Abstract
PurposeTo report the effect of wavefront-guided photorefractive keratectomy and corneal collagen cross-linking (CXL) on visual problems after Ferrara ring segment placement.Materials and methodsA 32-year-old male patient was treated with a Ferrara ring segment for keratoconus. One year later, the ring was removed due to severe glare complaints. After 6 months, wavefront-guided photorefractive keratectomy and CXL were applied simultaneously to correct high order aberration and refractive error.ResultsSix months after the wavefront-guided photorefractive keratectomy and CXL, the uncorrected distance visual acuity was 20/25, and there was a 30% decrease in coma aberrations. The glare complaint regressed.ConclusionWavefront-guided surface ablation and CXL may reduce high order aberrations and glare complaints after intrastromal corneal ring implantation.
