Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialEfficacy and safety of nonpreserved ketorolac ophthalmic solution in postoperative ocular pain following radial keratotomy.
To investigate the efficacy and safety of nonpreserved ketorolac tromethamine 0.5% ophthalmic solution in relieving pain following radial keratotomy (RK). ⋯ Nonpreserved ketorolac tromethamine 0.5% ophthalmic solution was significantly more effective than, and as safe as, the vehicle in alleviating the postoperative pain associated with RK. This resulted in significant improvements in patient quality of life and less need for oral analgesics, suggesting that topical ketorolac is an appropriate treatment option for ocular pain following RK.

Ultrasonic localization of anesthetic fluid in sub-Tenon's, peribulbar, and retrobulbar techniques.
To determine the distribution of anesthetic fluid during 3 regional anesthetic techniques routinely used for phacoemulsification. ⋯ B-scan ultrasonography was a suitable method of identifying the needle position and the distribution of anesthetic fluid in regional ocular anesthesia. The sub-Tenon's technique appears to be the safest method of introducing anesthetic fluid into the retrobulbar space without the potential complications of sharp-needle techniques.
