Participant gender:
All
Summary
This controlled, randomized, double blind, multicenter study will be carried out to demonstrate that the topical ophthalmic nanoemulsion of difluprednate 0.05% (Tolf®, Poen Laboratories), has a high anti-inflammatory efficacy, which would allow it to be administered after cataract surgery 1 drop, twice a day , starting the day before surgery and continuing for 14 days and 1 drop, once a day for the following 2 weeks, achieving an adequate anti-inflammatory activity, with the benefit of reducing the toxicity on the ocular surface, improving the dosage and adherence to treatment. The follow-up time will be 28 days and the outcome measures will be evaluated in a baseline (time 0), on day 1, on day 4 and on day 28 after surgery. The active control will be prednisolone acetate 1% + phenylephrine hydrochloride 0.12% topical ophthalmic suspension (Prednefrin® Forte, Allergan Argentina) given 1 drop, 4 times a days and 1 drop, twice a day for the next 2 weeks. Corneal thickness, central macula thickness, endothelial cell count, intraocular pressure, visual acuity, anterior chamber clearance and lacrimal film recovery will be evaluated.
