INTRASTROMAL CORNEAL RING, ASTIGMATISM
Brief summary
To evaluate the clinical outcomes of intrastromal corneal ring segment (ICRS) implantation to correct keratoconus on eyes with prior refractive surgery.
Detailed description
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. Mean age at the time of ICRS implantation was 30,5 years.
Interventions
PROCEDUREINTRASTROMAL 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.
