Abstract
Purpose
To evaluate and compare the pain experience and discomfort during cataract surgery and over the 24 hours after surgery in patients undergoing either topical anesthesia alone or topical anesthesia plus intracameral anesthesia, provided by using a standard topical anesthesia regimen and a 0.2-mL dose of Mydrane®.
Methods
Prospective study involving 100 patients who underwent cataract surgery receiving either topical anesthesia alone (group 1, n = 50) or topical anesthesia plus intracameral anesthesia (group 2, n = 50) between January 2021 and March 2022. The pain experienced by patients during and after surgery was assessed using a pain scale and a questionnaire. One hour after surgery, patients were asked to rate the intensity of discomfort they experienced throughout the procedure by pointing to a 0–100 Visual Analogue Scale (VAS).
Results
According to VAS measurements, patients who underwent surgery under topical anesthesia reported more significant pain than those who underwent surgery under topical anesthesia plus intracameral anesthesia during and over the 24 hours after surgery. (p = 0.02 and p = 0.01, respectively). Patients undergoing topical anesthesia had 2.34-fold greater odds of having pain during surgery [95% Confidence Interval (CI): 1.58–5.25, p = 0.03].
Conclusions
Topical anesthesia plus intracameral anesthesia lower intraoperative and postoperative pain levels, improving patient cooperation and representing a useful analgesic delivery method in cataract surgery.
