If you have had cataract surgery in the past or are getting ready for such a procedure, you should know that some people need to go back to their surgeon for an additional procedure. While this secondary visit is far simpler and may not always be necessary, it's good to understand why it may sometimes be required, so you can always be aware. What do you need to know about capsule surgery, also known as a capsulotomy?
Focusing on the Capsule
When the surgeon conducts a cataract procedure, they remove the natural lens and replace it with an artificial version. This lens sits inside a capsule, which will continue to perform the same function for the new lens as it did for the old.
This capsule has a clear surface to allow the light to pass through, but it may start to become thicker and cloudier in some patients. When this happens, it can lead to hazy and blurred vision, which will gradually come on over time.
Scientists invented a special laser called a YAG to deal with this situation. The name comes from the specific type of crystal used within the machine (the yttrium aluminium garnet). This laser can be used to clear part of the capsule so that it does not interfere with vision anymore, restoring the same level of vision as the patient had immediately after the cataract procedure.
During the Procedure
When you present for this procedure, you will simply need to place your head onto a chin rest as you would for a normal eye examination. After adding dilating eye drops, the surgeon will point the laser machine at the capsule, and you will hear several clicking noises as the procedure gets underway. Some people report that they feel a small tapping sensation on the back of the head, which is perfectly normal.
Typically, this procedure is over in a matter of minutes, although the vision may be affected by the bright light that comes out of the laser machine. Usually, it should return to normal within a short amount of time, while you may notice a significant difference right away. Otherwise, you should certainly notice an improvement within a few hours and after the dilating drops start to wear off.
Talking with Your Surgeon
So, if you've noticed that things have become blurry in the eye with the replacement lens, talk to your surgeon. They will recommend an appointment, as you may benefit from a YAG procedure.
