Ocular penetration of moxifloxacin 0.5% and gatifloxacin 0.3% ophthalmic solutions into the aqueous humor following topical administration prior to routine cataract surgery.
A prospective, double-masked, randomized, parallel-group study (n = 25) was conducted to examine the ocular penetration of moxifloxacin 0.5% ophthalmic solution and gatifloxacin 0.3% solution into the aqueous humor following topical administration prior to routine cataract surgery. One drop of antibiotic was instilled every 10 min for four doses beginning 1 h prior to surgery. Preliminary results showed aqueous humor concentrations for moxifloxacin that were significantly greater (p < 0.01) than those for gatifloxacin.
