Abstract

•Aim: To analyze the changes in central corneal volume (CCV) and endothelial cell density (ECD) using a newer parameter –Volume stress index(VSI) following FLACS compared to PKE.

•Methods: 45 eyes of 45 patients underwent cataract surgery in each group. 3 mm CCV was determined by a rotating Scheimpflug camera (Pentacam HR) and VSI was calculated at 1 day and 1 month postoperatively. ECD was measured by noncontact specular microscopy preoperatively, 1 day and 1 month postoperatively.

•Results: CCV was significantly higher in PKE group as compared to FLACS on day 1 but did not differ significantly at 1 month of follow up. Endothelial cell loss was significantly lower in FLACS on post operative day 1 and 1 month. Gradual decrease in VSI following surgery was seen on both the follow ups in FLACS and PKE.

•Conclusion: FLACS causes less trauma to the endothelial cells as compared to PKE. Hence it results in faster visual rehabilitation than PKE.
