DOIAbstract
Aims: This study aimed to evaluate the safety and effectiveness of double contact lens-assisted corneal cross-linking (CXL) in keratoconus patients with very thin corneas. Settings and Design: This is a prospective, interventional, nonrandomized, and noncontrolled case series. Subjects and Methods: Twenty eyes of 15 patients with the corneal thinnest point (CTP) <400 μm were included in the study. Uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), Scheimpflug imaging, and endothelial cell loss were evaluated at baseline and at each study visit. After corneal epithelial debridement, ultrasonic pachymetry was used to measure CTP. Double soft contact lenses were applied while riboflavin was instilled every 2 mi...
