Randomized Controlled Trial Comparative Study
Comparison of topical anesthetics for intravitreal injections : a randomized clinical trial.
To determine whether there is a difference in anesthetic effect between topical proparacaine drops, 4% lidocaine solution, or 3.5% lidocaine gel, and whether this has an impact on the overall injection experience. ⋯ The use of topical proparacaine drops provides very effective and cost-effective anesthesia during office-based intravitreal injections.
