YAG Laser Capsulotomy

After cataract surgery, approximately 20% of patients develop a haze in the membrane behind the intraocular lens (IOL) implant following cataract surgery, which results in a decrease of vision. The vision may be blurred, hazy, or patients experience glare and loss of visual acuity. This condition, known as posterior capsule opacity, is sometimes referred to as “secondary cataract.” Cataracts, however, never recur following cataract surgery.

Posterior capsule opacity may be thought of as a scarring process in the capsule or bag, which contained the natural lens of the eye. The condition of posterior capsule opacity is not preventable, but fortunately, is treatable and nearly always restores or improves vision.

Posterior capsule opacity may be treated with a minor laser procedure known as a YAG laser capsulotomy. In this procedure, a laser is used to remove the hazy capsule located behind the IOL implant. This usually requires dilation of the eye before the procedure. The procedure takes only a few minutes, is entirely painless, and is not associated with any discomfort. Patients should anticipate some “floaters” following this procedure, however, these will likely resolve within a few weeks time.

Following a YAG laser capsulotomy procedure, patients may go resume normal activities immediately. Most patients may expect their vision to improve within a day of the procedure.

As with any eye procedure, patients should contact Dr. Sanders immediately if visual acuity worsens or fails to improve.
