Abstract

Purpose: To evaluate safety and efficacy of difluprednate 0.05% ophthalmic emulsion for treatment of postoperative inflammation after cataract surgery in pediatric patients. Methods: This was a phase 3B, multicentre, randomized, double-masked, active-controlled study of patients aged 0-3 years who underwent uncomplicated cataract surgery in one eye, with/without intraocular lens implantation. Patients were randomized to receive difluprednate 0.05% four times daily or prednisolone acetate 1% for 14 days post surgery, followed by tapering for 14 days. Safety included evaluation of adverse events. Primary efficacy was the proportion of patients with an anterior cell grade of 0 (no cells) at day 14; secondary efficacy was a global inflammation score. Results: Forty patients were randomized to each treatment group. Adverse drug reactions included corneal oedema (difluprednate 0.5%, n=1; prednisolone acetate 1%, n=0) and increased intraocular pressure or ocular hypertension (n=2/group). Mean intraocular pressure values during treatment were 2-3 mm Hg higher with difluprednate 0.05% compared with prednisolone acetate 1%; mean values were similar between groups by the first week after treatment cessation. At 2 weeks post surgery, the incidence of complete clearing of anterior chamber cells was similar between groups (difluprednate 0.05%, n=30 (78.9%); prednisolone acetate 1%, n=31 (77.5%). Compared with prednisolone acetate 1%, approximately twice as many difluprednate 0.05%-treated patients had a global inflammation assessment score indicating no inflammation on day 1 (n=12 (30.8%) vs n=7 (17.5%) and day 8 (n=18 (48.7%) vs n=10 (25.0%). Conclusions: Difluprednate 0.05% four times daily showed safety and efficacy profiles similar to prednisolone acetate 1% four times daily in children 0-3 years undergoing cataract surgery.
