Have you had cataract surgery and are experiencing hazy vision? If so, you may be experiencing posterior capsule opacity - also known as ‘secondary cataracts’.
In about 20-40% of cataract surgery patients, the thin membrane behind the lens thickens. The thickening causes cloudiness of the lens membrane and can happen anywhere between a few months to years after your surgery. When this occurs, your eye doctor may recommend a YAG capsulotomy laser to improve your vision.
What is a YAG Capsulotomy?
A YAG capsulotomy is a special laser treatment used to improve your vision after cataract surgery. It is a simple, commonly performed procedure which is very safe. In a YAG capsulotomy the doctor uses a specialised YAG laser to make a small hole in the posterior capsule (the membrane behind the lens of your eye) removing the posterior capsule opacity or ‘haziness’. This creates a small hole in the center of the capsule, which lets light through.
The procedure takes only a few minutes and is entirely painless. There is also no discomfort after the procedure. Following a YAG capsulotomy, you can resume normal activities straight away.
What are the Benefits of a Yag Capsulotomy?
Because the YAG capsulotomy removes the central zone of the cloudy posterior capsule behind the intraocular lens, the condition cannot return. So only one laser treatment is required to permanently eliminate vision loss caused by posterior capsule opacification after cataract surgery.
The procedure is also extremely fast. It can be performed in the office, so there is no need to go into surgery, and as mentioned previously, it’s completely painless as well. Although a YAG capsulotomy poses slight additional risk, overall the procedure is extremely safe.
