Stability of Simultaneous Topography-Guided Photorefractive Keratectomy and Riboflavin/UVA Cross-Linking for Progressive Keratoconus: Case Reports

Abstract

Partial topography-guided PRK followed by riboflavin/UVA CXL is a safe and effective therapy that halts the progression of keratoectasia and reduces the spherocylindrical refraction and aberrations to improve the visual function of patients with progressive keratoconus. Stability and progressive improvement over time is observed, although limitations may exist for steeper and thinner corneas.
