Corneal Collagen Cross-linking with Riboflavin and Ultraviolet A Irradiation for Keratoconus: Long-term Results – Corrected Proof
Purpose:
To evaluate the long-term results of corneal collagen cross-linking (CXL) in patients with progressive keratoconus.
Design:
Prospective case series.
Participants:
This study was conducted on 40 eyes of 32 patients with progressive keratoconus between 2006 and 2012.
Methods:
Patients underwent CXL no later than 1 month after baseline examinations. For CXL, ultraviolet irradiation was applied for 30 minutes, during which riboflavin instillation was repeated every 3 minutes.
Main Outcome Measures:
Patients were tested for best-corrected visual acuity (BCVA), uncorrected visual acuity (UCVA), manifest refraction spherical equivalent (MRSE), and Scheimpflug imaging from which we extracted maximum keratometry reading (max-K), average (Read more...)
