The effect of ketorolac tromethamine in reducing postoperative inflammation: double-mask parallel comparison with dexamethasone.

Anterior chamber fluorophotometry was done after the oral administration of fluorescein sodium in patients undergoing extracapsular cataract extraction and posterior chamber intraocular lens insertion before and after surgery. The administration of ketorolac solution 0.5% eye drops before and after surgery decreased the breakdown of the blood-aqueous barrier as much as did dexamethasone sodium phosphate solution 0.1% (dexamethasone solution) eye drops at each postoperative time period as measured by fluorophotometry. Slit-lamp observations of postoperative anterior ocular inflammation were not different between treatment groups. Both ketorolac and dexamethasone solutions were well tolerated by patients. No additional corticosteroids were given to any patients during the study. Therefore, ketorolac solution was as effective as dexamethasone solution in suppressing postoperative inflammation after cataract surgery as measured by fluorophotometry and as observed by slit-lamp examinations. This study confirms prior studies that suggest ketorolac ophthalmic solution 0.5% may be effective and safe as a nonsteroidal antiinflammatory agent for topical use after cataract surgery and intraocular lens implantation and as a substitute for topically applied corticosteroids.
