The medical profile of cataract patients.

The purpose of this paper is to highlight the high incidence of significant medical problems in an unselected group of patients undergoing cataract surgery and if possible to decide what medical investigations should be carried out prior to operation. 62.5 per cent of our patients had a significant medical problem and 54.5 per cent were receiving medical treatment. Over 50 per cent had abnormal ECGs and chest X-rays. Confusion was the main complicating factor post-operatively and a course of management for these patients is described. Haemoglobin, urea and potassium, a urinalysis, a fasting blood glucose, chest X-ray and an ECG are suggested to delineate the medical status of these patients and to reduce the risks of general anaesthesia in this group.
