Comparison of Refractive Changes Following Pseudophakic Vitrectomy with or without Gas Tamponade

Abstract

To compare refractive changes following 23-gauge (G) vitrectomy with or without gas tamponade in pseudophakic eyes. This retrospective study included patients with neodymium: yttrium-aluminum-garnet (Nd: YAG) laser capsulotomy, who underwent 23 G pars plana vitrectomy (PPV) between February 2015 and March 2019. Indications for surgery included; rhegmatogenous retinal detachment in Group 1 and epiretinal membrane or vitreous hemorrhage (VH) in Group 2. Gas tamponade 12% perflouropropane (C3F8) was used in Group 1 whereas no tamponade was used in Group 2. The minimum follow-up was 24 months for both groups. A total of 47 patients were recruited (Group 1, n=27 and Group 2, n=20). The visual acuity improvement was statistically significant in both groups (p
