Kingston Eye Institute also has an assortment of laser treatments available to treat certain eye diseases. Some of the laser treatments performed includes:
- YAG Laser: It is not uncommon after cataract surgery for the clear posterior capsule to become cloudy months to years after the surgery. It is more likely to develop in young patients and following the removal of certain type of cataracts. Like a healing response, the tendency for the capsule to later cloud varies with the individual. If your posterior capsule becomes cloudy it will cause a progressive reduction in vision and can mimic a lot of the symptoms you had initially with your cataract (blurred vision, halos, etc). When the posterior capsule becomes so cloudy that it is affecting your vision a YAG Laser treatment is usually recommended. In the past, the membrane had to be opened with a knife and there were significant risks since the eye was opened. However, with the advent of the YAG Laser treatment the risks have been significantly reduced.
- Argon Laser: used to prevent leakage of fluid from blood vessels at the back of the eye (the retina) or to destroy part of the retina that is encouraging the development of abnormal blood vessels in the eye. These problems may be associated with diabetes or may be caused by other conditions affecting the blood vessels on the retina. Occasionally, argon laser is used to lower the pressure in the eye in glaucoma.
- Selective Laser Trabeculoplasty: Laser trabeculoplasty uses a focused beam of light to treat the drainage angle of the eye. This procedure makes it easier for fluid to flow out of the front part of the eye, decreasing pressure in the eye. It may be helpful in treating people with open-angle glaucoma that continues to get worse in spite of medication treatment. It may also be helpful in treating older adults with open-angle glaucoma who are not able to use medicines to treat the condition.
