YAG Capsulotomy

What is YAG Capsulotomy?

YAG capsulotomy is a laser procedure that is used in the treatment of posterior capsular thickening, which can occur after cataract surgery.

During cataract surgery, the cloudy lens of the eye is removed and replaced with a clear plastic lens, which rests on a transparent membrane called the posterior capsule.

Once removed, the cataract will not come back, but in some patients the capsule itself can thicken and become opaque over time making vision hazy.

Posterior capsular thickening can happen any time after your cataract operation from a few months to years. YAG capsulotomy is performed to restore your vision to how it was immediately after the cataract operation.

How is YAG Capsulotomy Performed?

YAG capsulotomy is performed in the office under topical anaesthesia. Your doctor first checks your vision and instils drops to dilate your pupils. To keep the eye open and focus the laser beam, a special contact lens is placed on the eye. Your doctor then uses a laser beam (Ellex Tango) to create a small opening in the clouded capsule, in order to provide a clear path through which light can pass. You will hear beeping noises and experience bright lights during the process, but the procedure is completely painless. The whole procedure lasts for approximately 1 to 2 minutes. Your vision should improve almost straight away, though you may notice a few "floaters" in your vision for a few days.
