AIM: To compare the combination of fluorometholone 0.1% and levofloxacin 0.5% to tobramycin/dexamethasone eye drops in controlling inflammation and preventing infection after phacoemulsification with an intraocular lens implantation. METHODS: Sixty eyes from 60 patients undergoing cataract phacoemulsification were randomized into two groups; half of the patients were treated with fluorometholone (6 times/d) combined with levofloxacin (4 times/d), while the other half were treated with tobramycin/dexamethasone (4 times/d) eye drops for one week. Preoperative and postoperative intraocular pressure, aqueous flare, corneal thickness, and signs and symptoms were recorded before the operation and 1wk following treatments. RESULTS: There were no statistically significant differences between the two groups in corneal thickness (P≥0.629), aqueous flare (P≥0.398), and signs and symptoms scores (P≥0.350) at each time point. Ocular hypertension was only observed in two eyes in the tobramycin/dexamethasone group. CONCLUSION: Fluorometholone combined with levofloxacin treatment shows comparable efficacy but without the tendency to increase intraocular pressure; thus, it might be a better regimen for postoperative use.
