Postoperative morbidity following cataract surgery. A comparison of local and general anaesthesia.

Two hundred and thirty-one patients were questioned the day following their cataract surgery to ascertain the incidence of postoperative morbidity. One hundred and nineteen patients received local anaesthesia (LA) and 112 received general anaesthesia (GA). There was a significant difference in the incidence of nausea (21% in GA group, 3% in LA group, p < 0.01), sore throat (41% GA group, 3% LA group, p < 0.01), and bruising of the eye (15% GA group, 39% LA group, p < 0.01). There was no significant difference in the incidence of vomiting, headache, double vision, the severity of postoperative pain, or the need for analgesia. The time before the patients drank and ate postoperatively was significantly shorter in the local anaesthetic group (1.3 h and 1.8 h LA group, 4.1 h and 6.7 h GA group respectively, p < 0.01).
