Understanding YAG Capsulotomy

Normally after cataract surgery your vision should be very clear but in some cases your vision can become cloudy, like it was prior to surgery. This is not a new cataract forming. It is something called a secondary membrane that begins to accumulate around the intraocular lens, causing a blurring of vision similar to that which one experiences with a cataract. Approximately 20% of patients who undergo cataract removal will eventually experience this type of blurry vision. The average time for this to happen after cataract removal is about two years, but it can happen as early as three months, or as late as five years.

There is a very easy way an ophthalmologist can clear this cloudy pupil and restore your clear vision. A non-invasive laser treatment, called a YAG capsulotomy, can be performed. YAG refers to the type of laser (Yttrium Aluminum Garnet) for this procedure. This procedure takes only a few minutes, can be performed in the ophthalmologists office, is completely painless, and does not involve any type of anesthesia. It does not cause discomfort afterwards, and patients can resume normal activities immediately. Most patients will notice an improvement in vision immediately.
