Sumario: | (1) Background: To determine the analgesic effect of pretreatment topical bromfenac instillation in patients undergoing intravitreal anti-VEGF treatment. (2) Methods: A prospective, non-randomized pilot study was conducted in patients scheduled to receive repeated intravitreal anti-VEGF injections at a single tertiary hospital. Before the planned second injection, the patients received topical bromfenac eye drops twice a day for 3 days. At 1, 6, and 24 h after the first and second injections, the post-injection pain scores were determined using the numerical rating scale (NRS) telephonically. (3) Results: A total of 28 patients were enrolled in this study. After the first intravitreal injection, the NRS pain scores were 4.04 ± 1.90 at 1 h, 1.57 ± 1.75 at 6 h, and 0.93 ± 1.27 at 24 h. The pain scores after the second intravitreal injection significantly decreased at each measurement time point (p = 0.002, 0.055, and 0.004, respectively) compared to the first injection. (4) Conclusions: The use of topical bromfenac eye drops before intravitreal injection can lead to a significant improvement in injection-related pain scores, which is the basis for a future large-scale randomized comparative study. |
