Surgery reduces the pressure in the eyes by opening blocked
drainage angles or creating a new opening that fluid can
flow through to leave the eye. In some cases surgery may be done to relieve pain caused by

Staring at a computer monitor for hours on end has become a part of the modern workday. And inevitably, all of that staring can put a real strain on your eyes.
The name for eye problems caused by computer use is computer vision syndrome (CVS). CVS is not one specific eye problem. Instead, the term encompasses a whole range of eyestrain and pain experienced by computer users.
Research shows computer eye problems are common. Somewhere between 50% and 90% of people who work at a computer screen have...
Doctors can use
either a surgical cutting tool or a very focused beam of light, called a laser,
to do surgery for glaucoma.
Laser surgery is usually the first type of surgery tried. If laser surgery doesn't help, your doctor may try

unusual for some people to have both open- and closed-angle glaucoma. They may need more than one kind of procedure.
Surgery choices for adults
There are three basic types of surgery for glaucoma in
Surgery to increase drainage of fluid from the eye
This type of surgery involves making a trapdoor that allows fluid to
drain from the eye.
involves an incision to remove a piece of tissue to allow fluid to drain from the
Tube-shunt surgery (seton glaucoma surgery) involves an incision to place a
tube in the eye to allow fluid to drain.
Laser sclerostomy removes a piece of the white part of the eye to allow fluid
to drain. This type of surgery is rarely done.
Surgery to prevent closure of the drainage angle
These procedures involve making a new opening in the
colored part of the eye (iris) that allows fluid to flow through the eye. They
are used to treat sudden (acute) and long-term closed-angle glaucoma. The procedures also will prevent
closed-angle glaucoma in people who have narrow drainage angles.
glaucoma, there are two slightly different procedures that both attempt to open
the drainage angle directly. They are equally successful in children, but they
are not used for adults. If these procedures fail in a child, then
trabeculectomy or tube-shunt surgery may be tried.
