Whether to have glaucoma surgery is a joint decision between you and
your doctor. Talk with your doctor about the risks and benefits of surgery for
you. The following are some questions that you may have about surgery for
glaucoma.
When should I have surgery for glaucoma?
The answer to this question depends on a number of factors,
including whether you have been using medications to treat your glaucoma. Other
factors to consider in making the decision will include whether the pressure in
your eyes has remained high and your vision has gotten worse despite treatment
with medication. Discuss all the options for treating your glaucoma with your
doctor. Get a second opinion if you can.
Where should I go for surgery?
Where you should go for surgery depends on what type of surgery you
need. Some procedures, such as laser trabeculoplasty, can be done in the
doctor's office or without being admitted to the hospital. If you need
conventional surgery, you will need the procedure done in a hospital or walk-in
(ambulatory) surgical center.
What type of surgery should I have?
It is not unusual for some people to have both open- and
closed-angle glaucoma and, therefore, they may require more than one kind of
procedure.
Surgeries for glaucoma can be used to increase the drainage of
fluid from the eye, prevent closure of the drainage angle, or decrease the
amount of fluid produced by the eye. When treatment with medication fails to
lower the pressure in the eyes, trabeculectomy surgery may be offered. See the
Surgery section of this topic.
What kinds of anesthetic are used?
Most laser treatments for glaucoma need anesthetic that is applied
to the eye (topical local anesthetic). For some surgeries, the anesthetic may
instead be injected behind or around the eyeball (retrobulbar or peribulbar
anesthesia). In many eye procedures done today, peribulbar anesthesia is used
more often than retrobulbar anesthesia. General anesthetic, which puts you to
sleep, is not often needed for eye surgery.
Injected anesthetics and general anesthetic can both have dangerous
side effects, although these side effects are rare. To prevent dangerous side
effects from anesthetics, topical local anesthetic is used whenever
possible.
What are the risks of surgery?
The risks vary for each type of surgery or laser treatment. See the
Surgery Choices section of this topic.
Will I have pain after surgery?
After most procedures for glaucoma, there is only mild discomfort.
Severe pain after surgery for glaucoma may be a sign of complications.
Will I be able to stop using eyedrops for glaucoma after surgery?
Many people will need to continue using medication for glaucoma
after successful surgery. However, you may be able to cut down on the number of
drops or amount of medications you use for glaucoma after surgery.
How long is the surgery good for?
Some types of surgery, such as iridectomy, last for life. However,
if complications develop or glaucoma worsens, additional surgery or treatment
may be needed.
