简要总结
Compare manually performed Astigmatic Keratotomy to femtosecond laser astigmatic keratotomy to manage corneal astigmatism more than three diopters after phacoemulsification.
详细描述
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.
