title: Efficacy of preoperative versus postoperative ketorolac tromethamine 0.5% in reducing inflammation after cataract surgery.
abstract: OBJECTIVE
  To compare the efficacy of 30 minute preoperative versus 1 day postoperative administration of ketorolac tromethamine 0.5% ophthalmic solution (Acular) in reducing anterior chamber inflammation after cataract surgery.
  
  
  METHODS
  The Hermann Eye Center, The University of Texas Health Science Center-Houston, Texas, USA.
  
  
  METHODS
  Fifty eyes of 48 consecutive patients scheduled for phacoemulsification with intraocular lens implantation were included. Before surgery, patients were randomly assigned to start the study drug 30 minutes preoperatively or 1 day postoperatively. No other antiinflammatory agents were used intraoperatively or postoperatively. Main outcome measures were flare and cell counts.
  
  
  RESULTS
  Preoperative and postoperative flare and cell counts did not differ significantly between the 2 treatment groups at any time. Both groups showed significant increases in flare (P =.0001) and cells (P =.0001) 1 day postoperatively. Flare and cells returned to baseline levels by day 28 in both groups. There was no significant difference at any time between the 2 groups in the change from the preoperative level of inflammation.
  
  
  CONCLUSIONS
  There was no difference between administering ketorolac 30 minutes preoperatively versus 1 day postoperatively in reducing inflammation.
