The success rate of cataract extraction is very
high, with a good prognosis. A visual acuity of 20/40 or better may
be achieved. If an extracapsular cataract extraction was performed,
a secondary cataract may develop in the remaining back portion of
the capsule. This can occur one to two years after surgery. YAG
capsulotomy is most often used for this type of cataract. YAG stands
for yttrium aluminum garnet, the name of the laser used for this
procedure. This is a painless outpatient procedure and requires no
incision. The laser beam makes a small opening in the remaining back
part of the capsule, allowing light through.
In a very small percentage (3-5%) of surgical
cataract extractions, complications occur. Infections, swelling of
the cornea (edema), bleeding, retinal detachment, and the onset of
glaucoma have been reported. Some problems may occur one to two days,
or even several weeks, after surgery. Any haziness, redness,
decrease in vision, nausea, or pain should be reported to the
surgeon immediately. |
