Excimer surface ablation techniques for refractive error correction have become popular, mainly in patients with a possible risk of complications after lamellar surgery. Improvements in the understanding of corneal biomechanics, wound healing modulation, laser technology including ablation profiles and various methods of epithelial removal have expanded the scope for surface ablation. In this review, we describe the preoperative assessment, techniques (photorefractive keratectomy, laser assisted sub-epithelial keratectomy, epithelial laser-assisted in situ keratomileusis), outcomes, and complications of surface ablation techniques. Surface ablation techniques will continue to evolve, with potential improvements in results accompanying future sophisticated ablation profiles and advanced laser technology.Abstract
