Measurement of the Intraocular Pressure Elevation During Laser-Assisted In Situ Keratomileusis Flap Creation Using a Femtosecond Laser Platform

Purpose: The purpose of this study was to measure the intraocular pressure (IOP) elevation during laser assisted in situ keratomileusis (LASIK) flap creation using WaveLight FS200 femtosecond (FS) platform. Methods: We conducted an ex vivo experimental animal model. FS platform used perform corneal LASIK freshly enucleated porcine eyes. measured changes IOP from application suction ring (suctioning phase) through lamellar (cutting phase). recorded a manometric technique with direct cannulation anterior chamber. Results: Nine eyes were included study. mean baseline before procedure 20.33 ± 5.9 mm Hg. increase over 32.33 11.3 Hg at suctioning phase, and 38.22 cutting phase. total surgical time needed complete 29.5 4.4 seconds. Conclusions: produces low moderate creation. Translational Relevance: is safe because it induces
