Topical nonsteroidal anti-inflammatory drugs as adjuvant therapy in the prevention of macular edema after cataract surgery

Purpose: The purpose of the study was to assess adjuvant treatment with topical nonsteroidal anti-inflammatory drugs (NSAIDs) (0.9 % bromfenac, 0.1 % nepafenac, 0.5 % indomethacin, or 0.1 % diclofenac) in addition to topical steroidal treatment with 0.1 % dexamethasone and 0.3 % netilmicin for prevention of cystoid macular edema (CME) after uneventful small incision cataract extraction with foldable intraocular lens (IOL) implantation. Setting: Institute of Ophthalmology, Department of Scienze Mediche di Base, Neuroscienze ed Organi di Senso, Aldo Moro University, Policlinico Consorziale di Bari, Bari, Italy. Design: A retrospective 6-month single center study. Methods: Patients were divided into groups according to treatment with topical drugs for 2 weeks, after phacoemulsification with foldable IOL implantation. CME incidence was evaluated by assessing retinal foveal thickness changes using spectral domain optical coherence tomography. All patients were treated with a fixed combination of dexamethasone and netilmicin, and some patients were additionally treated with NSAIDs (bromfenac, nepafenac, indomethacin, or diclofenac). Results: Fourteen patients were treated with bromfenac, 15 with nepafenac, 12 with indomethacin, and 14 with diclofenac; ten patients were treated with dexamethasone and netilmicin alone. At the end of the follow-up, macular thickness, evaluated at 1-week post-surgery, was reduced only in the group treated with nepafenac (−1.3 %, p = 0.048), was increased in the group treated with dexamethasone and netilmicin alone (+4.3 %, p = 0.04), and did not change in the groups treated with bromfenac (−1.1 %, p = 0.3), indomethacin (+0.1 %, p = 0.19), or diclofenac (+1.2 %, p = 0.74). There were no side effects in any group. Conclusions: Topical treatment with nepafenac, bromfenac, and indomethacin enhanced the efficacy of steroids to reduce postoperative macular edema. Diclofenac did not improve steroids efficacy.
