Prospective Randomized Comparison of Zymar(Gatifloxacin) and Vigamox (Moxifloxacin) in Killing Conjunctival Bacterial Flora Following a One-Hour Application

Topical ophthalmic antibiotics are common prescribed just prior to eye surgery to lower the risk of infection. Previous studies have suggested that antibiotics containing a preservative (Zymar) kill bacteria much quicker than those without a preservative (Vigamox). The purpose of this research is to compare how quickly to the two commonly prescribed antibiotics eliminate bacteria from the eye...

Brief Summary

Official Title: “Prospective Randomized Comparison of Zymar(Gatifloxacin) and Vigamox (Moxifloxacin) in Killing Conjunctival Bacterial Flora Following a One-Hour”

Condition Keyword(s):

Topical ophthalmic antibiotics are common prescribed just prior to eye surgery to lower the risk of infection. Previous studies have suggested that antibiotics containing a preservative (Zymar) kill bacteria much quicker than those without a preservative (Vigamox).

The purpose of this research is to compare how quickly to the two commonly prescribed antibiotics eliminate bacteria from the eye surface.
