Management of Corneal Ectasia after LASIK with Phototherapeutic Keratectomy Combined with Photorefractive Keratectomy and Collagen Cross-Linking

<div>Schematic representation of phototherapeutic keratectomy (PTK) combined with photorefractive keratectomy (PRK) and riboflavin with ultraviolet-A collagen cross-linking (CXL) performed sequentially on the same day in the management of corneal ectasia after LASIK. (a) Removal of the epithelium in the previous corneal flap (PTK). (b) Tissue ablation in the previous corneal flap (PRK). (c) Riboflavin with ultraviolet-A collagen cross-linking (CXL).</div>
