Eliminating Cloudy Vision After Cataract Surgery
What is a YAG Posterior Capsulotomy?
The natural lens of the eye is situated in an elastic-like capsular bag that holds it in place. When performing cataract surgery, the surgeon carefully opens the front portion of the capsule in order to remove the lens. After completely removing the natural lens, the intraocular lens is positioned inside the capsular bag. The capsule holds the intraocular lens and serves as a protective barrier for the back of the eye.
Following cataract surgery, the capsule may develop a wrinkling or cloudiness that causes blurred or hazy vision. Some patients may also experience glare problems when driving at night. This common condition known as “posterior capsular haze,” occurs in as many as 40% of patients who undergo cataract surgery. And it may occur months or even years after cataract surgery.
What are the symptoms?
After cataract surgery, some people notice cloudiness in their vision, and it can become very dense and cause as much or more vision loss as the original cataract. Symptoms can include …
- Interference with daily activities
- Decreased vision
- Increased glare
The decision to have this procedure should be based on the same criteria as the decision to have the original cataract surgery:
- Vision problems are affecting your work or lifestyle.
- Glare caused by bright lights is a problem.
- You cannot pass a vision test required for a driver’s license.
- You have double vision.
- The difference in vision between your two eyes is significant.
How is a YAG Laser Posterior Capsulotomy Performed?
This laser looks just like the instrument used to examine your eyes in the office, putting your chin on a chin rest and forehead against a bar. Your eye has been mildly dilated and the treatment takes only 2-3 minutes. The laser makes a new clear opening for you to now look through that often restores vision back to what it was right after the original cataract procedure. There is no pain, eye patch, drops or restrictions afterwards.
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 and may expect your vision to improve within a day following the procedure. You may experience some floaters in your eyes over the next few days or weeks
After the procedure is completed, you will be required to return the next day for a quick follow-up appointment.
What results should you expect?
Serious complications with Yag Posterior Capsulotomy are extremely rare. Vision is generally improved in almost all cases with the exception of patients with other eye disease present.
