| Current Primary Outcome Measures |
ocular flora resistance to 4th generation fluoroquinolone [ Time Frame: 1 year ] Outcome will examine the change in amount, type and antibiotic resistance profile of ocular surface flora over the 3 months. Charcoal swab of the conjunctiva will be cultured, organisms grown will be identified and resistance to moxifloxacin will be quantified by minimal inhibitory resistance (MIC).

| Original Primary Outcome Measures |
ocular flora resistance to 4th generation fluoroquinolone [ Time Frame: pre and post intravitreal injection for 3 months ] Outcome will examine the change in amount, type and antibiotic resistance profile of ocular surface flora over the 3 months. Charcoal swab of the conjunctiva will be cultured, organisms grown will be identified and resistance to moxifloxacin will be quantified by minimal inhibitory resistance (MIC).
