A New Corneal Remodeling Technique with Laser Asymmetric Keratectomy Using Semi-Cylindrical Ablation Pattern Reducing Regional Asymmetry of Corneal Thickness, Case Series

Abstract

Laser asymmetric keratectomy using semi-cylindrical ablation pattern (LAK-SCAP) is a new customized corneal remodeling method reducing regional asymmetry of corneal thickness, so could be to avoid and treat conventional laser refractive surgery adverse effects. Three eyes (3 patients) had laser epithelial keratomileusis (LASEK) linked LAK-SCAP (L-LAK-SCAP) to reduce regional asymmetry of corneal thickness and correct refractive errors. On Orbscan map, the cones of the corneas were located in the peripheral side, the corneal thickness imbalance was severe due to the sum of 4 direction differences in corneal thickness >80µm.
