If you’re going to have cataract surgery or Glaucoma surgery, you may be given some medical tests first.
1)Electrocardiogram (ECG) to check your heart,
2)complete blood count (CBC) to check for anemia, a low amount of red blood cells.
3) urine examination to rule out urine infection
4)blood sugar levels
5) HIV test
6) sr urea, creatinine as required
These tests may make surgery safer. For example, they may find medical problems that lead to a delay or change in your surgery.
Generally, cataract and other eye surgeries have very low risks of complications or problems, such as heart attacks. There really isn’t anything doctors can do to lower the risk any further. Eye surgeries do not take long, and they use only a local anesthetic to numb the eye, often with a medicine to relax you.
You may need the tests if you have certain kinds of health conditions or illnesses. For example, you may need an ECG if you have heart disease or symptoms such as chest pain or shortness of breath. If you have diabetes, you will probably need a blood test to make sure it is under control.
Based on the test results, your doctor may need to change your surgery or anesthesia. You may need special care during or after the surgery. Or you may need to postpone the surgery until the problem is treated or controlled.
