Factors associated with changes in posterior corneal surface following laser-assisted in situ keratomileusis.

Purpose: To identify factors associated with changes in the posterior corneal curvature following laser-assisted in situ keratomileusis (LASIK).

Methods: This retrospective study included myopic astigmatic eyes that underwent LASIK between January and December 2013 at Care-Vision Laser Center, Tel-Aviv, Israel. The average posterior keratometry was measured with the Sirius device at a radius of 3 mm from the center.
