ABSTRACT
Purpose@#To evaluate the long-term results of Boston type-I keratoprosthesis implantation in Korea. @*Methods@#Medical records of six patients (six eyes) who underwent Boston type-I keratoprosthesis implantation between August 2018 and November 2019 were retrospectively reviewed for more than 36 months. @*Results@#The mean follow-up period was 44.3 ± 7.0 months. Best corrected visual acuity (BCVA) improved significantly for all six eyes, from 2.33 ± 0.51 logarithm of the minimum angle of resolution (logMAR) to 0.67 ± 0.59 logMAR. The vision recovered immediately after the surgery in all patients. Retroprosthetic membrane developed in three of the patients, but the visual acuity remained unchanged. Anatomical success was achieved in all six eyes after Boston type-I keratoprosthesis implantation. @*Conclusions@#The long-term analysis of Boston type-I keratoprosthesis implantation showed a faster recovery and improved visual acuity compared with conventional penetrating keratoplasty. Without the use of systemic immunosuppressants, all six eyes showed long-term survival of the Boston keratoprosthesis. Boston type-I keratoprosthesis implantation may be used in patients with recurrent graft failure after keratoplasty. This was the first study investigating the long-term results of Boston keratoprosthesis implantation in Korean patients.
ABSTRACT
Purpose@#To evaluate the reliability and validity of the Cataract-related Visual Function Questionnaire (CVFQ). @*Methods@#A prospective cross-sectional study of 141 cataract patients was conducted from March 2022 to June 2022. The questionnaire was created based on a literature review and advice from an expert panel. This study determined its construct validity, criterion validity, internal consistency, and test-retest reliability. @*Results@#The CVFQ consists of 15 items distributed among five categories: overall visual quality, overall visual function, distance vision, near vision, and glare. In the exploratory factor analysis of validity, the first three principal components explained 77.8% of the variance. The p-values in the Spearman correlation test comparing the pre- and postoperative total CVFQ score and best-corrected visual acuity (BCVA) were 0.006 and 0.004, respectively. In the reliability analysis, Cronbach’s alpha was > 0.9 for internal consistency and the p-values of each subcategory were all significant in the analysis of test-retest reliability. @*Conclusions@#Our results indicate that the CVFQ is useful for measuring the visual quality and visual function of cataract patients in Korea.
ABSTRACT
Purpose@#To study the long-term efficacy and safety of Flexivue Microlens refractive corneal inlays in Koreans for compensation of presbyopia. @*Methods@#Flexivue Microlens inlays were implanted in nine eyes at Samsung Medical Center from October 2015 to February 2018. The follow-up period was 1.95 ± 0.6 years. Pre- and postoperative near/intermediate/distant visual acuity, spherical equivalent, contrast sensitivity, defocus curve, keratometry, and patient satisfaction were evaluated retrospectively. @*Results@#The uncorrected near visual acuity (UNVA) of the operated eye increased significantly to 0.27 ± 0.10 logarithm of the minimal angle resolution (logMAR) after 6 months (p = 0.012). At the last observation, it was 0.32 ± 0.21 logMAR, which improved compared to before surgery, but the difference was not significant (p = 0.127). The binocular UNVA improved significantly to 0.19 ± 0.78 logMAR at 6 months postoperatively (p = 0.017) and to 0.21 ± 0.13 logMAR at the last observation (p = 0.028). There was no difference in the binocular uncorrected distant visual acuity (UDVA) before and after surgery, but the UDVA of the operated eye decreased significantly to 0.38 ± 0.15 logMAR at 6 months postoperatively (p = 0.007) and to 0.32 ± 0.21 logMAR at the last observation (p = 0.012). Satisfaction with near vision improved significantly after surgery; 14.3% of the patients had a score of 4 (good) or higher and 42.9% did not require near-vision glasses. In one case, the inlay was removed after 17 months due to blurred vision. @*Conclusions@#The Flexivue Microlens has a low risk of complications and is a reversible technique. However, the near vision improvement was temporary and distance vision deteriorated. In addition, the Koreans examined had relatively low satisfaction and high spectacle dependence.
ABSTRACT
Purpose@#To report two cases of paraproteinemic keratopathy (PK).Case summary: A 57-year-old man visited the ophthalmology clinic complaining of decreased visual acuity since 1 year earlier. White crystalline deposits were observed on both corneas and the best corrected visual acuity (BCVA) of both eyes was 1.0. After 3 months, the BCVA decreased to 0.8 in the right and 0.6 in the left. Increased corneal deposits were observed. To rule out PK, his medical records were checked. The patient had been diagnosed with lymphoplasmacytic lymphoma 3 years earlier. Diagnosing PK, the patient was referred back to the Hemato-Oncology department. After 3 months of chemotherapy, the corneal deposits decreased and BCVA returned to 1.0. A 69-year-old woman presented complaining of decreased visual acuity for 2 years. The uncorrected visual acuity (UCVA) was 0.4 in the right and finger count at 30 cm in the left. Brown deposits were observed on both corneas and lenses. The serum copper level was elevated. She was referred to the internal medicine department and diagnosed with multiple myeloma. After treatment, the laboratory results returned to normal, but the UCVA decreased to hand motion in the left. A left white cataract was noted and cataract surgery was performed. 1 month postoperatively, the BCVA was 0.9, with no change in the corneal deposits. @*Conclusions@#When there are corneal deposits, we should consider PK in the differential diagnosis. In such cases, systemic treatment is the first line. Therefore, diagnosing and referring PK patients to the internal medicine department is crucial.
ABSTRACT
Purpose@#To report two rare cases of Brown McLean syndrome after cataract surgery in a patient with aphakia.Case summary: (Case 1) A 54-year-old woman with Marfan’s syndrome who had aphakia and peripheral corneal edema after left eye cataract surgery 4 years ago. The patient had an elevated lesion in the peripheral cornea without involving the central cornea, and had symptoms of pain, irritation and tearing. Specular microscopy showed normal endothelial cell density and morphology in the edematous cornea. The peripheral corneal edema improved after use of antibiotics, autoserum eyedrops and 5% NaCl eyedrops. (Case 2) A 61-year-old woman with aphakia in her left eye after bilateral cataract surgery 11 years ago, underwent surgery for a macular hole in both eyes. The patient developed peripheral corneal erosions and edema in the left eye 2 months after the surgery. Specular microscopy showed normal endothelial cell density and morphology. The peripheral corneal edema was static over the years while using 5% NaCl eyedrops and artificial tears, and did not progress to involve the central cornea. @*Conclusions@#Brown McLean syndrome is a rare disease but the possibility should be considered if a patient with aphakia after cataract surgery has peripheral corneal edema for several years.
ABSTRACT
Purpose@#To report two cases of treatment using high-frequency radio wave electrosurgery for corneal neovascularization that recurred after medication and laser photocoagulation attempts.Case summary: (Case 1) A 53-year-old man visited our hospital complaining of corneal opacity. The best-corrected visual acuity in the left eye was 0.6. Lipid keratopathy indicated new inferior vessels. There was no significant change in corneal opacity after medication and laser photocoagulation; however, the recurrence of feeder vessels was observed. Therefore, electrocautery was performed via high-frequency radio wave electrosurgery. Visual acuity, measured 1 month later, improved to 0.9. Over the subsequent 4-year observation period, new vessels did not recur and the corneal opacity decreased gradually. (Case 2) A 23-year-old woman visited complaining of left eye pain. She had undergone laser photocoagulation three times for corneal new vessels. Visual acuity in her left eye was 0.4. Recurrence of new vessels at the upper cornea was observed, and electrocautery was performed. After 2 months, corneal opacity decreased without revascularization, and visual acuity improved to 0.5. @*Conclusions@#In patients with corneal neovascularization, electrocautery using high-frequency radio wave electrosurgery is simple and effective and can reduce corneal opacity and improve vision without complications.
ABSTRACT
Purpose@#To describe current cataract surgery practice patterns and trends among Korean ophthalmologists. @*Methods@#A survey was conducted among members of the Korean Society of Cataract and Refractive Surgery in October 2020. Of the 998 questionnaires, 262 (26.3%) were received for analysis. Data were analyzed using descriptive statistics and compared with those of previous surveys. @*Results@#The largest percentage of respondents (39%) had 11 years of practical experience. The average, median, and mode monthly volumes of cataract surgeries performed by the Korean Society of Cataract and Refractive Surgery members were 31, 20, and 10 cases, respectively. Topical anesthesia was administered by 85% of the respondents. For intraocular lens (IOL) calculations, 96% of the respondents used optical biometry. The proportion of surgeons providing femtosecond laser-assisted cataract surgery increased significantly from 5% in 2018 to 29% in 2020. This increase was accompanied by an increase in the multifocal IOLs. Those who implant multifocal IOL for >10% of their cases increased from 16% (2018) to 29% (2020). Topical nonsteroidal anti-inflammatory drugs were prescribed postoperatively by 76% of the respondents. Most respondents (70%) prescribed these anti-inflammatory drugs for 4 weeks. @*Conclusions@#This survey provided a comprehensive update on current cataract surgery practice in the Republic of Korea. The results highlighted the increasing use of premium IOLs, femtosecond laser-assisted cataract surgery, optical biometry, and topical anesthesia to better meet the patients’ needs.
ABSTRACT
A 62-year-old male with a history of femoro-femoral crossover bypass surgery 31 months previously presented with recurrent symptoms of fever and chills, along with a previous positive blood culture. Computed tomography showed vegetation in the bypass graft located in the peritoneal cavity, closely abutting the small bowel and soft tissue lesions in the right proximal thigh and distal calf. Under high suspicion of graft-enteric fistula with metastatic infection, surgery was performed to remove the previous graft and insert a new femoro-femoral bypass graft subcutaneously. Small bowel resection and anastomosis were also performed because the graft penetrated the small bowel mesentery and eroded into the small bowel.The patient had a patent graft without infection for more than 10 years. This case demonstrates the importance of tunneling in femoro-femoral crossover bypass free from the small bowel or other intraperitoneal organs.
ABSTRACT
Purpose@#Native arteriovenous fistula (AVF) is the first choice for hemodialysis access; however, the maturation failure rate remains high. Hence, balloon-assisted maturation (BAM) is increasingly being used to overcome maturation failure. This study evaluated the outcomes of BAM and compared the differences between radial-cephalic (RC) and brachial-cephalic (BC) AVF. @*Materials and Methods@#Between January 2013 and December 2017, 1,622 new AVFs were created. BAM was considered if the AVF did not satisfy the criteria for hemodynamic maturation (6-mm diameter and 500-mL/min flow rate within 8 weeks after the operation). @*Results@#Of the 1,622 AVFs, BAM was performed in 142 patients (8.75%). There were 92 RC and 50 BC AVFs. Multivariate analyses revealed that ipsilateral central vein catheter history was the sole risk factor for maturation failure after BAM. Oneyear functional primary patency (FPP) and functional secondary patency (FSP) in RC AVFs were higher than those in BC AVFs without statistical significance (FPP, RC vs. BC: 70.9% vs. 50.9%, P=0.099; FSP, 95.5% vs. 81.1%, P=0.146). Further, based on the multivariate analysis, the independent risk factors for FPP in the RC and BC AVFs were the number of BAMs (odds ratio [OR], 3.05; 95% confidence interval [CI], 1.11-8.37; P=0.03) and age (OR, 1.04; 95% CI, 1.00-1.07; P=0.04), respectively. @*Conclusion@#BAM is a relatively good salvage method with tolerable patency. However, the risk factors for patency and the outcomes of BAM differ between RC and BC AVFs.
ABSTRACT
Purpose@#We report the clinical characteristics and the primary underlying diseases of patients at high risk for failure of penetrating keratoplasty (PKP) in Korea. @*Methods@#Patients at high risk of PKP failure among those who visited the ophthalmological clinics of tertiary care hospitals in Korea from April 2019 to April 2020 and who were indicated for PKP were retrospectively enrolled. We epidemiologically investigated 119 eyes of 104 patients via medical chart review. @*Results@#Herpes simplex virus (HSV) keratitis was the most common primary underlying disease (26.1%). The most common primary cause of poor bilateral visual acuity was Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN) (41.7%) followed by chemical burns (19.4%). Of the 119 eyes, 40.3% had a history of previous PKP and 20.2% had undergone three or more PKP. The average number of prior PKPs was 1.02 ± 1.46. Corneal neovascularization and corneal opacity were reported in 82.4 and 92.4% of cases, respectively. As the severity of these conditions increased, the eye distributions became larger. Of all patients, 47.9 and 31.9%, respectively, received the highest corneal neovascularization and corneal opacity scores. @*Conclusions@#Our study of patients at high risk of PKP failure improves our understanding of the relevant clinical characteristics and primary underlying diseases. Such patients require careful observation and aggressive treatment. Possible alternatives to PKP should be considered if PKP consistently fails. This study will aid clinicians in deciding whether to proceed to surgery if a poor postoperative prognosis is predictable.

ABSTRACT
Purpose@#The purpose of this study was to compare corneal astigmatism correction between “wound open” and “wound intact” methods during femtosecond laser-assisted transepithelial arcuate keratotomy. @*Methods@#From April 2016 to December 2018, a retrospective survey was conducted on patients undergoing femtosecond laser cataract surgery at the Ophthalmology Department of Samsung Medical Center. Size comparison and vector analysis of corneal astigmatism before and after surgery were performed in the wound open and wound intact groups. @*Results@#In the wound open and wound intact groups, the target-induced astigmatism (TIA) was 1.28 ± 0.55; and 1.26 ± 0.29 diopters, the surgically induced astigmatism (SIA) was 0.80 ± 0.52; and 0.53 ± 0.32 diopters, and the correction index (CI) was 0.63 ± 0.28; and 0.43 ± 0.26, respectively. The astigmatism correction was superior in the wound open group (p = 0.048, p = 0.025). In a subgroup with TIA 1.2 diopters, the SIA was 1.09 ± 0.59; and 0.54 ± 0.37 diopters and the CI was 0.60 ± 0.28; and 0.36 ± 0.23 in the wound open and wound intact groups, respectively (p = 0.022, p = 0.047). Thus, astigmatism correction was superior in the wound open group. @*Conclusions@#The wound open method during femtosecond laser-assisted transepithelial arcuate keratotomy was superior for astigmatism correction compared to the wound intact method.
ABSTRACT
Purpose@#To investigate the in vitro effect of cyclosporine A (CsA)-induced senescence on human corneal endothelial cells (HCECs). @*Methods@#HCECs were cultured and incubated with 0-100 µM CsA. Senescence-associated β–galactosidase (SA-β-gal) staining was performed. Mitochondrial dehydrogenase activity was assessed using a WST-8 assay kit and mitochondrial membrane potential (∆Ψ m ) was measured using JC-1 dye. Intracellular and mitochondrial formation of reactive oxygen species (ROS) was measured with 2’,7’-dichlorodihydrofluorescein diacetate and MitoSOX probes. Intracellular and mitochondrial calcium levels were measured using Fluo-4 and Rhod-2, respectively. Protein expression was evaluated by Western blotting. @*Results@#CsA increased the percentage of SA-β-gal-positive cells (p = 0.003) and decreased mitochondrial dehydrogenase activity and ∆Ψ m in a dose-dependent manner (p = 0.029, pp = 0.004). Intracellular and mitochondrial ROS levels increased during incubation with CsA (p = 0.005). CsA at 100 µM increased mitochondrial calcium levels (p = 0.001), whereas intracellular calcium levels decreased at 100 µM CsA (p = 0.029). CsA activated GSK3β and ERK1/2 and reduced ZO-1 expression. @*Conclusions@#CsA induces senescence in HCECs through oxidative stress and via mitochondria-, GSK3β-, and ERK1/2-dependent pathways. Thus, concentrations of CsA should be monitored.
ABSTRACT
PURPOSE: To evaluate and compare the efficacy and sensation of instillation between 0.05% cyclosporine nanoemulsion group and microemulsion group. METHODS: This is a double-blind, prospective randomized clinical trial. Patients had 2 weeks of wash-out period before the study. They were randomly assigned to either nanoemulsion group or microemulsion group and treated with each group's cyclosporine eye drop. Artificial eye drop and topical steroid were used together according to severity of dryness of cornea. We checked every patient's Break-up time (BUT), Schirmer test, Staining Score and Ocular surface disease index (OSDI) on baseline, 1 month and 3 months after. Patients also self-checked frequency of use of artificial eye drop and topical steroid. Sensation of instillation was also checked. RESULTS: Both nanoemulsion eye-drop and microemulsion eye-drop improved BUT, Schirmer test, Staining Score and OSDI throughout 12 weeks. The nanoemulsion type reduced OSDI significantly compared to the microemulsion type. The mean frequency of use of artificial tear and topical steroid was similar in both groups. Foreign body sense score was higher in microemulsion group. CONCLUSIONS: 0.05% cyclosporine nanoemulsion type has simillar efficacy and subjectively less foreign body sensation.

PURPOSE: To discuss the clinical course and diagnosis of corneal dysplasia in a xeroderma pigmentosum patient based on a genetic evaluation. CASE SUMMARY: A 42-year-old female visited our clinic for decreased left visual acuity and corneal opacity. She had undergone several surgeries previously due to the presence of basosquamous carcinoma in the left lower eyelid, neurofibroma, and malignant melanoma of the facial skin. The patient showed repeated corneal surface problems, with a suspicious dendritic lesion; however, antiviral therapy was ineffective, and herpes simplex virus polymerase chain reaction results were negative. Despite regular follow-ups, the patient showed neovascularization around the corneal limbus and an irregular corneal surface. We performed corneal debridement with autologous serum eye drops for treatment. The patient's visual acuity and corneal surface improved after the procedure. The impression cytology result was corneal dysplasia. In whole exome sequencing, two pathogenic variants and one likely pathogenic variant of the POLH gene were detected. CONCLUSIONS: This is the first genetically identified xeroderma pigmentosum case with ophthalmological lesions of the eyelid and cornea in Korea. Debridement of the irregular corneal surface and autologous serum eye drop administration in xeroderma pigmentosum could be helpful for improving visual acuity.

PURPOSE: To report a case of bilateral posterior subcapsular cataract after taking oxcarbazepine (Trileptal®, Novartis, Basel, Swiss). CASE SUMMARY: A 19-year-old female visited our clinic with decreased vision in both eyes. Her best-corrected visual acuity was 0.3 in the right eye and 0.5 in the left eye, and slit-lamp examination revealed a bilateral cortical opacity and subcapsular cataract. She had been taking oxcarbazepine for epilepsy for 10 years, which was discontinued 3 years ago. Her mother had undergone cataract surgeries when she was approximately 46 years of age. No other risk factors for cataract were present. CONCLUSIONS: In the present case, bilateral cortical opacity and subcapsular cataract were assumed to be associated with the use of oxcarbazepine. We suggest that oxcarbazepine could induce a cataract and recommend a regular follow-up by a qualified ophthalmologist.
