Comparing Efficacy and Safety of Intracameral Injection of Marcaine and Lidocaine on Postoperative Pain and Recovery After Cataract Surgery

Various topical (intracameral) analgesics are used to relieve postoperative pain after cataract surgery.

We decided to compare the effects of intracameral Marcaine and lidocaine on pain intensity after the cataract operation.

In this double-blind, randomized clinical trial, 64 patients who were candidates for cataract surgery were randomly assigned to either anesthesia with lidocaine or bupivacaine (Marcaine) by intracameral injection. Study endpoints included pain score, hemodynamic status, patient satisfaction, and recovery duration.

The Marcaine group experienced a shorter recovery than another group (P = 0.001). The mean pain score at the different time points after the operation was significantly lower in the group receiving Marcaine than those receiving lidocaine (P < 0.001). Our study showed a higher level of patients’ satisfaction with Marcaine as compared to the lidocaine group (P = 0.026). However, postoperative hemodynamic status was similar in both groups.

Compared with lidocaine, intracameral injection of Marcaine results in a shorter postoperative recovery period, reduced pain intensity, and higher satisfaction among patients after cataract surgery.
