Changes in Angle Kappa and Corneal Back Elevations After Laser in Situ Keratomileusis in Myopic Astigmatism

December 3, 2023 updated by: Mohamed Elsaiid, Ain Shams University

Refractive errors and corneal astigmatism are associated with changes in angle kappa and corneal back elevation at the thinnest point in Pentacam.

The purpose of this study is to track:

The effect of anterior corneal astigmatism treatment on angle kappa and corneal back elevation.
