YAG capsulotomy 

What is an ‘after-cataract’? 

A new prosthetic lens is inserted into the eye during almost every cataract operation. Ideally this new lens is supported in place by a skin in the eye called the ‘posterior capsule’. 

Unfortunately, over time, the posterior capsule can thicken, or become opaque, causing blurred vision. We call this posterior capsule opacification, or after-cataract. 

How do you treat after-cataract? 

After-cataract is treated by a special laser called a YAG laser. The laser acts by breaking apart the after-cataract (or posterior-capsule opacity), thereby clearing the obstruction to vision. The procedure is therefore called a ‘YAG capsulotomy’. 

The laser treatment only takes a minute and can be performed in the clinic with local anaesthetic eye drops. 

What can I expect afterwards? 

You may notice some transient blurred vision and floaters, but these usually settle. After that your vision should be similar to how it was immediately after your cataract surgery. 

You shouldn’t have any pain or permanently blurred vision after the laser treatment. If you do, please contact the clinic.
