PURPOSE: To compare the outcomes of transconjunctival sutureless 23-gauge vitrectomy and conventional 20-gauge vitrectomy 1 year after removal of preretinal membrane.
DESIGN: Retrospective, consecutive, comparative case series.
METHODS: One hundred consecutive eyes with a preretinal membrane underwent either 23- and 20-gauge vitrectomy. The rate of improvement of the logarithm minimum angle of resolution visual acuity (VA) was calculated by the formula: (various postoperative values-preoperative values) x 100/ (1 year postoperative values-preoperative values).
RESULTS: No significant differences were found between the groups in the preoperative and postoperative VAs. The VA improvement was higher and the surgically induced corneal astigmatism was lower 1 week postoperatively in the 23-gauge group compared with the 20-gauge group (P = .006 and P = .001, respectively). The flare values in the anterior chamber measured by laser flare meter preoperatively and 1 week postoperatively did not differ between the groups. The surgical time was significantly (P = .023) shorter in the 23-gauge group than in the 20-gauge group. No apparent complications developed in either group.
CONCLUSION: Transconjunctival sutureless 23-gauge vitrectomy appears effective for preretinal membrane surgery with an acceptable safety profile. Transconjunctival sutureless 23-gauge vitrectomy may be a treatment option for preretinal membranes.
