Intrastromal ring improves distance vision, refractive error in eyes with post-LASIK ectasia
An intrastromal ring improved uncorrected and corrected distance visual acuity and reduced refractive error in eyes with post-LASIK corneal ectasia, according to a study.The prospective study included 15 eyes of 14 patients with post-LASIK ectasia who underwent implantation of a MyoRing (Dioptex). Researchers evaluated logMAR uncorrected and corrected distance visual acuity (UDVA/CDVA), refraction, keratometry, central corneal thickness, corneal biomechanics and corneal aberrometry preoperatively and at 1, 3, 6 and 12 months postoperatively.
