Topical Bromfenac 0.09% vs Ketorolac 0.4% for the Control of Pain, Photophobia, and Discomfort Following PRK

PURPOSE: To compare the efficacy of two topical nonsteroidal anti-inflammatory drugs with regards to the control of pain, burning, photophobia, foreign body sensation, and epithelial healing rates in patients who underwent photorefractive keratectomy (PRK). METHODS: Two hundred twelve eyes were randomized to receive topical postoperative ketorolac 0.4% four times daily (Acular LS, Allergan) or bromfenac 0.09% twice daily (Xibrom, ISTA Pharmaceuticals) in an open label trial. Patients having both eyes treated received ketorolac in one eye and bromfenac in the other. The epithelium was removed using the 8.4-mm Amoils brush (Innovative Excimer Solutions), and various laser beam platforms were permitted for the surgery. Investigated drugs were applied after a bandage contact lens (Acuvue Oasys, Johnson & Johnson Vision Care) was fitted. All patients received postoperative cold saline (balanced saline solution [BSS]), prednisolone acetate 1.0 % (Pred Forte, Allergan), gatifloxacin ophthalmic solution 0.3% (Zymar, Allergan), and in some cases, mitomycin C 0.02% (MMC). Patients recorded postoperative results for pain, photophobia, burning, and foreign-body sensation on a visual linear analog scale. During postoperative follow-up, the corneal epithelial defect was measured. RESULTS: Two hundred twelve eyes from 149 patients were enrolled in the study. Of these eyes, 105 received bromfenac and 107 received ketorolac. No significant differences were noted in postoperative pain, burning, foreign-body sensation, and photophobia between the two drug populations at any time during the study or overall. There were no drug-related adverse events or differences in epithelial healing rates for either drug. CONCLUSIONS: No significant differences were observed between the use of bromfenac (twice daily) and ketorolac (four times daily) with regard to postoperative PRK discomfort and safety when combined with postoperative measures such as cold BSS and a bandage contact lens.
