Interventions

In this retrospective study 8 eyes affected by cornea ectasia of 8 patients (mean age 31.50±14.73 years) underwent simultaneous CCR and CXL. Preoperative and 6 month postoperative uncorrected distance visual acuity (UDVC) and distance corrected visual acuity (DCVA) were measured using the Efficacy and Safety index. Objective and subjective quality of vision were respectively evaluated through preoperative and 6 month postoperative corneal morphological irregularity index (CMI), National Eye Institute Visual Function NEI-VFQ25 and NEI-VFQ39 questionnaires.

Also known as: corneal cross linking
