YAG laser capsulotomy, often referred to as YAG surgery, is a procedure performed to restore clear vision after cataract surgery. It addresses a common issue where vision becomes blurry again months or years after the initial cataract surgery due to clouding of the posterior capsule, a membrane in the eye.
Why is YAG Surgery Needed?
After cataract surgery, the natural lens of the eye is replaced with an artificial lens. The artificial lens is placed within the existing lens capsule. Over time, this capsule can become cloudy, a condition known as posterior capsule opacification (PCO). This clouding obstructs light from properly reaching the retina, resulting in blurred or distorted vision. YAG laser capsulotomy is then needed to create an opening in this cloudy capsule.
How Does YAG Surgery Work?
YAG laser capsulotomy is a non-invasive procedure performed using a YAG (yttrium aluminum garnet) laser. Here's a simplified breakdown:
-
Preparation: The eye is dilated with eye drops to widen the pupil.
-
Laser Application: A YAG laser is used to create a small opening in the clouded posterior capsule. This opening allows light to pass through clearly, restoring vision.
-
Painless Procedure: The procedure is typically painless and quick, often taking only a few minutes.
-
Quick Recovery: Recovery is usually rapid, with most people noticing improved vision within a day or two.
Key Benefits of YAG Surgery
- Restores Clear Vision: The primary benefit is the restoration of clear vision that was lost due to posterior capsule opacification.
- Non-Invasive: The procedure is non-invasive, meaning no incisions are required.
- Quick and Painless: YAG laser capsulotomy is generally quick and painless.
- Outpatient Procedure: It is performed as an outpatient procedure, allowing patients to return home shortly after.
