Ring segments, cross-linking improve vision in eyes with post-LASIK corneal ectasia
Intrastromal corneal ring segment implantation combined with corneal collagen cross-linking improved vision and refraction in eyes with corneal ectasia after LASIK, according to a study.The retrospective study included 16 eyes of 14 patients who underwent femtosecond laser-assisted implantation of a KeraRing (Mediphacos) and same-day cross-linking. Primary outcome measures were logMAR uncorrected and corrected distance visual acuity, spherical and cylindrical refraction, and simulated keratometry values. Mean follow-up was 43 months.
