Title: Effect of Topical Diclofenac and Ketorolac on Patient Discomfort and Corneal Sensitivity
Abstract: To determine if at clinical dosages, the topical nonsteroidal anti-inflammatory drugs diclofenac and ketorolac decrease corneal sensitivity, and if there is a difference in discomfort on instillation.In a double-masked study, 30 patients were randomized to receive two of three topical drops, Endosol, diclofenac sodium, and ketorolac tromethamine. A microaesthesiometer was used to evaluate corneal sensation. Baseline corneal sensitivity was obtained on each patient. Corneal sensory thresholds were remeasured at 7 and 15 minutes following eyedrop application. Patients also completed a questionnaire that graded the burning caused by the medications.No significant decrease in corneal sensory thresholds was found with diclofenac or ketorolac compared with control at baseline (P = .50), 7 minutes (P = .41), or 15 minutes (P = .82). There was significantly more burning with diclofenac and ketorolac compared to control. There was a small but not statistically significant (P = .28) trend of more burning with ketorolac than diclofenac.Neither diclofenac nor ketorolac were found to decrease corneal sensation compared to control. There was no significant difference in burning upon instillation reported by patients.
