Eccentric Macular Hole Formation After Macular Hole Surgery

PURPOSE: To report a case of eccentric macular hole formation after surgery for a traumatic macular hole. CASE SUMMARY: A 27-year-old man was admitted to our hospital because of baseball trauma to his left eye. A vitreous hemorrhage and Berlin's edema were found in the macula. One month later, a full thickness macular hole was detected. Vitrectomy and internal limiting membrane (ILM) peeling and gas injection were performed. Two months postoperatively, the primary macular hole was closed, but an eccentric macular hole temporal to the fovea was observed.

Surgically Induced Astigmatism and Corneal Higher Order Aberrations in Microcoaxial and Conventional Cataract Surgery

PURPOSE: To compare surgically induced astigmatism (SIA) and some corneal higher order aberrations in patients who underwent microcoaxial cataract surgery (MCCS) or conventional cataract surgery. METHODS: A prospective randomized study included 60 eyes of 55 patients. Thirty eyes received MCCS using a 2.2mm clear corneal incision (group 1), and 30 eyes received conventional cataract surgery using a 2.8 mm clear corneal incision (group 2). SIA and corneal higher order aberrations were measured with a Keratometer (Humphrey, Zeiss) and i-Trace (Tracey Technologies) preoperatively, and at 1 and 3 months after cataract surgery. SIA was analyzed vectorially using the Alpins method. RESULTS: There was no significant difference in preoperative UCVA or BCVA between the two groups. At 1 month and 3 months after surgery, SIA in group 1 was less than that in group 2, but this difference was not significant. There was no statistically significant difference in postoperative change of corneal higher order aberrations in each group at 1 month or 3 months after surgery, and there was no statistically significant difference in corneal higher order aberrations between the two groups preoperatively, at 1 month, or 3 months after surgery. CONCLUSIONS: There was no significant difference in SIA and corneal higher order aberrations between the two groups.
