Scleral lenses lies on the sclera, not the cornea, and help to improve vision in cases of irregular cornea or ocular surface diseases, and to treat ocular surface diseases with moisture to the cornea. The fitting rate of scleral lenses is increasing due to improvements in scleral lens materials and advancements in anterior segment imaging equipment. In order to successfully fit scleral lenses, it needs to understand the structure and principles of scleral lenses and select appropriate patients. There is no absolute contraindication of scleral lenses, but regular follow‐up is recommended for patients who require caution.

Purpose: To evaluate the cost-effectiveness of cataract surgery for the beginners using intraocular illumination compared to the case of using microscope illumination.Methods: A Markov model was constructed for cost-effectiveness analysis. Hypothetical Korean men and women over 50 years of age were set as a cohort, and cataract surgeons were limited to beginners with less than 2 years of experience. Cataracts were classified as severe cataracts requiring surgery and mild cataracts that did not require surgery. Cataracts was assumed to progress to severe cataracts in 10% of each year. A cost-effectiveness analysis was performed based on the difference in the complications of surgery according to intraocular and microscope illumination. For the cost, data from the National Health Insurance Corporation were used, and a micro cost calculation method was used. In the utility analysis, data from previous studies were used for utility in each cataract and complication status. Sensitivity analysis was performed to evaluate the uncertainty of the results.Results: The surgery using microscope intraocular illumination showed the cost of 3,168,895 won, and the quality-adjusted life years of 16.4 years. The surgery of intraocular illumination showed the cost of 3,200,552 won and the quality-adjusted life years of 16.5 years. the incremental cost-effectiveness ratio of intraocular illumination was 1,675,630 won compared to microscope illumination. In the sensitivity analysis to, the utility of postoperative state without complication had the greatest influence on the results.Conclusions: For beginners with less than 2 years of surgical experience, the incremental cost-effectiveness ratio was 1,675,630 won, which is acceptable in Korea's health care system, when comparing the case of using intraocular illumination to the case of using conventional microscope illumination.

Purpose: The aim of this study was to investigate binocular visual function and ocular fatigue after the use of smart glasses.Methods: A total of 17 healthy volunteers (age range 13-45 years) were examined for ocular fatigue before and after watching videos for 20 minutes with a binocular smart glasses device. Subjective ocular fatigue was evaluated using a Virtual Reality Symptom Questionnaire (VRSQ). Objective fatigue was measured using the high-frequency component of accommodative microfluctuation. Accommodation amplitude was measured using the push-up method. Changes in the spherical equivalent were also measured using an autorefractometer. Strabismus angles were measured at distant (6 m) and near fixation (33 cm) in primary. Contrast sensitivity tests using the Pelli-Robson chart was performed. Accommodative convergence/accommodation (AC/A) ratio was measured by gradient methods.Results: Subjective ocular fatigue, as indicated by the VRSQ scores, significantly increased after using the smart glasses (p = 0.001). The high-frequency component of accommodative microfluctuation increased in both eyes (p < 0.05). Accommodation amplitude was decreased, and temporary myopia was observed in both eyes (all p < 0.05). However, there was no significant increase in general fatigue according to the VRSQ. Parameters including strabismus angle, AC/A ratio, and contrast sensitivity showed no significant differences before and after smart glasses usage (p > 0.05).Conclusions: The increased high-frequency component of accommodative microfluctuation, decreased accommodation amplitude, and elevated ocular fatigue scores measured by the VRSQ indicate a potential association between the use of smart glasses and ocular fatigue. Further investigations are warranted to explore methodologies for mitigating ocular fatigue and elucidating the potential risk of temporary myopic shifts arising from the utilization of smart glasses.

Rigid gas permeable (RGP) contact lenses are made of materials with excellent oxygen permeability and wettability, so they not only improve oxygen permeability compared to existing lenses, but also provide correction of refractive errors and improved vision in irregular corneas such as keratoconus. However, the hard material of the lens along with hypoxia and hypercapnia of the cornea caused by wearing RGP contact lenses cause various physiological changes in the cornea. Physiological changes in the cornea that may occur when wearing RGP contact lenses include mucin balls, decreased corneal epithelial thickness and increased size, decreased epithelial barrier function, corneal erosion and staining, decreased keratocyte density, decreased corneal sensitivity, and stromal opacities, contact lens‐induced peripheral ulcers, endothelial blebs, increased endothelial polymegethism, and changes in corneal shape. It is necessary to know the performance of the RGP contact lenses being prescribed, be aware of the physiological changes in the cornea caused by wearing RGP contact lenses, and provide the correct lens prescription along with appropriate education to the patient.

Purpose: To compare the clinical outcomes of one-piece aspheric intraocular lens in the patient group with mild zonule weakness and control group.Method: Among the patients who underwent cataract surgery since 2017, 30 patients (average age of 68.26 ± 8.99 years, 14 men, 16 women) and 35 eyes were selected. Prior to surgery, information on LOCS staging, endothelial cell count, intraocular pressure, axial length, and corneal refractive index were analyzed retrospectively. The average follow-up period after surgery was 3 months. The absolute value of the difference between the spherical equivalent value and the target refractive value in the patient group and the control group at 1 month and 3 months after surgery was compared.Results: The absolute value of the difference in refractive value after 1 month in the patient group was found was 0.61 ± 0.41 Diopters and 0.51 ± 0.42 Diopters in the control group, showing no statistically significant difference (p > 0.05). After 3 months, the absolute value of the refractive value difference was 0.46 ± 0.27 Diopters in the patient group and 0.46 ± 0.32 Diopters in the control group, indicating no statistically significant difference (p > 0.05).Conclusions: The one-piece aspheric intraocular lens enVista MX60 does not show statistically significant clinical difference in the difference between the postoperative refractive value and the target refractive value in the patient group, so it may be actively considered for use in the patient with mild zonule weakness.

Purpose: To report a case of corneal ulcer caused by Stenotrophomonas maltophilia monomicrobial infection in an otherwise healthy patient, devoid of underlying medical conditions or predisposing factors.Case summary: A 48-year-old male patient, who was normally healthy without a history of systemic disease, eye trauma, and eye surgery, presented with acute left eye pain that had manifested one day prior. Ophthalmic examination revealed conjunctival injection, corneal edema, and localized corneal ulceration in the left eye. Suspecting infectious keratitis, diagnostic procedures including gram staining, bacterial and fungal cultures, and antibiotic susceptibility testing were promptly instituted. Bacterial culture identified S. maltophilia, prompting an eight-week course of topical gatifloxacin therapy. The subsequent clinical course exhibited improvement, with lingering corneal haziness and the restoration of visual acuity to 1.0.Conclusion: The case featuring the single detection of S. maltophilia, known to cause hospital-acquired opportunistic infections, emphasizes the importance of culture and antibiotic susceptibility testing in the treatment of keratitis. Remarkably, in a patient with a normal immune status and in the absence of factors predisposing to S. maltophilia infections, there were no discernible causative factors damaging the ocular surface environment.

Purpose: To report one case of Posner-Schlossman syndrome following after strabismus surgery.Case summary: A 21-year-old male patient with a previous history of scleral buckling due to rhegmatogenous retinal detachment in right eye, underwent left lateral rectus muscle recession and medial rectus muscle resection surgery for the intermittent exotropia. He complained of blurred vision and pain in the left eye starting from the day after the surgery. When he visited the clinic on the fourth day post-surgery, his best corrected visual acuity was 20/50 and intraocular pressure was 44 mmHg in the left eye. Slit lamp examination revealed corneal edema, 2+ anterior chamber cells, deep anterior chamber, and an open angle in the left eye. After treatment with antiglaucoma eyedrops and steroid eyedrops, the intraocular pressure decreased to 13 mmHg. There were no signs of recurrence during the two-month follow-up period.Conclusions: Posner-Schlossmann syndrome, which occurs after strabismus surgery, must be diagnosed early and treated immediately.

To date, scleral contact lenses have been known only as large-sized contact lenses with an uncomfortable fit, intended exclusively for patients with severe ocular surface diseases. However, with the recent introduction of scleral contact lenses ranging from 14 to 16 mm, designed considering the corneal and eyelid shapes of Asians, it has become possible to prescribe scleral contact lenses for a broader range of corneal disease patients. Patients with severe ocular surface diseases, keratoconus, and irregular astigmatism post-corneal transplantation have shown visual improvement after wearing scleral contact lenses. In this review article, we aim to discuss scleral contact lenses, including their indications and fitting methods.

Purpose: To compare preoperative refractive power estimation and actual postoperative refraction after combined silicone oil removal and intraocular lens (IOL) sulcus implantation in silicone oil-filled aphakic eyes.Methods: Records of patients with silicone oil-filled aphakic eyes who received simultaneous silicone oil-removal and IOL sulcus implantation (Group1) and aphakic patients who received vitrectomy combined with IOL implantation (Group 2) were reviewed. Optical biometry including axial length measurements were obtained using IOL master® 700 and predicted refractive errors, actual postoperative refractive errors were examined retrospectively.Results: Predicted refractive errors, calculated by subtracting 1 diopter (D) from myopic lens power closest to plano based on sulcus implantation, were 0.50 ± 0.12 D in Group 1, 0.45 ± 0.20 D in Group 2. Six months after operation, mean refractive errors measured -0.76 ± 0.49 D in Group 1, -0.23 ± 0.49 D in Group 2, showing significant myopic shift (p < 0.001, p <0.001). Group 1 showed larger significant myopic shift compared to Group 2 (p = 0.001), especially in 3 eyes with insufficient filling of intravitreal silicone oil showing -1.5 D myopic shift.Conclusions: Ocular biometry of silicone oil-filled aphakic eyes undergoing simultaneous silicone oil removal and IOL sulcus implantation are difficult to measure, showing postoperative myopic shift compared to control. Incomplete intravitreal silicone oil filling showed larger refractive errors needing additional compensations.
