Management of pellucid marginal corneal degeneration with simultaneous customized photorefractive keratectomy and collagen crosslinking
Received 10 February 2009; received in revised form 23 March 2009; accepted 24 March 2009.
A 34-year-old woman had simultaneous photorefractive keratectomy and corneal collagen crosslinking with riboflavin–ultraviolet-A irradiation for the treatment of progressive pellucid marginal corneal degeneration in both eyes. No intraoperative or early postoperative complications occurred. Twelve months postoperatively, the uncorrected visual acuity was assessed at 20/40 in both eyes compared with counting fingers preoperatively. The corrected visual acuity also improved from 20/50 and 20/63 to 20/25 and 20/32 in the right eye and left eye, respectively. Corneal topography revealed a significant improvement in both eyes. Despite the encouraging results, longer follow-up is necessary to confirm the stability of the results.
