Transepithelial Collagen Cross-linking versus Contact Lens-assisted Collagen Cross-linking for Progressive Keratoconus with Borderline Corneal Thickness: A Prospective Comparative Study
Abstract:Aim:To compare outcomes of transepithelial collagen crosslinking (TECXL) and contact lens-assisted collagen crosslinking (CACXL) for progressive keratoconus with borderline corneal thickness.
Materials and methods:In this prospective, comparative, interventional series, twenty eyes with progressive keratoconus and a preoperative 'epithelium on' minimal corneal thickness (MCT) of 350-420 µm, were randomized to undergo TECXL (n = 11 eyes) or CACXL (n = 9 eyes) using hydroxypropyl methylcellulose (HPMC) based 0.2… Show more
