YAG Laser Capsulotomy

What is a YAG Laser Capsulotomy? 

Following cataract surgery, the lens implant is surrounded by a capsule. In some patients, usually over months to years, this capsule can become thick or misty. This is called ‘posterior capsule opacification’ and can cause glare, blurred or misty vision. A YAG laser capsulotomy is a simple, quick and painless procedure to treat posterior capsular opacification. It is performed in the outpatient clinic, taking 5-10 minutes, and aims to restore your vision to how it was following your cataract operation. First, anaesthetic eye drops are administered to numb the eye and dilate the pupil. Then, the YAG laser is aimed at the rear of the lens capsule where it makes a small opening, enabling light to pass through, creating a clear visual pathway.

How long does it take for my vision to be restored following the YAG Laser Capsulotomy?

Patients will generally notice some visual improvement soon after the laser, however the final outcome will not be for 12-24 hours. Patients can go home straight away, however driving is prohibited from for the rest of the day.

What are the Side-Effects of YAG Laser Capsulotomy? 

Complications after this treatment are very uncommon. Extremely rarely, some patients can get a build- up of fluid in the macula, called macular oedema (swelling), which causes blurring or distortion of the central vision. Another extremely rare complication is retinal detachment. Some patients notice an increased number of floaters in their vision, but often this settles over time.

Are there any alternatives?

An alternative to a YAG laser capsulotomy is to do nothing. The capsule may or may not continue to thicken. If it does, you may wish to consider a YAG laser capsulotomy at a later date.
