YAG Capsulotomy

One of the most common complications after cataract surgery is a posterior capsule opacity (also called posterior capsule opacification or PCO). During cataract surgery, the cloudy natural lens is removed and a new clear lens is put in place. The natural lens sits in a bag called the capsule and the new lens is placed in this same capsule during surgery. In about 20% of patients, this capsule can become cloudy due to migration of epithelial cells that are left over from the natural lens. A cloudy capsule can cause decreased vision and glare.

Fortunately, treating PCO is easy, quick, safe and painless. The treatment procedure is called YAG laser capsulotomy and can be performed right in our office. The cost is typically covered by medical insurance. Your surgeon will use a light laser to remove the clouded area of the capsule, creating a clear window and improving vision. As an added bonus, once this procedure is done it does not need to be repeated.


  • The affected eye is dilated
  • The patient sits in an exam chair behind a microscope where the YAG laser is attached. A gel is placed on the eye in order to focus the laser.
  • The surgeon applies the laser to the capsule and removes the cloudy area. The patient will hear clicks as the laser is activated.
  • The patient will not experience any pain or discomfort during or after the procedure.


  • The patient may resume normal activities immediately following the procedure.
  • Most people experience an improvement in their vision within a day.
  • There may be an increase in floaters, but these resolve within a few weeks. As always, call us right away if you notice a shower of floaters, flashing lights or a curtain over your vision as these could be signs of a retinal issue.
