What to Expect After Cataract Surgery
The probable cataract surgery result depends greatly
upon the preoperative health of your eyes and your
body.
The
presence of co-pathology - other ocular or health problems
in addition to cataracts - can significantly reduce the
probability of the desired outcome. There is
nearly a 21% difference in 20/20 outcomes between no
pathology and co-pathology.
The table below is a general guide,
however every patient is unique and may have higher or lower
probabilities of the reported outcomes. Rely most on the
opinion of a competent doctor after a comprehensive
examination.
The "Big E" Snellen eye test is based
upon the clarity a normally sighted person sees an object at
20 feet (6 meters) away. Snellen 20/20 means that the
patient sees an object 20 feet away with the clarity a
normally sighted person sees that same object 20 feet away.
20/40 means that the patient sees an object 20 feet away
with the clarity a normally sighted person would see that
same object at 40 feet away. 20/200 would be the clarity of
an object 20 feet away that a normally sighted person would
see the same object at 200 feet away.
