The Nd:YAG laser is a solid-state laser that emits in the infrared frequency and that is frequently used for ophthalmology treatment.
It is an outpatient procedure in which the patient is administered anesthetic drops in the eye.
It is performed in the doctor’s office with an equipment similar to the slit lamp (used by the ophthalmologist in each patient’s visit.) The patient is asked to sit down and to place their chins and foreheads on the microscope, which is connected, through optical fiber, with the source that emits the “YAG LASER” laser beam. The patient is told to focus the other eye on a light, and to follow the instructions given by the ophthalmologist. Finally, the patient is administered some drops in the treated eye in order to prevent a potential intraocular pressure increase. The Yag Laser emits two convergent beams. When these beams cross, they destroy the molecular structure of matter without increasing the temperature. In this way, the laser cuts tissue.
YAG LASER Posterior capsulotomy involves opening the opaque posterior capsule, which is behind the intraocular lens implanted in the cataract surgery, through laser shots.
Through this process, it is possible to get back the visual intensity of the eye which was lost before the opacification of the posterior capsule.
When treating glaucoma, different procedures are possible. The choice depends on the type of glaucoma and its acuteness.
Yag Laser Iridotomy involves a hole in the iris, creating a new drainage path for the aqueous humor, controlling intraocular pressure and preventing acute glaucoma. It is used in the treatment of narrow angles and narrow angle glaucoma.
