f you're going to have cataract surgery or another eye surgery, you may be given some medical tests first. For example, you may have an electrocardiogram (EKG) to check your heart, or a complete blood count (CBC) to check for anemia, a low amount of red blood cells. These tests may make surgery safer.
For example, the doctor may conduct a potential acuity (PAM) test. This test measures how well you would see if you did not have a cataract present in the eye. This is a great test because the surgeon needs to determine whether cataract surgery will indeed improve your vision.
It's estimated that around 80% of patients see colours during their cataract surgery.

The elevation in IOP typically peaks at 3 to 7 hours after cataract extraction, persists for the first 24 hours, and returns to nearly normal levels within 48 hours. Numerous studies have documented this rise in IOP after cataract surgery, and it can be as high as 40 mm Hg in some cases.
