Study of Difluprednate vs. Prednisolone Acetate on Visual Acuity, and Corneal Edema Following Cataract Surgery.

Completed · Phase 4

Conditions studied: Cataracts, Corneal Edema, Retinal Structural Change, Deposit and Degeneration, Visual Acuity Reduced Transiently

In brief

The 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.
