Changes of visual acuity before and after operation. The mean BCVA significantly improved after surgery at last follow-up in patients (P = 0.032; t-test) (a). The mean BCVA of D-RPE group was significantly worse than that of the ND-RPE group both before and after surgery (P = 0.019; Wilcoxon signed rank test). BCVA, Snellen best corrected visual acuity; D-RPE, destroyed RPE; ND-RPE, non-destroyed RPE. * P < 0.05 between the two groups
