A YAG laser is a type of laser that uses a synthetic garnet called yttrium aluminum garnet (YAG) to treat a variety of conditions, including:
- Posterior capsule opacification (PCO): Also known as secondary cataracts, PCO occurs when vision becomes cloudy again after cataract surgery. A YAG laser capsulotomy is a quick procedure that uses the laser to create a small opening in the eye’s posterior lens capsule, allowing light to pass through and improving vision.
- Automotive: YAG chips are used in laser igniters to ignite fuel in an engine instead of a spark plug.
- Cancer treatment: YAG lasers are used in cancer treatment.
- Hair removal: YAG lasers are used in hair removal.
- Cosmetic surgery: YAG lasers are used in cosmetic surgery.
- Manufacturing: YAG lasers are used in manufacturing.
YAG lasers are safe and have been used in ophthalmology for decades. The main benefit of YAG lasers is that their light energy passes through the cornea without cutting it, which eliminates the risk of infection.
