- Abstract
Purpose: Lidocaine gel was suggested to be highly effective in providing anesthesia for intravitreal injections but adverse effects include a possibility of making sterilization of the conjunctiva difficult. Hence, we wished to determine the effect of using 0.5% proparacaine drops alone over the use of 3.5% lidocaine hydrochloride gel anesthesia during office-based intravitreal injections., Methodology: This was a case-control study in patients who came routinely to the clinic for antivascular endothelial growth factor injections. Eyes were treated with one of two anesthesia modalities. A total of 216 injections in 120 patients were reviewed. One group (N = 107) underwent anesthesia with 0.5% proparacaine drops, and the control group (N = 109) received 3.5% lidocaine gel. The pain perceived after injection was graded using the numerical rating scale, and score was immediately recorded by the "masked" injecting physician., Results: The mean pain score (±SD) for the proparacaine-only group versus gel group was 1.97 (±1.17) versus 1.76 (±0.92), P value = 0.3174. There was no statistical difference between the 2 groups., Conclusion: 3.5% lidocaine gel is not superior to 0.5% proparacaine drops as patients attained good pain control and excellent rates of overall satisfaction with proparacaine drops alone.
