicated accommodation loss. After treatment with 2% topical pilocarpine, all patients reported an improvement in NVA. Among them, we could observe pupillary constriction, recovery of accommodation function, and improved NVA, even discontinuation of pilocarpine in Patient 2. CONCLUSION: In younger patients with good central vision, topical pilocarpine might ameliorate accommodation loss and pupillary dilation after mTLT.

RESUMEN

PURPOSE: To compare the outcomes of anterior chamber intraocular lens (AC-IOL) implantation versus the four-flanged scleral fixation technique in eyes with loss of capsular support during routine cataract surgery. METHODS: This was a retrospective cohort study of all patients in whom an IOL was implanted either during or after short-term aphakia due to loss of capsular and sulcus support in a routine cataract surgery with at least 6 months of follow-up time between 2015 and 2023 in a tertiary medical center in Israel. Two different IOL implantation techniques were compared: the implantation of an angle-supported ACIOL and four-flanged scleral fixation. Main outcome measures included postoperative complications such as pseudophakic bullous keratopathy, loss of intraocular pressure control and glaucoma, IOL subluxation, and retinal detachment. RESULTS: Sixty-five eyes of 65 patients were included in the study, 33 eyes in the AC-IOL group and 32 eyes in the flange group. Follow-up time was 29.92 ± 20.02 months in the AC-IOL group and 20.17 ± 15.56 months in the flange group (P = .087). Pseudophakic bullous keratopathy was observed in 10 (30.3%) patients in the AC-IOL group and in 1 (3.1%) patient in the flange group (P = .04). This association remained significant using survival analysis (P = .006). In 4 (12.1%) patients in the AC-IOL group, a glaucoma filtering procedure was performed to control the intraocular pressure compared with none in the flange group (P = .042). CONCLUSIONS: In the setting of loss of capsular support during routine cataract surgery, four-flanged scleral fixation showed an overall lower rate of complications and significantly reduced rate of subsequent surgical interventions.

RESUMEN

PURPOSE: To assess the refractive predictability of the Carlevale sutureless scleral fixation intraocular lens (IOL) (Sole-ko IOL Division) power calculation. METHODS: This retrospective, non-comparative, interventional case series included patients without a capsular support having undergone sutureless scleral fixation IOL implantation in two French hospitals between October 2019 and April 2022. IOL calculation was performed with the Barrett Universal II, Hoffer Q, Holladay 1, and SRK/T formulas with constant optimization to achieve a mean arithmetic prediction error equal to zero. The main outcomes were prediction error (PE) and its standard deviation (SD-PE), the median absolute error (MedAE), the mean absolute error (MAE), and the percentage of eyes with PE within ±0.50, ±1.00 and ±2.00 diopters (D) 6 months after surgery. RESULTS: Thirty eyes of 30 patients were included in the study. The mean age was 66.6 years, the mean axial length was 24.31 mm, and the mean keratometry was 43.07 D. SDPE ranged from 0.73 to 0.87 D depending on the formula. MedAE ranged from 0.38 to 0.61 D, and MAE from 0.52 to 0.68 D. Between 46.7% and 56.7% of eyes were within ±0.50 D, 76.7% and 90.0% were within ±1.00 D, and 96.7% were within ±2.00 D of target equivalent. No statistically significant difference was observed between the four formulas for any outcomes. CONCLUSIONS: This study confirmed that the design of the Carlevale sutureless scleral fixation IOL provides satisfactory refractive results. [J Refract Surg. 2024;40(8):e527-e532.].

RESUMEN

BACKGROUND: A modified surgical technique of sutured scleral fixated intraocular lens (SSF-IOL) was applied in a patient with post-traumatic aniridia and aphakia. CASE PRESENTATION: A 51-year-old man was referred to our clinic with decreased vision (finger count) in his right eye. This patient had previously undergone primary repair of the ruptured globe and pars plana vitrectomy to manage ocular trauma in the same eye. On presentation, the best corrected visual acuity in his right eye was 20/40. The slit lamp examination of his right eye revealed loss of total iris and lens. Corneal endothelial cell density was 1462 cells/mm2. Fundoscopic examination of the right eye revealed a retinal attachment. For IOL implantation, a rigid poly methyl methacrylate IOL was used with a 2-point scleral fixation performed using a polypropylene suture. One year postoperatively, the uncorrected distance visual acuity was 20/32, and the manifest refraction was - 0.5/-1.5 × 130 (20/20). Pentacam revealed that the astigmatism of the anterior corneal surface and the total cornea was 1.1 D (axis: 59.8°) and 1.0 D (axis: 35.6°), respectively. The horizontal (3°-183°) cross-section image displayed an IOL with a 1° tilt and 0.425 mm decentration. The patient reported no dysphotopsia or photophobia and was satisfied with the visual results. OPD-scan III revealed that higher-order aberrations in the right eye were slightly higher than those in the left eye. No suture-related or other serious complications were observed. CONCLUSION: The modified SSF-IOL technique can offer improved visual quality for patients with aniridia and aphakia by ensuring proper IOL positioning and reducing astigmatism.

RESUMEN

BACKGROUND: Implantation of intraocular lens in the capsular bag has become the standard of care in aphakic state. However, in the absence of capsular support, several techniques and intraocular lenses are available. Our study aims to report the safety, efficacy, and clinical outcomes of transconjunctival intrascleral intraocular lens fixation with Yamane's double-needle technique and flanged haptics. METHODS: Prospective, observational study with some retrospective data collection. The study enrolled 13 patients (16 eyes) who underwent transconjunctival intrascleral fixation of an intraocular lens with Yamane's technique between June 2017 and April 2019 at Dhahran Eye Specialist Hospital and King Fahd University Hospital. All patients underwent preoperative and postoperative comprehensive evaluation, including uncorrected and best-corrected vision, intraocular pressure, slit-lamp examination, dilated fundus examination, and ultrasound biomicroscopy. We excluded patients with visually significant coexistent pathology such as retinal diseases, glaucoma, follow-up less than three months, and combined surgery such as keratoplasty. RESULTS: The mean preoperative uncorrected visual acuity was 1.50 logMAR, and it improved to 0.60 logMAR. The mean preoperative best-corrected visual acuity was 0.70 logMAR, and it improved to 0.40 logMAR. The median safety index was 2.0, and the median efficacy index was 1.58. The postoperative complications included iris capture by the intraocular lens in one eye (7.7%), haptic extrusion in one eye (7.7%), and transient cornea edema in one eye (7.7%). There were no detected reports during the follow-up period of postoperative retinal detachment, choroidal detachment, elevation of the intraocular pressure (> 25 mmHg), hypotony, hyphema, vitreous hemorrhage, or endophthalmitis. CONCLUSIONS: The transconjunctival intrascleral fixation of an intraocular lens is safe and effective with a short learning curve and was not associated with significant intraoperative or postoperative complications.

RESUMEN

PURPOSE: This study aimed to compare the safety and effectiveness of intraocular pressure reduction between micropulse transscleral cyclophotocoagulation and "slow cook" transscleral cyclophotocoagulation in patients with refractory primary open-angle glaucoma. METHODS: We included patients with primary open angle glaucoma with at least 12 months of follow-up. We collected and analyzed data on the preoperative characteristics and postoperative outcomes. The primary outcomes were a reduction of ≥20% of the baseline value (criterion A) and/or intraocular pressure between 6 and 21 mmHg (criterion B). RESULTS: We included 128 eyes with primary open-angle glaucoma. The preoperative mean intraocular pressure was 25.53 ± 6.40 and 35.02 ± 12.57 mmHg in the micropulse- and "slow cook" transscleral cyclophotocoagulation groups, respectively (p<0.001). The mean intraocular pressure was reduced significantly to 14.33 ± 3.40 and 15.37 ± 5.85 mmHg in the micropulse- and "slow cook" transscleral cyclophotocoagulation groups at the last follow-up, respectively (p=0.110). The mean intraocular pressure reduction at 12 months was 11.20 ± 11.46 and 19.65 ± 13.22 mmHg in the micropulse- and "slow cook" transscleral cyclophotocoagulation groups, respectively (p<0.001). The median preoperative logMAR visual acuity was 0.52 ± 0.69 and 1.75 ± 1.04 in the micropulse- and "slow cook" transscleral cyclophotocoagulation groups, respectively (p<0.001). The mean visual acuity variation was -0.10 ± 0.35 and -0.074 ± 0.16 in the micropulse- and "slow cook" transscleral cyclophotocoagulation, respectively (p=0.510). Preoperatively, the mean eye drops were 3.44 ± 1.38 and 2.89 ± 0.68 drugs in the micropulse- and "slow cook" transscleral cyclophotocoagulation groups, respectively (p=0.017), but those were 2.06 ± 1.42 and 1.02 ± 1.46 at the end of the study in the "slow cook" and micropulse transscleral cyclophotocoagulation groups, respectively (p<0.001). The success of criterion A was not significant between both groups. Compared with 11 eyes (17.74%) in the "slow cook" transscleral cyclophotocoagulation group, 19 eyes (28.78%) in the micropulse transscleral cyclophotocoagulation group showed complete success (p=0.171). For criterion B, 28 (42.42%) and 2 eyes (3.22%) showed complete success after micropulse- and "slow cook" transscleral cyclophotocoagulation, respectively (p<0.001). CONCLUSION: Both techniques reduced intraocular pressure effectively.

RESUMEN

BACKGROUND: The purpose of the study was to assess visual outcomes, complications, intraocular lens (IOL) stability, and corneal status after sutured scleral-fixated intraocular lens implantation combined with penetrating keratoplasty (PKP). METHODS: This retrospective single-arm cohort study included patients who underwent PKP and sutured scleral-fixated intraocular lens implantation between 2013 and 2018 at the Dhahran Eye Specialty Hospital. The eyes were examined postoperatively at 1, 3, 6, 12, and 24 months. Corneal status, complications, and IOL status were also evaluated periodically, and the number of eyes with a BCVA of > 20/200 was recorded. RESULTS: Twenty-two eyes from 22 patients were included. The median duration of follow-up was 3 (IQR 1.8; 4.4) years. Reasons for surgery were traumatic globe rupture (six eyes, 27.3%), bullous keratopathy (nine eyes, 40.1%), failed previous graft (five eyes, 22.7%), and corneal scarring (two eyes, 9.1%). Twelve (54.5%) eyes showed a BCVA of > 20/200 (non-blind) at 12 months after surgery and only five (22.7%) before surgery. Twelve months after surgery, 13 patients showed an improvement in BCVA in two lines (59.1%), seven remained the same (31.8%), and 2 deteriorated (9.1%). The indication for surgery (p = 0.2) and the stability of the sutured-scleral fixated IOL (p = 0.8) were not associated with an improvement in BCVA at the final follow-up. The corneal graft remained clear in nine eyes (40.9%) at a median duration of 3 years. The overall average survival period for all corneal grafts was 42.9 months. CONCLUSIONS: The combination of sutured scleral-fixated intraocular lens implants and PKP is an effective intervention for preserving visual acuity in patients with complex cases. However, the risk of graft failure and then need for repeat transplantation should be taken into consideration.

RESUMEN

We aim to observe the posterior scleral reinforcement (PSR) clinical outcomes of children with high myopia and analyze the retinal vessel alteration before and after PSR by using angiography optical coherence tomography (angio-OCT). Fifty-six pediatric participants (112 eyes) clinically diagnosed high myopia were recruited and were treated by PSR in Shanghai Children's Hospital from June 1, 2021 to May 1, 2023. The average age ranged from 5.42 to 14.83 years (mean 8.83 years) and mean follow up duration was 8.7 months (3-24 months). The axial length (AL) was significantly shortened after PSR (p < 0.05). The spherical equivalent (SE) and the best-corrected visual acuity (BCVA) were also improved without severe rejection in the follow-up. Compared with baseline, angio-OCT parafoveal vessel indices including vascular area density (VAD) and vascular skeleton density (VSD) on the superficial capillary plexus layer (SCPL), as well as VAD and vessel perimeter index (VPI) on the deep capillary plexus layer (DCPL), were significantly increased after PSR surgery (p < 0.05). VPI on the SCPL, vascular diameter index (VDI) and VSD on the DCPL were also improved without statistical difference after PSR. The VSD on SCPL, VAD on DCPL of the right eyes and the VPI on SCPL of the left eyes were significantly increased after PSR (p < 0.05). PSR surgery can shorten the AL and can stable BCVA and SE in high myopia children. The angio-OCT parameters indicated that the retinal microcirculation supply was significantly improved after PSR.

RESUMEN

INTRODUCTION: Cataract surgery constitutes one of the highest volume surgeries performed worldwide approximating 10 million annually, varying from 100 to 6000 per million population. Implantation of scleral fixated intra-ocular lens (SFIOL) is getting popular in managing difficult situations like aphakia, subluxated lens, and dislocated cataracts. OBJECTIVE: This retrospective series evaluated our experience with foldable 3-piece acrylic SFIOL implantation for various challenging surgical scenarios in a tertiary care ophthalmic institute in the southern part of India. RESULTS: The data from the first 150 patients, those operated in our hospital in the aforementioned technique, have been reviewed and analyzed. The mean age of the population was 46.43 years. The most common indication was found to be surgical aphakia (34.66%) followed by traumatic subluxated lens (8.33%). Postoperative BCVA at 3 months improved to 0.255 on the LogMAR scale from preoperative BCVA of 0.795 (P < 0.01). Intraocular pressure was found to stabilize over 3 months follow-up (P = 0.002). The various intraoperative and postoperative complications have been recorded. Ten patients required resurgery out of which eight had postoperative haptic dislocation. A detailed comparison of the role of a surgeon's experience in influencing outcomes has been evaluated. CONCLUSION: The technique offers physiological IOL placement using minimal surgical maneuvers. We strongly recommend this as a technique of choice for the surgical management of complicated scenarios with inadequate capsular bag support.

RESUMEN

INTRODUCTION: The use of the PreserFlo microshunt is gaining popularity owing to its ease of implantation and reduced need for postoperative intervention compared to conventional trabeculectomy. PATIENT CONCERNS: However, microshunt exposure remains a severe complication of PreserFlo surgery, particularly in patients with a thin Tenon capsule and conjunctiva. However, the actual thickness and intensity of the Tenon capsule or conjunctiva can be confirmed only during surgery. DIAGNOSIS: Exfoliation glaucoma with previous several glaucoma surgeries with thinner Tenon capsule or conjunctiva. INTERVENTIONS: We performed PreserFlo implantation with a surgical technique to recover a thin Tenon capsule and conjunctiva by creating a half-thickness rectangular scleral flap under the shunt and covering it over the microshunt until the distal part, similar to the bridge. OUTCOMES: The patient had better intraocular pressure control with positive cosmetic appearance using this technique. CONCLUSION: This technique will be beneficial for both preventing exposure and holding down the top, in addition to improving cosmetic appearance.

RESUMEN

OBJECTIVE: This study examined the long-term outcomes of scleral-sutured fixated intraocular lenses (SSIOLs) in patients with uveitis. PATIENTS AND METHODS: Retrospective, consecutive review of uveitis patients with SSIOL fixation from January 2017 to December 2020. SSIOL techniques included four-point fixation with the Akreos A060 or enVista MX60 (Bausch + Lomb) lens, or Hoffman's pockets rescue. RESULTS: Thirteen eyes of 13 patients received an SSIOL (9 AO60, 2 MX60, 2 Hoffman's pockets). Diagnoses included pan- (9), anterior (2), and posterior uveitis (2). Average LogMAR best-corrected visual acuity pre- and postoperatively was 1.01 (Snellen ∼20/200) and 0.50 (Snellen ∼20/60), respectively (P = 0.003). No patients had postoperative SSIOL dislocation or conjunctival suture erosion. Six patients (46%) had uveitis flares postoperatively. Average follow-up was 50.2 months (range = 36.8 to 67.5). CONCLUSION: This series demonstrates a 0% dislocation and suture exposure rate. Risks of uveitis flares postoperatively are high despite aggressive perioperative control but are manageable with current treatments; therefore, patients must be continually monitored.

RESUMEN

PURPOSE: This study comparatively analyzed the morphology of eye tissues after laser exposure using the latest generation of transscleral laser techniques - micropulse transscleral cyclophotocoagulation (MP-TSCPC) and laser activation of scleral hydropermeability (LASH) - in an anatomical experiment. MATERIAL AND METHODS: The study used pulsed-periodic radiation of an Er-glass fiber laser (λ=1.56 µm) and radiation of a diode laser (λ=0.81 µm) in the micropulse mode. A comparative morphological evaluation of histological preparations of target scleral and ciliary body (CB) tissues was performed with the study of laser-induced changes occurring after LASH and MP-TSCPC. RESULTS: The study of histological preparations obtained after MP-TSCPC and LASH did not reveal any noticeable signs of an inflammatory reaction or significant destructive changes. There were no signs of pronounced coagulative changes in the form of disorganization of connective and muscle tissue in the exposure area. At the same time, MP-TSCPC was accompanied by thinning and discontinuity of the CB pigment epithelium in the projection of its flat part and expansion of the gaps between the anterior connective tissue fibers fixing the CB to the sclera, which is likely a factor contributing to uveoscleral outflow. After LASH, in the irradiated areas at the level of the outer layers of the sclera (¾ of its thickness) located in the projection of the flat part of the ciliary body, multiple slit-like cavities and enlargements (stretching) of interfiber spaces were revealed with simultaneous compaction of the inner part of the sclera (» of its thickness). CONCLUSION: The identified morphological changes may indicate certain differences in the mechanisms of intraocular pressure (IOP) reduction after MP-TSCPC and LASH. The results of this study suggest that the enhancement of uveoscleral outflow of intraocular fluid and the hypotensive effect after MP-TSCPC may be associated with laser-induced expansion of the interspaces between the anterior connective tissue fibers of the CB in the suprachoroidal space. With LASH, the possible mechanism of lowering IOP may be related rather to an increase in transscleral filtration due to the appearance of slit-like interfiber spaces in the sclera, caused by local contraction of scleral fibers in the area of laser exposure. The absence of pronounced destructive changes at the histological level indicates the gentle nature of both laser techniques and the possibility of expanding the indications for the use of LASH in the treatment of glaucoma, including at its earlier stages.

RESUMEN

Congenital subluxation of the lens as a complication of Marfan syndrome, Weill-Marchesani syndrome, microspherophakia, etc. leads to the development of amblyopia and requires timely surgical treatment with removal of the subluxated lens and implantation of an artificial intraocular lens (IOL). IOL implantation in children with pathology of the ligamentous apparatus of the lens remains an urgent problem of ophthalmic surgery due to the lack of a consensus regarding the IOL fixation method among practitioners. PURPOSE: This study evaluated the effectiveness and safety of IOL implantation with transscleral fixation using the knotless Z-suture technique in pediatric patients with congenital lens subluxation. MATERIAL AND METHODS: The study included 24 children (36 eyes) with grade III congenital subluxation of the lens who underwent phacoaspiration of the subluxated lens with IOL implantation with transscleral fixation using the knotless Z-suture performed in the Kazakh Research Institute of Eye Diseases in Almaty in the period from 2017 to 2021. The average observation period was 31.7±11.3 months (2.0 to 4.5 years). The stability of the IOL position, the state of the intrascleral sutures, visual acuity after surgery, the presence and severity of complications in the long-term period were evaluated. RESULTS: All patients (100%) had a significant improvement in visual acuity after surgery. No intraoperative complications were registered in any of the cases. Postoperative complications were noted in 8.3% of cases (n=3). The final functional outcome of surgical treatment depended on the presence of concomitant pathology, the main cause of low vision was the development of refractive amblyopia due to refractive errors. CONCLUSIONS: The presented technique of transscleral fixation of IOL has proven to be reliable, which is especially important for pediatric patients considering their high physical activity and expected lifespan.

RESUMEN

This retrospective study aimed to compare the outcomes of modified double-flanged sutureless scleral fixation versus sutured scleral fixation. Medical records of 65 eyes from 65 patients who underwent double-flanged scleral fixation (flange group) or conventional scleral fixation (suture group) between 2021 and 2022 were reviewed. Visual and refractive outcomes, as well as postoperative complications, were compared 1, 2, and 6 months after surgery. We included 31 eyes in the flange group and 34 eyes in the suture group. At 6 months postoperatively, the flange group showed better uncorrected visual acuity (0.251 ± 0.328 vs. 0.418 ± 0.339 logMAR, P = 0.041) and a smaller myopic shift (- 0.74 ± 0.93 vs. - 1.33 ± 1.15 diopter, P = 0.007) compared to the suture group. The flange group did not experience any instances of iris capture, while the suture group had iris capture in 10 eyes (29.4%; P < 0.001). In the flange group, all intraocular lenses remained centered, whereas in the suture group, they were decentered in 8 eyes (23.5%; P = 0.005). The double-flanged technique not only prevented iris capture and decentration of the intraocular lens but also reduced myopic shift by enhancing the stability of the intraocular lens.

RESUMEN

PURPOSE: To report the long term visual outcomes and complications with use of the novel CM-T Flex scleral fixated intraocular lens (CMT-SFIOL). MATERIALS AND METHODS: 116 eyes that underwent CMT-SFIOL were reviewed and 57 eyes with CMT-SFIOL that completed a 2-year follow-up were included. Main outcome measures noted were best-corrected visual acuity (BCVA) and complications. Postoperatively, follow-ups were done at 1 week (1w), 1 month (1 m), 1 year (1y) and 2-year (2y) intervals. RESULTS: 40 (70.17%) of 57 eyes received CMT-SFIOL for surgical aphakia. Mean follow up was 39.77 ± 8.44 months. BCVA for distance & near improved from 1.26 ± 0.84 to 0.76 ± 0.77, 0.50 ± 0.72 and 0.51 ± 0.73 & 1.28 ± 0.58 to 0.98 ± 0.49, 0.92 ± 0.44 and 0.89 ± 0.40 at 1 m, 1y and 2y respectively (p < 0.001 for all). At 1w, 10 eyes (17.54%) had corneal edema (CE) and 8 eyes (14.03%) had anterior chamber (AC) reaction. Two eyes (3.50%) had IOP > 30 mm Hg and 1 eye (1.75%) had vitreous hemorrhage (VH). At 1 m, 3 eyes (5.26%) had CE and 5 eyes (8.77%) had AC reaction. Two eyes (3.50%) had IOP > 30 mm Hg and 1 eye (1.75%) had VH. Cystoid macular edema was noted in 3 eyes (5.26%). At 1y and 2y, 2 eyes (3.5%) and 1 eye (1.75%), had CE. No decentration, dislocation, haptic exposure or retinal detachment was noted. No eyes required resurgery. CONCLUSION: CM-T Flex SFIOL is an effective method to correct aphakia, with reliable and safe long-term results.
