Pain Management in Corneal Collagen Crosslinking for Keratoconus: A Comparative Case Series.

To compare management of postoperative pain after corneal collagen crosslinking (CXL) with oral gabapentin or ketorolac. Prospective interventional comparative case series in a single center. Patients undergoing epithelium-off (epi-off) or epithelium-on (epi-on) techniques performed by a single surgeon for progressive keratoconus were enrolled and randomly assigned to the ketorolac (10-mg tablets every 8 h) or the gabapentin (300-mg capsules every 8 h) group and instructed to take the medication for the first 3 postoperative days.
