To evaluate the effect of oral gabapentin premedication on hyperalgesia in elderly patients undergoing staged bilateral cataract operations under monitored anesthesia care
It has been reported that patients with bilateral cataract complained more pain and discomfort during the second consecutive eye surgery compared to the first eye surgery. Gabapentin is an anticonvulsant drug, which has been extended the use to perioperative analgesia, and anxiolysis. Therefore, the investigators conducted this randomized, controlled study to evaluate the effects of gabapentin premedication on patients' subjective sensations, including intraoperative anxiety, perceptions of pain, and light sensitivity, in the second cataract operations.
