Randomized Controlled Trial Comparative Study Clinical TrialEffectiveness of sub-Tenon's versus peribulbar anesthesia in extracapsular cataract surgery.
To compare the effectiveness of sub-Tenon's versus peribulbar anesthesia in extracapsular cataract surgery. ⋯ Sub-Tenon's anesthesia led to less IOP elevation than peribulbar anesthesia and provided similarly good globe immobilization and approximately the same pain levels intraoperatively.

Randomized Controlled Trial Comparative Study Clinical TrialComparison of ketorolac tromethamine, diclofenac sodium, and moist drops for ocular pain after radial keratotomy.
To compare the 2 most popular commercially available topical nonsteroidal anti-inflammatory drugs (NSAIDs) in the treatment of ocular pain following radial keratotomy (RK). ⋯ Both ketorolac tromethamine and diclofenac sodium were more effective in reducing post-RK discomfort than the control (moist artificial tears). Given the large number of tests and the small number that tested as significant, the significant differences (7 of 210 measurements) observed among the 3 treatment groups probably occurred by chance, although the improved foreign-body sensation, functionality, and compliance scores in the ketorolac group during the first 4 hours might be clinically important.

After having a retrobulbar injection for anesthesia before cataract surgery, a patient developed dysarthria. This was the presenting sign for penetration of the optic nerve sheath by the retrobulbar injection, with subsequent brainstem anesthesia. Thereafter, the patient demonstrated cranial nerve dysfunctions with tongue deviation, tachycardia, hypertension, and contralateral sixth and third nerve palsies. I believe this is the first documented case in which dysarthria is the presenting sign for brainstem anesthesia resulting from a retrobulbar injection.

Randomized Controlled Trial Comparative Study Clinical TrialComparison of the efficacy and safety of ketorolac tromethamine 0.5% and prednisolone acetate 1% after cataract surgery.
To compare the anti-inflammatory and analgesic efficacy and safety of ketorolac tromethamine 0.5% ophthalmic solution with those of prednisolone acetate 1% in patients having cataract surgery. ⋯ Ketorolac tromethamine 0.5% ophthalmic solution was as effective and well-tolerated as prednisolone acetate 1% solution in controlling postoperative inflammation and pain after cataract surgery.

Randomized Controlled Trial Comparative Study Clinical TrialProvision of anesthesia with single application of lidocaine 2% gel.
To compare the efficacy of a single application of lidocaine 2% gel with tetracaine 0.5% drops for topical anesthesia in clear corneal cataract surgery. ⋯ A single application of lidocaine 2% gel was a safe and effective alternative to multiple topical anesthetic drops for clear corneal cataract surgery. Lidocaine 2% gel was similar to tetracaine drops in provision of corneal anesthesia and patient comfort, while causing no significant toxicity to the ocular surface.
