Changes in Corneal Astigmatism Following Pterygium Removal
Abstract: Aims: To investigate the effect of different types of pterygium excision surgery on post operative corneal stigmatism. Setting and Design:-Prospective comparative analysis. Materials and Methods: 240 eyes were considered for pterygium excision. Following pterygiumexcision, these patients underwent 5 different types of surgeries: Conjunctival autograft with sutures (CAG-s) or fibrin glue (CAG-g), conjunctival rotational flap (CRF), or amniotic membrane transplantation with either suture (AMT-s) or with glue (AMT-g). The preoperative and postoperative keratometric measurements were taken using an automated kerato refractometer. Statistical Analysis: The changes in Best Corrected Visual Acuity and astigmatic degree were evaluated using Wilcoxon signed rank test. The difference in a stigmatic values between groups was calculated using one way analysis of variance (ANOVA). Results: The most commonly performed procedure was CAG-s (N = 115), followed by CAG-g (N = 53), CRF (N = 47), AMT-s (N = 15), and AMT-g (N=10). Following surgery, astigmatic values decreased from 3.47 ? 2.50 D to 1.29 ? 1.07 D (P
