The Comparative Efficacy and Tolerability of Diclofenac 0.1% and Bromfenac 0.09% Ophthalmic Solutions after Cataract Surgery

none6noPurpose: To compare the efficacy and tolerability of diclofenac and bromfenac ophthalmic solutions as adjunctive therapy after cataract surgery. Materials and Methods: This prospective randomized controlled study included 130 patients who underwent cataract surgery. One hundred patients were randomized to receive postoperatively diclofenac 0.1% (four times daily for 28 days, Group 1) or bromfenac 0.09% (twice daily for 14 days, Group 2) ophthalmic solutions in addition to steroid-antibiotic combination. Thirty patients instilled only steroid-antibiotic combination (Control Group 3). Laser flare-cell photometry and optical coherence tomography scans with central foveal thickness (CFT) measurement were performed before (V0) and 7 (V1), 14 (V2) and 28 days (V3) after surgery. Treatment tolerability was scored using the Ocular Comfort Grading Assessment. Results: Laser flare-cell photometry values were significantly higher at V1, V2 and V3 compared to V0 in all the groups (respectively 13.3 +/- 1.0, 12.7 +/- 0.9 and 9.6 +/- 0.9 vs 8.4 +/- 0.6 ph/ms for Group 1; 13.4 +/- 1.0, 12.7 +/- 0.9 and 12.7 +/- 1.0 vs 8.1 +/- 0.6 for Group 2; 15.9 +/- 0.8, 15.4 +/- 0.7 and 14.5 +/- 0.7 vs 7.5 +/- 0.5 for Group 3) (p < 0.001); flare increase was significantly lower in Group 1 compared to Groups 2 and 3 (p < 0.001). CFT values were higher after surgery in all the three groups; the increase was significantly lower in Group 1 compared to Groups 2 and 3 (p < 0.0002). The percentage of symptoms-free patients after study treatment was significantly higher in Group 2 compared to Group 1 (respectively 74% vs 14% of the total; p < 0.001). Conclusion: The addition of diclofenac or bromfenac ophthalmic solutions contributed to further reduce both inflammation and cystoid macular edema after cataract surgery compared to steroid-antibiotic combination alone. Diclofenac appeared to be more effective in reducing postoperative intraocular inflammation with a more intense and prolonged regimen, while bromfenac more tolerated with lower daily dose and treatment duration.noneGiannaccare G, Finzi A, Sebastiani S, Greco F, Versura P, Campos ECGiannaccare G, Finzi A, Sebastiani S, Greco F, Versura P, Campos E
