Abstract

METHODS: Retrospective study

20 patients, 10 in each group, undergoing LASIK surgery for refractive error at our center. Preoperative and intraoperative data including refractive error, keratometry, white to white (WTW) corneal diameter using Pentacam, flap diameter, pulse energy parameters, suction time, angle parameters and anterior chamber depth using CASIA asoct, recorded and compared between the gropus. To determine the anatomical and intraoperative factors, univariate and multivariate logistic regression were used, the eye was unit of analysis.

CONCLUSION: The gas bubble formationin anterior chamber during femtosecond lasik is a common event. The WTW being smaller in Asian eyes predispose them to this complication. The eye anatomy plays a major role in incidence of such event. Pentacam and Casia ASOCT can play a role in predicting such cases in preoperative workup only, acting as an adjuvant technology while planning refractive surgery.
