Outcomes
Primary Outcome Measures
Change in Ln(Bacterial Colony Count) From Pre-antibiotic Administration to Post Study Medication Swabs
Within 3 hours from time of culture acquisition, the samples will be vortexed for 30 seconds and 100µl aliquots will be plated onto 5% sheep blood and chocolate agar plates. These plates will be incubated with 5% carbon dioxide at 35˚ C for 72 hours. After 72 hours all plates will be read for colony count and identification of all isolates will be performed using routine microbiological methods. The natural log of bacterial bacterial colony count will be used for the outcome measure.

5. Study Description
Brief Summary
The purpose of this study is to determine if there is a difference on the penetration of betadine 5% when using lidocaine 2% jelly versus topical tetracaine 0.5% in topical cataract surgery. This will be assessed comparing bacterial colony count and species by taking swabs from the eye surface before and after the topical anesthesia has been administered.
Detailed Description
The purpose of this research study is to show that using Lidocaine2% jelly before surgery as an anesthetic (keep you from feeling touch or pain) for cataract surgery does not block the antiseptic (cleans and kills germs) effect of Betadine5%.
