The Value of Routine Preoperative Medical Testing Before Cataract Surgery
N Engl J Med 342: 168-175, 2000
The rates of perioperative morbidity and mortality after cataract surgery are low, despite the fact that patients are elderly and have serious coexisting illnesses. These patients commonly undergo routine medical testing before cataract surgery. A prospective randomized clinical trial was performed to determine whether routine medical testing before cataract surgery reduces the rate of complications in the perioperative period.
It was concluded that routine medical testing before cataract surgery does not improve the safety of the surgical procedure. It is possible to save the high costs of routine medical testing without any negative effects on patients health or clinical outcome. It is also reasonable to apply these observations to other patients undergoing other surgeries with low surgical risks, under local anesthesia and IV sedation.
