| Sumario: | Aydin Yildirim,1 Hasim Uslu,1 Necip Kara,2 Engin Bilge Ozgurhan21Fatih University, Department of Ophthalmology, Sema Research and Treatment Hospital, Istanbul, Turkey; 2Beyoglu Eye Research and Training Hospital, Istanbul, TurkeyPurpose: To report the effect of wavefront-guided photorefractive keratectomy and corneal collagen cross-linking (CXL) on visual problems after Ferrara ring segment placement.Materials and methods: A 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.Results: Six 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.Conclusion: Wavefront-guided surface ablation and CXL may reduce high order aberrations and glare complaints after intrastromal corneal ring implantation.Keywords: keratoconus, Ferrara ring, corneal collagen cross-linking, corneal wavefront, photorefractive keratectomy |
