Corneal keratometric readings were obtained using Oculus Pentacam before surgery, 1 week after, and 1 month after surgery; neither scleral buckling nor silicone oil tamponade were used in order to not affect the final corneal changes. Cases with postoperative hypotony were excluded.Results: The mean preoperative K1 (vertical keratometry) was 44.87 &plusmn; 3.55, the mean preoperative K2 (horizontal keratometry) was 44.57 &plusmn; 3.68; the mean postoperative K1 after 1 week was 45.1 &plusmn; 6.82 while the mean postoperative K2 after 1 week was 45.7 &plusmn; 3.97. Using paired t-test analysis, the P-value of the K1 change was 0.01 and P-value of the K2 change was 0.02. Both indicate minimally significant differences.
