The goal of this study is to evaluate the tolerability of the new formulation of Dorzolamide+Timolol preservative free developed in OSD Aptar Pharma multidose system in comparison with Dorzolamide +Timolol BAK preserved ophthalmic formulation.

The present study will be carried out to evaluate the antiallergic efficacy of Bepotastine besilate 1.5% free of preservatives versus standard treatment with 0.2% Olopatadine hydrochloride with 0.1% benzalkonium chloride as preservative in adult patients diagnosed with allergic conjunctivitis.
The antiallergic efficacy will be evaluated by the reduction of ocular signs and symptoms and by the resolution of non-ocular symptoms (rhinorrhea, congestion, and nasal pruritus), as well as the effect of the preservative and its relationship with the cytotoxicity of the ocular surface. Also will evaluate the safety of both products.

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.
