A "laser", or Light Amplification by Stimulated Emission of Radiation, is a concentrated beam of light created when an electrical current passes through a special material.
Used in eye surgery since the 1970's, laser surgery offers an unparalleled degree of precision and predictability. Lasers are now used for a variety of eye diseases.
Sometimes, after cataract surgery, a haze can form on the posterior capsule, diminishing vision.
A laser can be used to quickly and safely create a small opening in the cloudy capsule.
Light is then able to pass through the lens without obstruction, restoring clear vision.
Often effective in treating open-angle glaucoma.
Stimulates the trabecular mesh-work drainage channel to function better.
Does not always replace need for drops, but can help lower eye pressure.
Can also be used as a first line of treatment for patients who are unwilling or unable to use glaucoma eye drops.
The procedure can be repeated in future if necessary.
An anatomic narrow angle is caused by the iris being located too close to the drainage system of the eye.
Patients are at risk for developing acute angle closure glaucoma.
A laser can be used to create a small opening in the iris to prevent a painful acute angle closure attack.
