Clinical Trial: Intrastromal Corneal Ring for Ectasia After Refractive Surgery (Anel)

Study Status: Completed
Recruit Status: Completed
Study Type: Observational

Official Title: Intrastromal Corneal Ring Segment Implantation for Ectasia After Refractive Surgery

Brief Summary: To evaluate the clinical outcomes of intrastromal corneal ring segment (ICRS) implantation to correct keratoconus on eyes with prior refractive surgery.

Detailed Summary: 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.
Sponsor: Instituto de Olhos de Goiania

Current Primary Outcome: Intrastromal Corneal Ring Segment Implantation for Ectasia After Refractive Surgery [ Time Frame: Mean follow-up after ICRS implantation was 12 months (range, 09 to 22 months). ]

To evaluate the clinical outcomes of intrastromal corneal ring segment (ICRS) implantation to correct keratoconus on eyes with prior refractive surgery. 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.


Original Primary Outcome: Same as current
