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.

To identify the most popular forms of complementary and alternative medicine (CAM) for glaucoma on the Internet and to assess the quality of the most popular Web sites addressing CAM for glaucoma. ⋯ Medical information conveyed over the Internet is of variable quality and is not subject to regulation. Many sources of information contain advice on therapies that have no evidence base and may put patients at risk. It is important that researchers and health care providers be aware of the content and quality of this information so as to offer advice to patients about the evidence and potential risks of CAM therapies. This can only be achieved by increasing awareness among ophthalmologists of the range of products and quality of information available for CAM therapies for glaucoma.
