52The purpose of this clinical research study is to investigate the efficacy of predosing patients undergoing cataract surgery with the potent corticosteroid difluprednate ophthalmic emulsion 0.05% compared to prednisolone acetate 1% on corneal edema (swelling), and retinal thickness.
Difluprednate ophthalmic emulsion 0.05%: 29 days total, total of 7 drops prior to surgery, and 3 more following surgery while at the surgery center, then Q2H on day of surgery, then QID for 1 week, then BID for 1 week, then stop.
Prednisolone acetate 1% : 29 days total, total of 7 drops prior to surgery, and 3 more following surgery while at the surgery center, then Q2H on day of surgery, then QID for 1 week, then BID for 1 week, then stop.
