Randomized Controlled Trial Comparative Study Clinical TrialComparison of diclofenac sodium and flurbiprofen for inhibition of surgically induced miosis.
To compare the efficacy of two topical nonsteroidal anti-inflammatory drugs, diclofenac sodium and flurbiprofen, commonly used prior to cataract surgery to inhibit surgically induced miosis. ⋯ Diclofenac sodium and flurbiprofen were equally effective in maintaining intraoperative mydriasis during cataract surgery.

Randomized Controlled Trial Comparative Study Clinical TrialRelative effectiveness of topical ketorolac and topical diclofenac on discomfort after radial keratotomy.
Two prospective, randomized, double-masked studies were conducted evaluating the analgesic effect of topical eyedrops after radial keratotomy (RK). One study of 117 consecutive initial RK procedures compared topical ketorolac (Acular) with topical diclofenac (Voltaren), and another study of 23 consecutive initial RK procedures compared topical ketorolac with a control medication (HypoTears). ⋯ The onset of analgesic effect of these topical nonsteroidal anti-inflammatory drugs is longer than one hour. The analgesic effect of oral acetaminophen #3 significantly augments that of topical diclofenac drops for those experiencing any discomfort by six hours after surgery.

Multicenter StudyEfficacy and complication rate of 16,224 consecutive peribulbar blocks. A prospective multicenter study.
Although usually safe, retrobulbar anesthesia and peribulbar anesthesia have potentially sight- and life-threatening complications. Although it has been suggested that peribulbar anesthesia is as effective and safer than retrobulbar anesthesia, no large study has addressed the true rate of complications. To determine the efficacy and safety of peribulbar anesthesia, this study prospectively examined 16,224 consecutive peribulbar blocks. ⋯ There was one globe perforation (0.006%), two expulsive hemorrhages (0.013%), one grand mal seizure (0.006%), and no cases of cardiac or respiratory depression or deaths. Peribulbar is as effective as retrobulbar anesthesia and appears to lead to fewer sight- and life-threatening complications, even when slightly different peribulbar techniques are used. This is especially true when the anesthetic is administered with a 1 1/4-inch or shorter needle with the eye in the primary position, followed by ten to 15 minutes of ocular compression.

Any needle passing through a rubber stopper can aspirate a core of rubber. This rubber may then be injected into the eye or into the retrobulbar or peribulbar space. Aspirates from a number of syringes were spun down in a centrifuge and examined for microscopic particles. All specimens contained microscopic particles even from half-used bottles of Xylocaine.

A modified version of peribulbar anesthesia is described. An analysis of 230 consecutive ophthalmic procedures including cataract surgery, penetrating keratoplasty, and scleral buckling demonstrates the safety and effectiveness of this modified peribulbar anesthesia technique.
