To study the anatomic and intraoperative factors responsible for gas bubble migration in the anterior chamber during femtosecond laser-assisted in situ keratomileusis (FS-LASIK) flap creation.

ABSTRACT:

Purpose

This study investigates the factors responsible for gas bubble migration into the anterior chamber during femtosecond-assisted laser-assisted in situ keratomileusis (FS-LASIK) flap creation.

Methods

A retrospective data analysis was conducted on 20 eyes of 12 patients undergoing bilateral laser-assisted in situ keratomileusis surgery, where intraoperative gas bubble migration was observed. Data from age-matched controls without gas bubble migration were also analyzed. Various preoperative and intraoperative parameters were compared between the groups, including refractive error, keratometry, white-to-white (WTW) distance, angle parameters, anterior chamber depth (ACD), central corneal thickness, flap diameter, pulse energy, suction time, anterior chamber width (ACW),
