Purpose To evaluate results of 23-gauge transconjunctival sutureless vitrectomy in various indications of vitreoretinal diseases. Design Prospective, non-comparative study. Materials and methods Fifty-seven consecutive eyes of 57 patients underwent vitreoretinal surgery by one surgeon using the 23-gauge, two-step instrumentation developed by Dutch Ophthalmic Research Center Inc., for epiretinal membranes (n ¼ 24), macular holes (n ¼ 10), diabetic retinopathy (n ¼ 4), rhegmatogenous retinal detachment (n ¼ 3), silicone oil removal (n ¼ 10), and other procedures (n ¼ 4). Mean operative time and intraoperative and postoperative complications were recorded. At 1 month, postoperative visual acuity, anatomical results, and induced astigmatism measured by Orbscan (BAUSCH and LOMB laboratories Inc., Rochester, NY, USA) were analysed. Results Mean operative time was 32.6±21.5 min. At 1 month, mean visual acuity improved from 1.09±0.82 to 0.80±0.79 logMar. Transient postoperative hypotony was the most common complication (21.1%), resolving without treatment. There was no choroidal effusion; and no postoperative endophthalmitis was observed. There were no significant changes in mean keratometry (P ¼ 0.957), mean axis (P ¼ 0.818), and power of astigmatism (P ¼ 0.860) at 1 month. Conclusions A 23-gauge vitrectomy seems to be safe and effective for a wide range of indications for vitreoretinal surgery. Further studies are needed to compare it with 25-gauge and 20-gauge vitrectomy in larger series.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
