Comparison of topical prednisolone acetate, ketorolac tromethamine and fluorometholone acetate in reducing inflammation after phacoemulsification

Abstract

Aims: To compare the efficacy and ocular adverse effects of topical prednisolone acetate, ketorolac tromethamine, and fluorometholone acetate in reducing inflammation after phacoemulsification.

Method: One hundred and twenty eyes were enrolled in a prospective, investigator-masked, randomized controlled trial. Each drug was prescribed 4 times a day for 28 days. The following data were recorded weekly: visual acuity, intraocular pressure, slit lamp biomicroscopy, grading of cells and flare in the anterior chamber, and ocular symptoms.

Results: The number of eyes with a minimal amount of cells in the anterior chamber in the ketorolac group was less than the prednisolone group on day 7 (11:20, p = 0.008) and day 14 (23:31, p = 0.015), and than fluorometholone group on day 7 (11:21, p = 0.011). Intraocular pressure in the prednisolone group was higher than the ketorolac group on day 21 (14.6:12.2 mmHg, p = 0.016). One eye in the prednisolone group had intraocular pressure of 32 mmHg. Burning sensation was reported frequently in the ketorolac group.

Conclusion: All 3 drugs were effective in reducing post-operative inflammation. The efficacy of prednisolone acetate and fluorometholone acetate was comparable. Ketorolac tromethamine showed less efficacy than corticosteroids, however, it did not induce ocular hypertension.
