Randomized Controlled Trial Comparative Study Clinical Trial
A comparison of patient comfort during cataract surgery with topical anesthesia versus topical anesthesia and intracameral lidocaine.
To determine whether intraocular lidocaine increases patient comfort during cataract surgery while under topical anesthesia. ⋯ Both topical anesthesia alone and topical anesthesia plus intracameral lidocaine provide good operative conditions for the surgeon and comfortable surgical circumstances for the patient. Injection of intraocular lidocaine increases patient cooperation and decreases the degree to which patients are bothered by tissue manipulation, two outcomes that justify its use.

Multicenter Study
Intraoperative clinical practice and risk of early complications after cataract extraction in the United States, Canada, Denmark, and Spain.
To examine variation in intraoperative clinical practice and rates of adverse events after cataract surgery across four different healthcare systems. ⋯ The observed variation in clinical practice might represent a general trend of a slower diffusion of new medical technology in Europe compared with that of North America. Rates of intraoperative and early postoperative events varied significantly across sites.
