Cloudy Vision After Cataract Surgery (YAG Capsulotomy): How It Works, Explained Simply

Video Transcript

Some people notice their vision turning hazy again months or years after cataract surgery. This is common, and it is not the cataract coming back. During cataract surgery, the lens implant is placed inside the thin, clear capsule that once held the natural lens. Over time, cells can grow across the back of that capsule, making it cloudy. This is called posterior capsule opacification. Because light now passes through a cloudy layer, vision can look blurry or washed out, and glare may return. The usual treatment is a quick laser procedure known as a YAG capsulotomy. The laser makes a small opening in the center of the cloudy capsule, creating a clear path for light. It is done in the office, takes only a few minutes, and there is no cut and no stitches. Vision often clears within a day or so, and because the capsule does not grow back, this is usually a one-time treatment. This video is for general education only. It is not medical advice. Ask your eye doctor what's right for you.
