YAG Laser

Posterior Capsular Opacification

This picture shows a clear lens in the eye after cataract surgery. There is no clouding of the capsule in this picture. 

Opacification of the Posterior Capsule  [PCO] is common after cataract surgery and typically happens in all patients.

 It is the commonest complication of cataract surgery occurring in up to 50% of patients by 2 to 3 years after the operation.  

Posterior Capsular Opacification is also known as PCO or Secondary Cataract and the is cured by a YAG laser treatment.


Painless treatment with a YAG laser will quickly restore vision if you develop posterior capsular opacification.

During cataract surgery, Dr. Duplessie dissolves the cataract with a phacoemulsification device and replaces your natural lens with an artificial lens.  PCO refers to clouding and thickening of the back (posterior) of the lens capsule which holds your artificial lens in place. This thickening of the capsule causes your vision to become cloudy due to thickening the membrane that held the human lens in place.  As much as your lens became cloudy and became a cataract; the membrane holding it in place has become cloudy and become PCO.


YAG laser Treatment for Treating Posterior Capsule Opacity

Fortunately, a YAG laser can treat posterior capsule opacity safely, effectively and painlessly. A YAG laser treatment is performed in Dr. Duplessie’s office.



YAG laser capsulotomy

Completely painless and quick:

  • The eye to be treated is dilated with dilating eye drops.
  • You stare straight ahead and you will hear a clicking sound
  • The procedure is painless and lasts just a few seconds

There are no restrictions after a YAG laser, so you can resume normal activity.

You will see floaters which will disappear with time.

Only one YAG laser treatment is typically required.


YAG Laser Treatment  Risks

All procedures have risks.  A YAG laser is extremely safe. There is a slightly increased risk of retinal detachment.  If you notice an increase in floaters, flashing lights or decreased vision, please contact Dr. Duplessie immediately.
