Corneal sensitivity decreased in keratoconus patients after corneal cross-linking
Use of corneal cross-linking resulted in reduced corneal sensitivity among patients with progressive keratoconus, according to a study.The prospective, nonrandomized clinical trial included 72 eyes of 36 patients. Cross-linking surgery was performed on one eye, with the other eye used as a control. Corneal tactile sensitivity was analyzed at baseline and at 7, 30, 90 and 180 days after surgery.
