Özet
To evaluate the topographic changes of cornea after pars plana vitrectomy (PPV) with the 23-gauge- (23-G) transconjunctival sutureless vitrectomy (TSV) system within the first postoperative month. In this prospective study, corneal topographic changes were evaluated in 24 eyes of 24 patients who underwent PPV with the 23-G TSV system. All eyes underwent computer-assisted videokeratography using NAVIS (Nidek Advanced Vision Information System) software preoperatively and at the first day, first week, and first month postoperatively. The topographic parameters that were analyzed statistically were the average corneal power (ACP), corneal surface cylinder (CSC), surface asymmetry index (SAI), and surface regularity index (SRI). Mean induced astigmatism was estimated by vector analysis software. The Wilcoxon test was used for statistical analysis. Mean ACP was 43.12 ± 1.16 diopters (D) preoperatively and 42.88 ± 1.44 D at first day (P = 0.301), 43.04 ± 1.14 D at first week (P = 0.796), and 43.32 ± 1.17 D at first month postoperatively (P = 0.187). Mean CSC was 0.61±0.32 D preoperatively and 0.71 ± 0.48 D at first day (P = 0.918), 0.60 ± 0.25 D at first week (P = 0.826), and 0.70 ± 0.33 D at first month postoperatively (P = 0.414). Mean SAI was 0.12 ± 0.05 preoperatively and 0.21 ± 0.16 at first day (P = 0.070), 0.15 ± 0.06 at first week (P = 0.176), and 0.16 ± 0.09 at first month postoperatively (P = 0.198). Mean SRI was 0.41 ± 0.37 preoperatively and 1.05 ± 0.41 at first day (P = 0.001), 0.54 ± 0.42 at first week (P = 0.211), and 0.41 ± 0.5 at first month postoperatively (P = 0.861). Mean surgically induced astigmatism was 0.67 ± 0.7 D at first day, 0.36 ± 0.2 D at first week, and 0.33 ± 0.17 D at first month postoperatively. Corneal surface and astigmatic changes were observed to be insignificant in the early postoperative period after PPV with the 23-G TSV system. © 2011 Springer Science+Business Media B.V.
