A Prospective Clinical Study Evaluating Dexycu vs Prednisolone Acetate 1%

Phase 4

Completed

Interventions: Drug: Dexycu intracameral dexamethasone
Drug: Prednisolone Acetate

Brief Summary: This is a post-approval, open-label, randomized, self-controlled prospective clinical study to evaluate the safety and ocular efficacy of Dexycu in controlling postoperative ocular pain and inflammation associated with cataract surgery.

Detailed Description: On initial consultation, each study subject will be randomized by a table in the possession of investigators to receive one of two treatment groups, either experimental or control in the first eye. The second eye will undergo cataract surgery approximately 2 weeks later and will be treated with the other treatment group:

Dexycu Group: A total of 30 study subjects will have Dexycu intracameral dexamethasone placed in their scheduled surgical eye at the time of surgery and will receive 50 micrograms of intracameral moxifloxacin at the conclusion of the procedure. They will take Prolensa each day after surgery for 4 weeks.

Control Group: A total of 30 study subjects will receive topical moxifloxacin 0.5% four times per day 1 day prior to surgery and for ten days postoperatively, Prolensa every day 1 day prior to surgery and for 4 weeks postoperatively, and prednisolone acetate 1.0% four times per day starting at the conclusion of cataract surgery for 2 weeks and twice per day for 2 weeks in their scheduled surgical eye.
