What is a Yag laser capsulotomy?

A Yag capsulotomy is a special laser treatment used to improve your vision after cataract surgery. It is a simple, commonly performed procedure which is very safe. During your cataract operation, the natural lens inside your eye that had become cloudy was removed. A new plastic lens was put inside the lens membrane (called the bag or capsule) in your eye. In a small number of patients, the capsule thickens after surgery and becomes cloudy. This interferes with the light reaching the back of the eye. When this happens, your sight becomes misty, and you may get glare in bright light or from lights at night-time.

Capsule thickening can happen in the months after your cataract operation, but more commonly occurs about two years after surgery. Yag laser capsulotomy is the only way to treat this. Apart from affecting your vision, the thickening does not damage the eye in any way.

What are the benefits?

The laser treatment is to remove the cloudy capsule thickening in your eye, which aims to restore your vision to how it was after your cataract operation. 

Yag Capsulotomy Procedure.

You will have some drops put into your eye to make the pupil big, and an anaesthetic eye drop to numb the surface of the eye. You will then sit at a machine – similar to the one used to examine your eyes when you routinely visit the eye clinic – which has a special laser attached. The doctor will put a special mirrored lens on your eye before applying the laser beam. This lens allows the doctor to view the membrane clearly so he or she can apply the laser and make a small hole in it to clear the vision.

The treatment is painless due to the anaesthetic drops used to numb your eye before the laser and takes approximately 20 minutes. After the procedure, you will return to the waiting area. Your doctor or nurse may check the eye pressure about one hour later. He or she will then examine the eye to check the hole in the capsule. 


Are there any risks?

Complications after this treatment are very uncommon. Occasionally the opening made by the laser beam is incomplete, or not big enough. This will be discovered either after your treatment, or on your follow-up visit. If this is the case, it will be necessary to repeat the treatment at a later date.

Extremely rarely, some patients can get a build- up of fluid in the macula, the part of the eye responsible for detailed central vision. This build-up of fluid is called macular oedema (swelling), which causes blurring or distortion of vision. Another extremely rare complication is retinal detachment, when the fine light sensitive membrane at the back of the eye can come away from the wall of the eye.

The following symptoms mean that you need urgent treatment:

  • excessive pain
  • sudden onset of floaters (caused by small pieces of debris that float in the vitreous humour of the eye)
  • loss of vision
  • flashing lights
  • increasing redness of the eye.
