Sub-epithelial gas breakthrough during femtosecond laser flap creation for LASIK.

ABSTRACT:

Introduction

The femtosecond laser produces photodisruption at the molecular level to generate plasma, displacing the surrounding tissue resulting in the formation of cavitation bubbles. We report a case of myopic LASIK in which a vertical gas break through the surface occurred during IntraLase femtosecond flap creation.

Case report

A 30 year-old patient underwent bilateral Wavefront guided (WaveScan, Visx, USA) LASIK. The IntraLase (FS 60) was used to create a 100 microm flap. In the right eye, during flap creation in a raster mode, subepithelial gas breakthrough was noted in two focal areas. The surgeon was able to lift the flap without creating a buttonhole. The excimer ablation procedure was performed and the flap was repositioned. On the first postoperative day uncorrec
