Randomized Controlled Trial Comparative Study Clinical TrialTopical tetracaine versus topical tetracaine plus intracameral lidocaine for cataract surgery.
To compare topical tetracaine 0.5% alone and with intracameral lidocaine 1% as a local anesthetic agent in phacoemulsification with intraocular lens (IOL) implantation. ⋯ Topical tetracaine 0.5% with intracameral lidocaine was safe and effective in patients having phacoemulsification with IOL implantation. The advantage of using intracameral lidocaine 1% over a placebo was a significant decrease in the patients' subjective experience of pain and in the surgeon's satisfaction with the anesthesia used. None of the other parameters measured in this study differed significantly between the 2 groups.

Randomized Controlled Trial Comparative Study Clinical TrialPain in scleral pocket incision cataract surgery using topical and peribulbar anesthesia.
To evaluate the pain produced during different phases of phacoemulsification cataract surgery using a scleral pocket incision under topical versus peribulbar anesthesia. ⋯ Considering the entire procedure, total pain using topical anesthesia was acceptable and equal to that using peribulbar anesthesia for phacoemulsification with a scleral pocket incision. Pain during phacoemulsification was greater under topical anesthesia but not significantly different from the pain during the peribulbar injection.
