Purpose. To evaluate the effect of diclofenac sodium drops and bandage contact lens (BCL) following photorefractive keratectomy (PRK) on preoperative and postoperative ocular response to light and discomfort. Methods. Seventy-seven eyes of 62 patients undergoing PRK were randomly assigned to the following treatment groups: Group 1- pressure patch, no diclofenac; Group 2- pressure patch, diclofenac; Group 3- BCL; no diclofenac; Group 4- BCL, diclofenac. At baseline (preoperative), and postoperative day I, and day 3-4, patients were evaluated for ocular response to light by a calibrated light source, and the degree of self-reported discomfort by a modified McGill pain questionnaire. Results. At day 1, there was no difference in light sensitivity between all groups but on postoperative day 4, Groups 3 and 4 could tolerate more light than the other groups. Groups 2 and 4 experienced less postoperative discomfort at Day 1. The rate of reepitheliauzation was shorter in groups 3 and 4. Conclusions: BCL improves postoperative light sensitivity, discomfort, and reepithelialization rate. Diclofenac sodium drops reduces discomfort.
