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.

Arms Assigned Interventions
Experimental: 1 Topical Anesthetic Drug: betadine
betadine 5%
Other Name: povidone-iodine
Drug: topical tetracaine
topical anesthetic
Other Names:
  • Ak-taine
  • Ak-T-Caine
  • Alcaine
  • Ocu-Caine
  • Ophthaine
Active Comparator: 2 Anesthetic Drug: betadine
betadine 5%
Other Name: povidone-iodine
Drug: lidocaine
lidocaine 2% jelly
Other Name: Xylocaine Jelly

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%.
