Overview

Compare manually performed Astigmatic Keratotomy to femtosecond laser astigmatic keratotomy to manage corneal astigmatism more than three diopters after phacoemulsification.

create circumferential corneal incisions, following the limbal curvature, at 1-1.5 mm anterior to the limbus, manually and by using femtosecond laser to correct corneal astigmatism more than three diopters after phacoemulsification.
