OBJECTIVE To determine whether lidocaine 2% jelly is an effective topical anesthetic agent for cataract surgery. METHODS Private practice and surgicenter. METHODS One hundred eighty cataract surgery patients were randomly assigned to 1 of 4 groups of 45 patients each: Group 1-topical eyedrop anesthesia; Group 2-intracameral lidocaine; Group 3-lidocaine 2% jelly applied once, on arrival at the surgicenter; and Group 4-lidocaine 2% jelly applied on arrival and about 5 minutes prior to surgery. Each patient was asked about pain or pressure sensation during the operation and afterward. RESULTS Single instillation of lidocaine 2% jelly was associated with pain scores comparable to those with topical eyedrop anesthesia. When the jelly was readministered shortly before surgery, the pain scores were comparable to those with intracameral anesthesia. CONCLUSIONS Lidocaine 2% jelly was an effective agent in cataract surgery.

UI MeSH Term Description Entries
D008012 Lidocaine A local anesthetic and cardiac depressant used as an antiarrhythmia agent. Its actions are more intense and its effects more prolonged than those of PROCAINE but its duration of action is shorter than that of BUPIVACAINE or PRILOCAINE.

D000779 Anesthetics, Local Drugs that block nerve conduction when applied locally to nerve tissue in appropriate concentrations. They act on any part of the nervous system and on every type of nerve fiber. In contact with a nerve trunk, these anesthetics can cause both sensory and motor paralysis in the innervated area. Their action is completely reversible. (From Gilman AG, et. al., Goodman and Gilman's The Pharmacological Basis of Therapeutics, 8th ed) Nearly all local anesthetics act by reducing the tendency of voltage-dependent sodium channels to activate.
