YAG Laser for Secondary Membrane
After Cataract Surgery (Capsulotomy)

What is a “secondary membrane”?

The natural lens of the eye is enclosed in a clear, cellophane-like membrane called
the capsule. During cataract surgery the front of the capsule is opened. The cloudy
lens inside the capsule is removed. In most cases, the back of the capsule is left in
one piece, and a plastic lens implant is put in place in front of the capsule. In some
patients, the capsule can become thickened and cloudy over time. This may happen
a year or more after surgery. It is this thickened capsule that is called a “secondary
membrane.” You may notice a slow decrease in vision, problems with glare, or
things might look slightly hazy. If this becomes a problem, your doctor may
suggest a YAG laser treatment to help clear your vision.


What does the laser treatment involve?

The YAG laser is used to create a small hole in the center of the remaining capsule.
You will first receive drops to dilate your pupils and to prevent a rise in your eye
pressure. It takes 30-60 minutes for the drops to take effect. The laser treatment is
then done in the clinic. The laser machine looks much like the slit lamp that the
doctor has used at your visit. Just before the laser treatment, you will receive a
numbing drop in your eye. A focusing contact lens will be placed on the eye. The
treatment takes about 10 minutes and is not painful. Most patients say that they feel
a slight “pop” or “shock” in the eye, but that it does not hurt.

Your eye pressure may be checked either right after the laser treatment or one to
two hours later. Your eye may feel scratchy or seem blurry for the rest of the day,
but should be back to normal by the next morning.










Are there any risks with laser treatment?

The risks of the laser treatment are few. The laser can cause the eye pressure to rise
during or after the treatment. You will be given a drop before the treatment to help
prevent this. We could nick or damage the lens implant if it is hit directly with the
laser. This rarely affects your vision. There could be slight inflammation in the
eye. You will be given a prescription for medicine to take to reduce this. You may
notice an increased number of floaters in your eye. Laser treatment can also
slightly increase the chance of having a detached retina.


What happens after the treatment?

Because your eye will be dilated, you may notice blurry vision for about 4 hours
after the treatment. You may feel better wearing sunglasses, particularly in the
bright light. Your eye may be scratchy for the rest of the day. There are no
restrictions on what you can do.

Your doctor may give you a prescription for a drop to use four times a day for 5
days after the laser treatment. This drop helps prevent inflammation in the eye.

If your eye becomes painful or if you have a decrease in vision, call the clinic.
