RESUMEN

Diabetic foot complications (DFC) such as ulcers and infection are the leading cause for non-traumatic non-oncologic amputations worldwide with a 5-year mortality reaching 70 %. Every attempt is warranted to preserve the limb for physical and psychological integrity of these patients. When possible to perform, conservative surgeries could save the foot and its function. This review will focus on those procedures that do not require in-depth surgical or microsurgical skills and that could be performed by general orthopedic surgeons. Along with the technical description and specific indication, a literature search was performed to locate the evidence in relation with the efficacy of these procedures. The procedures could be described in 3 categories: bony surgeries, soft tissue procedures and orthoplastic techniques. The bones surgeries include resection arthroplasty, metatarsal osteotomy, internal pedal amputation, distal Symes amputation, cement augmentation and partial or total calcanectomy. Soft tissue procedures include Achilles tendon lengthening, gastrocnemius recession, toe flexor tenotomy and tendon transfer. The reconstructive/orthoplastic techniques include skin grafting, local flaps, fillet flap and regional flaps, mainly the reverse sural flap. Though most of these conservative surgeries have been shown to yield good to excellent results, the indication for each surgery could be confusing. The role of the orthopedic surgeon is fundamental for the optimal treatment of DFC. Though most procedures are easy to learn and to perform without the need of extra surgical skills, mastering indications is key for successful outcomes. In addition, the knowledge of these limb preserving techniques could be paramount in rural areas or if no foot and ankle surgeons are available.

RESUMEN

INTRODUCTION: The routine assessment of intraoperative margins has long been the standard of care for oral cavity cancers. However, there is a controversy surrounding the best method for sampling surgical margins. The aim of our study is to determine the precision of a new technique for sampling tumor bed margins (TBMs), to evaluate the impact on survival and the rate of free flap reconstructions. METHODS: This retrospective cohort study involved 156 patients with primary cancer of the tongue or floor of the mouth who underwent surgery as initial curative treatment. Patients were separated into 2 groups: one using an oriented TBM derived from Mohs' technique, where the margins are taken from the tumor bed and identified with Vicryl sutures on both the specimen and the tumor bed, and the other using a specimen margins (SMs) driven technique, where the margins are taken from the specimen after the initial resection. Clinicopathologic features, including margin status, were compared for both groups and correlated with locoregional control. Precision of per-operative TBM sampling method was obtained. RESULTS: A total of 156 patients were included in the study, of which 80 were in TBM group and 76 were in SM group. Precision analysis showed that the oriented TBM technique pertained a 50% sensitivity, 96.6% specificity, 80% positive predictive value, and an 87.5% negative predictive value. Survival analysis revealed nonstatistically significant differences in both local control (86.88% vs 83.50%; P = .81) as well as local-regional control (82.57% vs 72.32%; P = .21). There was a significant difference in the rate of free flap-surgeries between the 2 groups (30% vs 64.5%; P < .001). CONCLUSION: Our described oriented TBM technique has demonstrated reduced risk of free flap reconstructive surgery, increased precision, and similar prognostic in terms of local control, locoregional control, and disease-free survival when compared to the SM method.

RESUMEN

OBJECTIVE: Head and neck cancers (HNCs) have increased in prevalence and often require free-flap reconstruction (FFR) after tumor ablation. Postoperative complications following FFR can be high, occurring in as many as 48% and 71% of cases. HNC patients also have many disparities in Social Determinants of Health (SDOH), but the potential impact of SDOH disparities on postoperative complications following FFR has not been formally assessed. STUDY DESIGN: Retrospective cohort review. SETTING: Academic Tertiary Care Institution in Northeast United States. METHODS: Patients that underwent head and neck FFR between January 2018 and December 2021 were analyzed to determine associations between quartiles of the national Area Deprivation Index (ADI), a proxy for SDOH disparity, and various medical and surgical postoperative complications. Associations were assessed using χ2 analysis. RESULTS: Two hundred four patients were included in the study, and 61 patients had 97 complications. Significant associations between higher national ADI quartile and incidence of several postoperative complications were identified, including any surgical complication (P = .0419), wound dehiscence (P = .0494), myocardial infarction (MI) (P = .0215), and sepsis (P = .0464). CONCLUSION: There are significant associations between SDOH disparities and postoperative surgical complications, wound dehiscence, MI, and sepsis following head and neck FFR. Addressing SDOH disparities in HNC is pivotal to enhance postoperative outcomes and promote holistic patient care.

RESUMEN

Introduction: Radiation therapy, a standard postoperative treatment for breast cancer, can lead to chronic ulcers owing to compromised tissue healing. Accordingly, flap surgery using healthy tissues is essential for aesthetic and functional recovery. Although various flap techniques exist, each has its own drawbacks. This study introduces the vertical muscle-sparing latissimus dorsi flap as a superior alternative due to its comparative operative efficiency and tissue preservation. Case report: Two female patients aged 60 and 59 years with histories of breast cancer in their left breast treated with radiotherapy presented with chronic ulcers. The first patient had a 4 × 5 cm defect infiltrating the pleural space, while the second had a 15 × 9 cm defect after thoracic surgery for a bronchopleural fistula. In both cases, debridement was followed by reconstruction using a vertical muscle-sparing latissimus dorsi flap, thereby avoiding the need to change the patient's position and repeated draping during surgery. Both patients showed good postoperative recovery without significant complications. Results: The vertical muscle-sparing latissimus dorsi flap resulted in better adhesions and functional outcomes due to shorter surgical duration. Conclusion: The vertical muscle-sparing latissimus dorsi flap is an effective and efficient method for reconstructing radiation-induced chest wall ulcers in patients with breast cancer. Its application in the presented cases highlights its potential as a preferred option in similar clinical scenarios.

RESUMEN

BACKGROUND AND PURPOSE: Retaining partial keloid skin to make cross flaps (keloid-cross-flap surgery) is a modification of the core excision. This study aimed to compare the effectiveness of superficial radiotherapy versus compression therapy after keloid-cross-flap surgery. MATERIALS AND METHODS: In this prospective cohort study, auricular keloid patients were consecutively screened from January 2019 to December 2021. They underwent keloid-cross-flap surgery and then enter either the superficial radiotherapy or the compression treatment group. The primary outcome was the one-year keloid recurrence rate. Secondary outcomes included: non-completion rate of adjuvant treatment; Patient and Observer Scar Assessment Scale (POSAS) scores and auricular aesthetics scores, evaluated by a four-point Likert scale (1 = poor to 4 = excellent) of non-recurring patients. Propensity score matching (PSM) was used to eliminate potential confounding factors. RESULTS: 123 patients were included in the superficial radiotherapy group and 128 in the compression treatment group. Non-completion rate was significantly higher in the compression treatment group (17.97 %), while the loss rate was comparable between the two groups. Overall, 13 patients (13.54 %) relapsed in superficial radiotherapy group, while 22 patients (25.58 %) in compression group (p < 0.05). After PSM, 59 patients in each group were analyzed, and the recurrence rate was lower in the superficial radiotherapy group (13.56 %). Of relapse-free patients, no significant difference was found in PSAS scores, OSAS scores or aesthetic scores between the two groups. CONCLUSION: Keloid-cross-flap surgery could provide favorable morphologic repair of the auricular keloid, and postoperative superficial radiotherapy shows higher compliance and lower recurrence rate comparing to compression treatment.

RESUMEN

Objective: To assess the diode laser-assisted periodontal flap surgery's clinical effectiveness and postoperative pain management in treating chronic periodontitis, and to offer evidence-based medical justification for the procedure's clinical use. Data sources and study selection: In this study, a computer combined with manual search was used to search for articles on diode laser-assisted periodontal flap surgery for the treatment of chronic periodontitis published from the establishment of the database to September 2023. The databases searched included China Academic Journal Full Text Database (CNKI), China Biomedical Literature Database (CBM), Chinese Science and Technology Journal Database (VIP), Wanfang Database, PubMed, Web of science, Cochrane Library, Embase, and Scopus. Two researchers independently performed the screening and study selection, following the inclusion and exclusion standards to extract basic information and required data. Meta-analysis of the included literature was performed using Revman V5.4 software. Result: Thirteen articles were analyzed. Meta-analysis showed that the use of the diode laser was effective in reducing patients' probing pocket depth (PPD) at 3 and 6 months postoperatively (3 months: MD = -0.46, 95 % CI = [-0.89, -0.03], P = 0.04; 6 months: MD = -0.35, 95 % CI = [-0.63, -0.06], P = 0.02), was able to effectively improve 3 month clinical attachment level (CAL) (MD = -0.36, 95 % CI = [-0.66, -0.06], P = 0.02), and was able to promote wound healing and reduce patients' early postoperative pain (MD = 0.67, 95 % CI = [0.01, 1.32], P = 0.05; MD = -1.67, 95 % CI = [-2.23, -1.00], and P < 0. 001), while for gingival index (GI), the use of diode laser did not have a significant effect. Conclusions: The available evidence suggests that the use of a diode laser adjunct is effective in reducing PPD, improving CAL, promoting wound healing, and reducing early postoperative pain in patients compared with flap application alone; however, for GI, diode lasers did not show any improvements. Clinical significance: Periodontal flap surgery fails to eliminate microorganisms from the soft tissue wall, potentially leading to recolonization, reinfection, and accompanying side effects such as pain and swelling. The use of a diode laser reduces PPD, improves CAL, and relieves early postoperative pain.

RESUMEN

Ultrasound has revolutionized reconstructive microsurgery, offering real-time imaging and enhanced precision allowing for preoperative flap planning, recipient vessel identification and selection, postoperative flap monitoring, and lymphatic surgery. This narrative review of the literature provides an updated evidence-based overlook on the current applications and emerging frontiers of ultrasound in microsurgery, focusing on free tissue transfer and lymphatic surgery. Color duplex ultrasound (CDU) plays a pivotal role in preoperative flap planning and design, providing real-time imaging that enables detailed perforator mapping, perforator suitability assessment, blood flow velocity measurement, and, ultimately, flap design optimization. Ultrasound also aids in recipient vessel selection by providing assessment of caliber, patency, location, and flow velocity of recipient vessels. Postoperatively, ultrasound enables real-time monitoring of flap perfusion, providing early detection of potential flap compromise and improved flap survival rates. In lymphatic surgery, ultra-high frequency ultrasound (UHFUS) offers precise mapping and evaluation of lymphatic vessels, improving efficacy and efficiency by targeting larger dilated vessels. Integrating ultrasound into reconstructive microsurgery represents a significant advancement in the utilization of imaging in the field. With growing accessibility of devices, improved training, and technological advancements, using ultrasound as a key imaging tool offers substantial potential for the evolution of reconstructive microsurgery.

RESUMEN

BACKGROUND: In reconstructive surgery, improvements are needed in the effective teaching of free flap surgery. There is a need for easily accessible and widely available training without high financial costs or ethical concerns while still providing a realistic experience. Our aim was to develop an appropriate training model for microvascular flaps. METHODS: We identified pig head halves as most appropriate regarding availability, cost, and realism. These accrue largely by the food industry, so no animals need to be sacrificed, making it more ethical from an animal welfare perspective. We evaluated the suitability as flap donor site and analyzed the vascular anatomy of 51 specimens. RESULTS: Anatomical evaluation revealed a reliable and constant vascular anatomy, allowing the design of a flap model that can effectively illustrate the entire process of microvascular flap surgery. The process was divided into 6 key steps. The flap can be harvested after marking the vascular pedicle 5.3 cm from the lateral corner of the mouth. Skin island design and subsequent tissue dissection follow until a fasciocutaneous flap is raised, similar to a radial flap. Upon completion of flap harvesting, it can be freely transferred for defect reconstruction. Microvascular anastomosis can be performed on recipient vessels in the cervical region, and the difficulty can be individually adjusted. CONCLUSIONS: The developed training model is a reasonable compromise in terms of surgical realism, availability, didactic value, and cost/time effectiveness. We believe it is a powerful and effective tool with high potential for improving surgical education and training.

RESUMEN

Background and objective The objective of this study is to evaluate and compare the surrogate and true end points following surgical periodontal therapy using the Oral Health Impact Profile-14 (OHIP-14) questionnaire. Materials and methods The study included a total of 30 participants, comprising 15 males and 15 females aged between 25 and 50 years. All individuals who had undergone periodontal flap surgery for generalized chronic periodontitis at the Department of Periodontology, Saveetha Dental College and Hospitals were included in the study. The OHIP-14 questionnaire was used to assess the patient-centered outcomes (true end points) pre- and post-flap surgery at baseline and six months. Surrogate end points such as the clinical attachment level (CAL), probing pocket depth (PPD), and gingival index (GI) were recorded at baseline and six months pre- and post-flap surgery. Results Clinical parameters such as the GI (p=0.03*), CAL (p=0.03), and PPD (p=0.02*) showed a statistically significant improvement after surgery. Patient-centered outcomes showed statistically significant differences in terms of taste perception, reduction in pain sensation, improvement in self-consciousness and reduction in anxiety levels, diminution of the feeling of embarrassment and enhancement in the ability to relax due to problems associated with gums, and improvement in the workplace (p<0.05) post-operatively. Conclusion Surgical periodontal therapy plays a pivotal role in improving oral health-related quality of life (OHRQoL) among patients with chronic periodontal disease. Utilizing OHIP-14 as an assessment tool enables a comprehensive evaluation of treatment outcomes, encompassing various dimensions of oral health impact. Patient-centered outcomes such as psychological discomfort and functional limitations can be achieved only by an interdisciplinary approach.

RESUMEN

Tissue expansion is a handy reconstructive technique for the head and neck region; however, its implementation requires careful planning and surgical experience. If tissue expansion is inadequate, forced closure results in wound tension and risks complications, such as postoperative deformity, wide scarring, and wound dehiscence. We report a case of adult forehead melanocytic nevus excision using a tissue expander (TE) where complications caused by insufficient tissue expansion were avoided by creating a flap using a dog ear. The patient was a male in his 20s who underwent surgery with a TE for a congenital melanocytic nevus sized 15 × 10 cm on the left forehead. Resection was performed by tissue expansion using two TEs; however, simple advancement flaps led to excessive wound tension, risk of elevation of the eyebrow on the affected side, and postoperative scarring. Hence, a superficial temporal artery fasciocutaneous island flap with left superficial temporal vessels as a pedicle was raised at the dog ear and moved to the site of strong tension, and the wound was closed without difficulty. Although postoperative laser hair removal was required, both the appearance and functional results were satisfactory. Using anatomical flaps obtained from the surroundings during tissue expansion helps avoid complications associated with forced wound closure.

RESUMEN

Introduction: Head and neck malignancy treatment often involves invasive surgeries, necessitating effective postoperative pain control. However, chronic reliance on opioid medications remains a challenge for many patients after surgery. Multimodal analgesia (MMA) within enhanced recovery after surgery protocols has shown success in limiting narcotic pain medications for other cancer types. In a prior study, MMA comprising acetaminophen, ketorolac, gabapentin, and a neurogenic block reduced opioid use in the 7-day postoperative period for major head and neck reconstructive surgery. This study investigates the impact of multimodal analgesia on opioid prescription and pain during the 6-week postoperative period for patients undergoing major head and neck oncologic surgeries, aiming to understand the longer-term effects of narcotic use. Methods: The study retrospectively examined participants in a [hybrid type 1 effectiveness-implementation pragmatic trial to assess multimodal analgesia's long-term effectiveness in head and neck free flap surgery. Arm A received scheduled acetaminophen and as-needed opioids, while Arm B received scheduled gabapentin, ketorolac, a regional nerve block at the donor site, scheduled acetaminophen, and as-needed opioids. Retrospective data collection included opioid prescription use and pain scores up to 6 weeks after surgery, gathered from the Kansas prescription drug monitoring program, K-TRACS. Results: Thirty patients participated, 14 in Arm A and 16 in Arm B. The average morphine milligram equivalents per day of filled prescriptions were not significantly different between Arm A and Arm B (7.23 vs. 7.88, p = .845). Additionally, average pain scores at 6 weeks showed no significant difference between the two groups (1.4 vs. 1.9, p = .612). Conclusion: Patients with head and neck cancer treated with multimodal analgesia during the perioperative period did not exhibit significant differences in opioid use and pain within 6 weeks after discharge. To confirm these findings, a re-examination with strict measures of opioid use and scheduled pain assessments in a prospective manner is warranted. Level of Evidence: 4.

RESUMEN

INTRODUCTION: To describe the use and technique of a Tenon's transposition flap without overlying conjunctiva to cover bare sclera following bleb excision and tube shunt implantation. PRESENTATION OF CASE: A 76-year-old man with severe stage primary open-angle glaucoma in both eyes presented with a nonfunctioning trabeculectomy with a thin-walled, cystic bleb overhanging the cornea. A Baerveldt-350 Glaucoma Implant in the ciliary sulcus was recommended for further lowering of intraocular pressure, along with concurrent excision of the bleb due to patient dissatisfaction with the cosmesis of the bleb and to prevent future bleb-associated complications. Conjunctiva could be closed without tension over the new tube entry site; however, a defect remained at the prior trabeculectomy site. A Tenon's transposition flap without overlying conjunctiva was created to cover this site. By postoperative week 6, new conjunctiva had grown over the Tenon's transposition graft, appearing as if there had never been a bleb. DISCUSSION: This case illustrates the use of a Tenon's transposition flap to cover bare sclera following bleb excision. This technique proves valuable when conjunctiva is limited, offering an alternative when adjacent conjunctiva cannot be mobilized. CONCLUSION: In cases requiring non-water-tight coverage of bare sclera with limited available conjunctiva, a Tenon's transposition flap can be used, permitting new conjunctiva to safely grow over bare Tenon's. This technique is useful during a variety of scenarios, including tube shunt and trabeculectomy revisions, where conjunctival closure may be difficult.

RESUMEN

Background: Free flap reconstruction for head and neck cancer is associated with a high risk of perioperative complications. One of the modifiable risk factors associated with perioperative morbidity is intraoperative hypotension (IOH). The main aim of this pilot study is to determine if the intraoperative use of goal-directed hemodynamic therapy (GDHT) is associated with a reduction in the number of IOH events in this population. Methods: A before-and-after study design. The patients who had intraoperative GDHT were compared to patients from a previous period before the implementation of GDHT. The primary outcome was the number of IOH episodes defined as five or more successive minutes with a mean arterial pressure <65 mmHg. The secondary outcomes included major postoperative morbidity and 30-day mortality. Results: A total of 414 patients were included. These were divided into two groups. The control group (n = 346; January 1, 2018, to December 31, 2019), and the monitored group (n = 68; January 1, 2020, to May 1, 2021). The median intraoperative administered fluid volume was similar between the control and monitored groups (2250 interquartile range [IQR] [1607-3050] vs. 2210 IQR [1700-2807] mL). The monitored group was found to have an increased use of norepinephrine and dobutamine (respectively, 1.2% vs. 5.9% and 2.4% vs. 30.9%; p < 0.05). When adjusting for confounders (comorbidities, estimated blood loss, and duration of anesthesia) the incidence rate ratio (95% confidence interval) of number of IOH events was 0.94 (0.86-1.03), p = 0.24. The rate of postoperative flap and medical complications did not differ between the two groups. Conclusions: Even though the use of vasopressors/inotropes was higher in the monitored group, the number of IOH episodes and postoperative morbidity and mortality were similar between the two groups. Further change in hemodynamic management will require the use of specific blood pressure targets in the GDHT fluid algorithm.

RESUMEN

OBJECTIVE: The removal of impacted third molars by surgery may occur with a series of complications, whereas limited information about the postoperative pathogenesis is available. The objective of this study is to identify changes in gene expression after flap surgical removal of impacted third molars and provide potential information to reduce postoperative complications. METHODS: The gingival tissues of twenty patients with flap surgical removal of impacted third molars and twenty healthy volunteers were collected for gene expression testing. The collected gingival tissues were used RNA sequencing technology and quantitative real-time PCR validation was performed. DEG was mapped to protein databases such as GO and KEGG for functional annotation and, based on annotation information, for mining of differential expression genes in patients with mpacted third molars. RESULTS: A total of 555 genes were differentially expressed. Among the top up-regulated genes, HLA-DRB4, CCL20, and CXCL8 were strongly associated with immune response and signal transduction. Among the top down-regulated genes, SPRR2B, CLDN17, LCE3D and LCE3E were related to keratinocyte differentiation, IFITM5, and BGLAP were related to bone mineralization, UGT2B17 is associated with susceptibility to osteoporosis. KEGG results showed that the DEGs were related to multiple disease-related pathways. CONCLUSION: This first transcriptome analysis of gingival tissues from patients with surgical removal of impacted third molars provides new insights into postoperative genetic changes. The results may establish a basis for future research on minimizing the incidence of complications after flap-treated third molars.

RESUMEN

OBJECTIVES: Hyperspectral imaging (HSI) provides spectral information about hemoglobin, water and oxygen supply and has thus great potential in perfusion monitoring. The aim of the present study was to investigate the feasibility of HSI in the postoperative monitoring of intraoral free flaps. METHODS: The 14 patients receiving reconstructive head and neck surgery with a radial forearm free flap were included. HSI was performed intraoperatively (t0), on Day 1 (t1), 2 (t2), 3-6 (t3), 7-9 (t4), 10-11 (t5) and 12-15 (t6) postoperatively. Flap tissue perfusion was assessed on defined regions of interest by calculating the perfusion indices Tissue Hemoglobin Index (THI), hemoglobin oxygenation (StO2 ), Near Infrared Perfusion Index (NIR Perfusion Index) and Tissue Water Index (TWI). RESULTS: Image quality varied depending on location of the flap and time of measurement. StO2 was >50 intraoperatively and >40 on t1 for all patients. A significant difference was found solely for TWI between t0 and t2 and t0 and t4. No flap loss occurred. CONCLUSIONS: The use of HSI in the monitoring of intraoral flaps is feasible and might become a valuable addition to the current clinical examination of free flaps.

RESUMEN

OBJECTIVES: This study evaluated the use of lidocaine spray for acute postsurgical pain control after posterior pharyngeal flap surgery. METHODS: Fifty patients aged 4 to 14 years who were scheduled to undergo elective posterior pharyngeal flap surgery were randomized to receive 2.4% lidocaine spray (Group L) or an identical volume of placebo spray (Group C) on the surgical field at the end of the surgery. The primary outcome was the maximum postoperative pain score in the postanesthesia care unit. RESULTS: The maximum pain score in Group L was significantly lower than that in Group C (p = 0.001). The incidence of moderate-to-severe pain in the postanesthesia care unit was significantly lower in Group L than that in Group C (p < 0.001). In the postanesthesia care unit, more patients in Group C were prescribed rescue analgesics (p < 0.001). The time to the first rescue analgesic was also significantly shorter in Group L (p < 0.001). The incidence and maximum score of emergence agitation were lower in Group L than in Group C. Compared with Group C, Group L showed earlier postoperative fluid intake (p = 0.001). Moreover, the score for parental satisfaction with pain control was higher in Group L than in Group C (p < 0.001). CONCLUSIONS: Our findings indicated that the use of 2.4% lidocaine aerosol spray on the surgical site at the end of the surgery could produce good analgesia for acute postoperative pain, reduce the incidence and severity of EA, and shorten the time to restore fluid intake. LEVEL OF EVIDENCE: 2 Laryngoscope, 134:2438-2443, 2024.

RESUMEN

BACKGROUND: In recent years, enhanced recovery after surgery (ERAS) guidelines have been developed to optimize pre-, intra-, and postoperative care of surgical oncology patients. The aim of this study was to compare management outcome of patients undergoing head and neck cancer (HNC) surgery with free flap reconstruction at our institution before and after the implementation of the ERAS guidelines. METHODS: This retrospective study comprised 283 patients undergoing HNC surgery with free flap reconstruction between 2013 and 2020. Patients operated before and after the implementation of the ERAS protocol in October 2017 formed the pre-ERAS group (n = 169), and ERAS group (n = 114), respectively. RESULTS: In the pre-ERAS group the mean length of stay (LOS) and intensive care unit length of the stay (ICU-LOS) were 20 days (range 7-79) and 6 days (range 1-32), and in the ERAS group 13 days (range 3-70) and 5 days (range 1-24), respectively. Both LOS (p < 0.001) and ICU-LOS (p = 0.042) were significantly reduced in the ERAS group compared to the pre-ERAS group. There were significantly fewer medical complications in the ERAS group (p < 0.003). No difference was found between the study groups in the surgical complication rate or in the 30-day or 6-month mortality rate after surgery. CONCLUSIONS: We found reduced LOS, ICU-LOS, and medical complication rate, but no effect on the surgical complication rate after implementation of the ERAS guidelines, which supports their use in major HNC surgery.

RESUMEN

ABSTRACT We present a case of a patient complaining of monocular diplopia due to a decentered ablation after LASIK. The patient underwent a wavefront-guided retreatment, which resulted in an epithelial ingrowth complication. Additionally, the patient developed cataract, with cataract surgery requiring reliable biometric measurements. Therefore, we opted for corneal treatment and corneal surface regularization. Although we attempted to lift the flap and wash the interface initially, the procedure proved unsuccessful, thereby necessitating immediate flap amputation. Once the corneal surface was regularized in the seventh postoperative month, transepithelial photorefractive keratectomy was successfully performed to homogenize the ocular surface, thereby significantly improving the patient's corrected visual acuity and resolving monocular diplopia. The surface and corneal curvature stabilized by the fifth month after the procedure. Phacoemulsification was then performed along with the implantation of a toric monofocal lens, which was selected using an appropriate formula, resulting in an excellent uncorrected visual acuity.
