title: Prophylactic postoperative ketorolac improves outcomes in diabetic patients assigned for cataract surgery.
abstract: OBJECTIVE
  To evaluate the prophylactic role of topical non-steroidal anti-inflammatory drugs in reducing the incidence of central macular edema (CME) in diabetic eyes post-cataract surgery.
  
  
  METHODS
  This study included 86 eyes (70 patients) with high risk characteristics for the development of CME after cataract surgery. All patients underwent phacoemulsification and intraocular lens implantation. Patients were divided into two equal groups (n = 43 [eyes]): a control group given topical dexamethasone 0.1%, four times/day for 12 weeks postoperatively and a study group given topical ketorolac tromethamine 0.4% twice daily in addition to topical dexamethasone 0.1% four times daily for 12 weeks. Patients were examined at 3, 6, and 12 weeks postoperatively for evaluation of CME development. The main study outcome was the change in the retinal fovea thickness measured with ocular coherence topography.
  
  
  RESULTS
  Ten eyes developed CME (11.6%); eight eyes in the control group and only two eyes in the study group. Mean retinal fovea thickness was significantly higher in the control group compared to the study group. Moreover, eyes of the control group developed CME significantly earlier than those of the study group.
  
  
  CONCLUSIONS
  Prophylactic postoperative ketorolac 0.4% may have a role in reducing the frequency and severity of CME in diabetic eyes post-cataract surgery.
