YAG Laser is used to make a posterior capsule opening, restoring the transparency of the optical media of the eye and improving visual acuity.
The procedure is quick and is done with topical anesthesia, allowing patients to return to their normal activities on the same day. These opacifications are called secondary cataracts, and are relatively common after cataract surgery.
Like all medical procedures, YAG laser also has potential complications, though these are quite rare. These include: transient ocular hypertension, intraocular lens displacement, cystoid macular edema, and retinal detachment.
YAG Laser is also used to perform basal iridectomies and to treat closed-angle glaucomas. This procedure can be used to reestablish the flow of aqueous humor from the ciliary body to the drainage channels in the sclerocorneal angle of the anterior chamber of the eye, or it can be used prophylactically, in eyes with narrow anterior chambers, where there is imminent risk of acute glaucoma.
