YAG capsulotomy
Pronunciation: YAG KAP-soo-lot-oh-mee
Laser procedure to create an opening in the clouded posterior lens capsule following cataract surgery.
Full Definition
YAG laser posterior capsulotomy is a non-invasive outpatient procedure used to treat posterior capsule opacification (PCO), commonly known as secondary cataract, which can develop months to years after cataract surgery. The procedure uses a neodymium:YAG laser to create a small central opening in the thickened posterior capsule, immediately restoring clear vision. The laser treatment is performed through the dilated pupil and typically takes only a few minutes with minimal discomfort. Potential risks include elevated intraocular pressure, retinal detachment, and IOL damage, though serious complications are rare.
Usage
Usage note: YAG refers to the type of laser used (neodymium:yttrium-aluminum-garnet); distinguish from other YAG procedures.
