Deciding whether to have surgery is difficult because:
You may not be in pain or notice any vision loss.
Your vision may get worse right after surgery and may be affected for weeks or months. Your eyesight may not be as good as it was before the surgery.
Surgery isn't a complete cure for
glaucoma. But surgery can decrease the chance of losing even more eyesight
later on. And for some people, it can reduce or get rid of the need for eyedrops.
Not everyone who has laser surgery will have lower
IOP after the surgery. For most people, the lower pressure
will last only a few years. Others may have an increase in their eye pressure.
Certain types of open-angle glaucoma respond better to laser surgery than
The effects of some laser treatments aren't long-lasting.
Repeat laser treatments, medicines, or other surgeries may be needed later
As with any other surgery, you and your doctor should
make the decision to operate based on the risks and benefits of having the
surgery. One thing to consider is
which eye should be operated on first. There may be other
questions about glaucoma surgery that you should
discuss with your doctor before making a decision.
Cataracts may occur in people who also have glaucoma. This commonly occurs in older people. Surgery to remove the cataract may be
done at the same time as surgery for glaucoma. If
surgeries for glaucoma and a cataract are done at the
same time, you may notice improved eyesight after surgery.
