Comparison of Ketorolac Tromethamine 0.5%-Soaked Bandage Contact Lenses Versus Non-Medicated Bandage Contact Lenses on Postoperative Pain Control After Photorefractive Keratectomy

July 10, 2026 updated by: Hassan Abbas, Madina Teaching Hospital Faisalabad
Photorefractive keratectomy (PRK) is a well-established surface ablation procedure for the correction of refractive errors. Despite excellent visual and refractive outcomes, postoperative pain remains a significant concern, particularly during the first few days following surgery. This pain is primarily related to corneal epithelial removal, exposure of subepithelial nerve endings, and the subsequent inflammatory response. Effective pain management is therefore essential to enhance patient comfort, improve compliance with postoperative care, and increase overall surgical satisfaction. Therefore we will compare postoperative pain levels in patients undergoing PRK using ketorolac tromethamine 0.5%-soaked bandage contact lenses versus non-medicated bandage contact lenses.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Group A Participants who will receive Ketorolac Tromethamine 0.5%-Soaked Bandage Contact Lenses
Group A will receive ketorolac-soaked bandage contact lenses immediately after surgery. Postoperative pain will be assessed using Visual Analogue Scale at defined intervals. Epithelial healing will be monitored clinically until complete re-epithelialization. Any complications arising during postoperative period will be documented for each group.
Soaking Bandage Contact Lenses in ketorolac prior to application may provide sustained drug release at the ocular surface, thereby enhancing postoperative pain control while reducing the need for repeated topical administration.Recent studies have suggested that ketorolac-soaked Bandage Contact Lenses may significantly reduce pain following Photorefractive Keratectomy without adversely affecting epithelial healing
Active Comparator: Group B Participants who will receive Non-Medicated Bandage Contact Lenses
Group B will receive standard non-medicated bandage contact lenses. Postoperative pain will be assessed using Visual Analogue Scale at defined intervals. Epithelial healing will be monitored clinically until complete re-epithelialization. Any complications arising during postoperative period will be documented for each group.
Bandage contact lenses (BCLs) are routinely used after PRK to protect the corneal surface, reduce mechanical irritation from blinking, and promote epithelial healing
