Meta Analysis Comparative Study
Supplementary intracameral lidocaine for phacoemulsification under topical anesthesia. A meta-analysis of randomized controlled trials.
We consider a meta-analysis of randomized controlled trials (RCTs) comparing topical anesthesia alone with topical and intracameral anesthesia for phacoemulsification. ⋯ Intraoperative pain during cataract surgery under topical anaesthetic is reduced by intracameral lidocaine. Possible adverse effects of intracameral lidocaine cannot be excluded due to significant heterogeneity in outcome measures between different RCTs. Although a statistically significant reduction in intraoperative pain has been demonstrated, it is not yet possible to recommend this additional intervention without reservations.
