Comparison of the efficacy of diclofenac and betamethasone following strabismus surgery

AIMS: To compare the relative antiinflammatory potency and safety of topical diclofenac-gentamicin with betamethasone-neomycin following strabismus surgery. METHODS: A single centre, single observer, prospective, randomised, and double masked clinical trial of 25 children undergoing bilateral symmetrical horizontal strabismus surgery was carried out. One eye received diclofenac-gentamicin and the contralateral eye received betamethasone-neomycin; both treatments were instilled four times a day for 4 weeks postoperatively. Ocular inflammation was assessed at 1 and 4 weeks postoperatively, objectively by comparison with a photographic chart and subjectively by questionnaire. RESULTS: There was no statistically significant difference in the rate of resolution of the inflammatory response between each group at both visits. CONCLUSION: Diclofenac appears to be as effective as betamethasone in controlling postoperative inflammation following strabismus surgery and may offer a safer alternative to the use of topical steroids.
