INTRASTROMAL CORNEAL RING SEGMENT
Forty-two eyes of 26 patients, 14 men and 12 women, with ectasia after refractive surgery were studied in a nonrandomized, retrospective, observational case series.
INTRASTROMAL CORNEAL RING SEGMENT
Corneal tunnels were created by means of mechanical dissection in all eyes. Main outcome measures included UCVA, BCVA, refraction, keratometry and computerized analysis of corneal topography.
