摘要

PURPOSE: The purpose of this study was to report the outcomes and complications of 25-gauge pars plana vitrectomy for the management of retained lens fragments after complicated cataract surgery. METHODS: This is a retrospective consecutive case series of 17 patients who presented with retained lens fragments, ranging from mostly cortex to the entire lens, which were managed using only 25-gauge instrumentation. RESULTS: Eight men and 9 women (mean age, 73.1 years) were followed for a mean of 4.5 months after 25-gauge vitrectomy for removal of retained lens fragments. Mean preoperative visual acuity was 20/427 and mean final postoperative visual acuity was 20/62. Mean surgical operating time was 48.5 minutes. Mean preoperative intraocular pressure was 24.5 mmHg and mean 1-day postoperative intraocular pressure was 17.9 mmHg. No cases required the use of a phacofragmatome, no sutures were required to close the sclerotomies, and there were no cases of postoperative hypotony. Cystoid macular edema and glaucoma developed postoperatively in 29.4% and 5.9% of eyes, respectively. There were no cases of postoperative retinal detachment or endophthalmitis. CONCLUSION: A 25-gauge vitrectomy technique, without the use of a phacofragmatome, may be a suitable alternative to 20-gauge vitreous surgery using a phacofragmatome in the management of retained lens fragments after complicated cataract surgery. Clinical outcomes and complication rates are comparable to those found in the literature for 20-gauge surgery.
