Full Definition
YAG capsulotomy is a non-invasive outpatient laser procedure that treats posterior capsule opacification (PCO), a common complication following cataract surgery. The procedure uses a neodymium:yttrium-aluminum-garnet (Nd:YAG) laser to create a circular opening in the clouded posterior lens capsule, restoring clear vision. The treatment is quick, painless, and highly effective, though it carries small risks of retinal detachment, elevated intraocular pressure, and IOL damage.
Usage
Usage note: YAG is always capitalized; avoid redundant phrasing like 'YAG laser capsulotomy procedure.'
