Loteprednol and prednisolone are equally effective for patients undergoing cataract surgery. The 2 topical steroids were comparable on best spectacle-corrected visual acuity (BSCVA) of 20/30 or better at 1 week (100% vs 96.7%) and 1 month (100% vs 100%) after surgery. The study was a prospective multicenter comparative trial to compare the effectiveness of loteprednol 0.5% and prednisolone aceta
