Comparative StudyCorrelation of infrared pupillometers and CCD-camera imaging from aberrometry and videokeratography for determining scotopic pupil size.
To compare 2 infrared pupillometers with a videokeratographer and 2 aberrometers for the determination of scotopic pupil size. ⋯ The Zywave wavefront sensor with the fixating target turned off using the study settings and light conditions provided measurements of scotopic pupil diameter that were closest to the reference values (Procyon). With the other devices (Colvard pupillometer, Zywave aberrometer with the fixating target switched on, Wasca aberrometer, and Orbscan topographer), the difference was statistically significant.

Randomized Controlled Trial Multicenter Study Clinical TrialSafety and efficacy of ketorolac tromethamine 0.4% ophthalmic solution in post-photorefractive keratectomy patients.
To evaluate the safety and analgesic efficacy of ketorolac tromethamine 0.4% ophthalmic solution in postoperative photorefractive keratectomy (PRK) patients. ⋯ Ketorolac 0.4% ophthalmic solution is safe and effective in reducing ocular pain when used 4 times daily for up to 4 days post PRK.

Randomized Controlled Trial Comparative Study Clinical TrialEffect of topical brinzolamide 1% and brimonidine 0.2% on intraocular pressure after phacoemulsification.
To compare the effectiveness of brinzolamide 1% (Azopt) and brimonidine 0.2% (Alphagan) with a placebo in preventing an early increase in intraocular pressure (IOP) after phacoemulsification. ⋯ Prophylactic use of 1 drop of brinzolamide or brimonidine was not more effective than a placebo in controlling early postoperative IOP elevations after clear corneal phacoemulsification.

Randomized Controlled Trial Comparative Study Clinical TrialComparative clinical trial of topical anesthetic agents in cataract surgery: lidocaine 2% gel, bupivacaine 0.5% drops, and benoxinate 0.4% drops.
To assess the efficacy of lidocaine gel, bupivacaine drops, and benoxinate drops as topical anesthetic agents in cataract surgery. ⋯ Lidocaine gel was a better topical anesthetic agent than bupivacaine and benoxinate drops. Bupivacaine drops were effective in providing deep topical anesthesia.
