Eyedrops may cause a burning or stinging sensation at first, because of the preservative used and not the medicine itself. Some medicines may cause headaches or have other side effects as well. Ask your doctor to show you how to put drops into your eye, and be sure to tell him or her about other medicines you may be taking. This is very important. Because glaucoma often has no symptoms in early stages, you may forget or be tempted to stop taking them.
Laser surgery helps fluid drain out of the eye, for people with open-angle glaucoma.
Although it may be done at any time, the procedure is often done after trying medicines. Laser surgery may be performed in your doctor s office or in an eye clinic. Before the surgery, eye drops will be applied to numb the eye. The intense heat of the laser beam causes some areas of the meshwork to shrink, resulting in stretching of adjacent areas, allowing fluid to drain more easily. Once you have had laser surgery over the entire meshwork, further laser treatment may not help.
