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

结局指标
主要结局
Intrastromal Corneal Ring Segment Implantation for Ectasia After Refractive Surgery
时间窗: 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.
