A) YAG Laser Capsulotomy –
One of the most common cataract surgery complications is a posterior capsule opacity (PCO). When a cataract is removed, the surgeon makes every attempt to maintain the integrity of the lens capsule. In about 20% of the patients, the posterior portion of the lens capsule becomes hazy sometime during cataract surgery recovery or even months later causing PCO. YAG laser capsulotomy is a non invasive laser procedure used to treat PCO. The laser shot removes the hazy posterior capsule from the line of sight without making an incision or “touching” the eye. This allows light to pass through the membrane to the retina at the back of the eye. This procedure is entirely painless and only takes a few minutes. It does not cause discomfort either.
B) YAG Laser Iridotomy –
This procedure is done to treat close angle glaucoma after the pressure in the affected eye has been reduced with medicines or when medicines fail. It prevents closed angle glaucoma in people who have a narrow drainage angles and people who have had closed angle glaucoma in the other eye. It uses a very focused beam of light to create a hole on the outer edge or rim of the iris. This opening allows fluid to flow between the anterior chamber and the posterior chamber of the eye. This opening may decrease pressure in the eye and prevents sudden build up of pressure within the eye. The eye is usually pretreated about half an hour before the procedure with drops that make the pupil small. Just before the procedure anaesthetic drops are placed to numb the surface of the eye. A lens is then placed on the eye to perform the laser. It takes 5-10 mins.
C) Argon Laser treatment -
Argon laser treatment is used to treat a variety of eye conditions such as diabetic retinopathy, retinal breaks, glaucoma and macular degeneration. It is commonly used to minimize leakage of fluid from blood vessels in the retina or to prevent development of abnormal blood vessels in the eye.
