Arm Intervention/treatment
Experimental: Nevanac
One drop, three times daily, in the assigned eye for the first three postoperative days
Drug: nepafenac 0.1%
Nepafenac 0.1% randomly assigned to one eye, with ketorolac 0.4% in the fellow eye for contralateral post-surgical use.
Placebo Comparator: Acular LS
One drop, three times daily, in the assigned eye for the first three postoperative days
Other: ketorolac 0.4%
Keterolac 0.4% randomly assigned to one eye, with nepafenac 0.1% in the fellow eye for contralateral post-surgical use.



Primary Outcome Measures :
  1. Subjective pain [ Time Frame: Day 5 ]

Secondary Outcome Measures :
  1. Rate of epithelial healing [ Time Frame: Time to event ]
