The most common complication of cataract surgery is clouding of the part of the lens covering (capsule) that remains after surgery, called posterior capsule opacification. If the cloudiness affects your vision, you may choose to have a laser surgery called Nd:YAG posterior capsulotomy to correct this problem.
The doctor will apply topical anesthetic (eyedrops) so that you won’t feel pain. Then he or she will use a laser (Nd:YAG laser) to cut a hole in the clouded back lining of the lens capsule. This allows light to pass through the membrane to the retina at the back of the eye.
Why It Is Done
After cataract surgery, some people notice cloudiness (sometimes called aftercataract) after several months or years. In some people, it can become very dense and cause as much or more vision loss as the original cataract
- 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.
- You have another vision-threatening eye disease.
The procedure is not needed unless vision loss caused by clouding of the lens capsule is seriously affecting the person’s vision and lifestyle.
