    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.

     

    A
    total of 19,248 
    elective cataract surgeries [ 18,819
    patients], from 9 centres, were randomly assigned to
    be preceded or not preceded by a battery of medical
    tests [electrocardiography, complete blood count,
    serum electrolytes, urea nitrogen, creatinine, and
    glucose]., in addition to a history and physical
    examination.

     

    Patients
    were followed up for adverse events during operation
    and during seven days after surgery. 
    In the no-tests group, there were 9408
    patients undergoing 9624 surgeries; and in the other
    group there were 9411 patients with 9624 surgeries.
    The over-all rate of perioprative
    complications was the same for both groups [ 31.3
    events per 1000 surgeries]. The no-testing and the
    testing groups had similar rates of intraoperative
    events [19.2 vs 19.7] and postoperative events [12.6
    vs 12.1] per 1000 surgeries.

      

    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.
