Clinical Outcomes of ATOS-mediated SmartSight Lenticule Extraction

Purpose@#To evaluate the clinical outcomes of a new refractive corneal lenticule extraction method (SmartSight) using a Schwind ATOS femtosecond laser (Schwind Eye-Tech-Solutions, Kleinostheim, Germany). @*Methods@#The medical records of 338 eyes of 170 patients who underwent SmartSight treatment from April to September 2022 and were followed-up for at least 3 months were retrospectively analyzed. The patients were followed-up at 1 day, 1 week, and 1 and 3 months after operation. Refraction, visual acuity, and intraocular pressure were measured at each visit. @*Results@#Preoperatively, the uncorrected distant visual acuity was 1.26 ± 0.33 logarithm of minimum angle or resolution (logMAR) and the spherical equivalent was -4.52 ± 1.77 diopters. The 3-month, postoperative, uncorrected distant visual acuity was 0.01 ± 0.03 logMAR and the spherical equivalent was -0.12 ± 0.22 diopters. The 3-month data were as follows: efficacy of refractive surgery, 0.99 ± 0.11; safety, 1.00 ± 0.05; predictabilities at ±0.5 and ± 1.0 diopters, 97% and 100%, respectively. @*Conclusions@#Myopic astigmatism correction using the SmartSight method was effective, safe, and predictable in terms of visual outcomes.

Relationship between Palpebral Fissure Height and Corneal Astigmatism of Epiblepharon

PURPOSE: To study the effect of plapebral fissure height on astigmatism in epiblepharon patients. METHODS: The study consisted of 68 eyes of 34 patients who were diagnosed with epiblepharon and 88 eyes of 44 patients who had normal eyelids from September 2012 to July 2013. Data on palpebral fissure height and refractive errors were compared between the epiblepharon group and the control group. Epiblepharon patients were further divided into two subgroups depending on the degree of preoperative corneal erosion in order to study the effects of corneal erosion on corneal astigmatism. RESULTS: The mean age was 5.6 ± 2.2 years in the epiblepharon group and 6.1 ± 1.5 years in the control group (p = 0.339). The mean astigmatism was 2.28 ± 1.54 D in the epiblepharon group and 0.91 ± 1.07 D in the control group. The epiblepharon group showed higher astigmatism than the control group (p < 0.001). The mean palepebral fissure height was 6.70 ± 1.19 mm in the epiblepharon group and 7.63 ± 1.06 mm in the control group. The epiblepharon group exhibited smaller palpebral fissure height than the control group (p < 0.001). In the palpebral fissure height subgroups of the epiblepharon group, the <7.0 mm group showed higher astigmatism than the ≥7.0 mm group (p = 0.026). Higher astigmatism was associated with smaller palpebral fissure height (p = 0.022). CONCLUSIONS: Patients with epiblepharon had significantly higher corneal astigmatism, and higher astigmatism was associated with smaller palpebral fissure height.

A Study of Ocular Disease and Treatment in Patients with Developmental Disability

PURPOSE: To evaluate ocular abnormalities in children with developmental disability and to find out whether any correlation exists between developmental disability and surgical outcome. METHODS: Totally 43 patients with the diagnosis of developmental disability were enrolled in this retrospective study. RESULTS: Mean follow-up was 4.54 +/- 2.35 year. 20 patients had exodeviation, 15 patients had esodeviation, 10 patients had dissociated vertical deviation and 4 patients had dyskinetic strabismus. 21 patients had surgery and the mean deviation angle was decreased from 36.67 +/- 15.70 PD to 5.33 +/- 5.93 PD in exotropia and 56.25 +/- 8.54 PD to 5.75 +/- 4.65 PD in esotropia. Refractive error was found in 33 patients (88.4%). 26 patients (60.5%) had monocular amblyopia and 17 patients (65.38%) showed improvement of visual acuity after treatment. CONCLUSIONS: Exotropia is the most common type strabismus in patients with developmental disability and dyskinetic strabismus is found in cerebral palsy. Strabismus Surgery for patients with stable angle deviation and amblyopia treatment is effective in children with developmental disability. However decision for surgery should be made after a long follow up period.

A Case of Conjunctival Inclusion Cyst Managed with Marsupialization

PURPOSE: We present a case with conjunctival inclusion cyst at inferior fornix treated by marsupialization. CASE SUMMARY: A 23-year-old woman visited our clinic complaining of left lower eyelid swelling. Ophthalmologic examination and CT scan showed a cystic mass from inferior conjunctival fornix to anterior orbit with shallow fornix and focal symblepharon. The cyst was effectively removed with marsupializaion. Postoperatively, there was no recurrence of cyst and the fornix was deepened. CONCLUSIONS: Marsupialization can be a considerable treatment option in conjunctival inclusion cyst, especially when accompanied by shallow fornix and symblepharon.
