One of the most common occurrences following cataract surgery is the reappearance
of cloudy vision. Many patients experience a condition known as Posterior
Capsule Opacity (PCO) weeks, months or even years after surgery.
The condition is also referred to as “secondary cataract” and
impairs your vision. It is most effectively treated with a quick, painless
YAG laser treatment.
What is Posterior Capsule Opacity?
The eye’s natural lens is held into place by an elastic-like capsular
bag. When performing cataract surgery, the surgeon will open the front
portion of the capsule and remove the natural lens. Once removed, it will
be replaced with an intraocular lens. The capsule will both hold and protect
the intraocular lens from the back of the eye.
Following cataract surgery, the capsule may develop cloudiness that causes
blurred or hazy vision. Some patients may also experience glare problems
when driving at night. It is normal to have much improved vision after
healing from cataract surgery, and then sometime later, noticing some
or all of the following:
• Blurriness or haziness affecting your daily activities.
• Trouble driving because of glare from the sun or bright oncoming
To treat these symptoms, your eye doctor will perform a quick laser procedure
What is YAG Capsulotomy?
The YAG Laser used to treat post-capsular haze looks just like the instrument
used to examine your eyes in the office. You will be asked to put your
chin on a chin rest and forehead against a bar.
Your eye will then be mildly dilated and the YAG laser will create a new
clear opening in the back of the capsular bag for you to look through.
How long does the procedure take?
YAG Capsulotomy is a quick procedure that lasts only two to three minutes.
You will be asked not to rub or touch your eye for 30 minutes after the
procedure, as that may cause a corneal abrasion. You can also expect to
remain at your doctor’s office for about an hour to ensure no other
complications (such as increased eye pressure) arise. You will be asked
to return for a checkup within one to two weeks after treatment.
Is YAG Capsulotomy effective?
For most patients, YAG Capsulotomy restores vision to what it was immediately
after the original cataract procedure. There is no pain, eye patch, drops
or restrictions afterward.
Most patients notice an instant improvement in their vision, while others
experience a gradual improvement over several days. Following a YAG Capsulotomy,
you may resume your normal routine immediately. It is normal to notice
some floaters in your eyes over the next few days or weeks, which should subside.

affecting your daily activities or difficulty driving due to glare, contact
