YAG laser treatment is used usually to improve vision after cataract surgery, when the clear capsule behind the new lens becomes cloudy with time. It is also used occasionally to improve drainage in patients who are at risk of developing a type of glaucoma called narrow angle glaucoma.
The following information concerns the use of YAG laser treatment for improving vision after cataract surgery.
When the capsule behind the lens becomes cloudy, the symptoms of blurred vision and glare can return, and are similar to those experienced with the original cataract.
YAG Laser treatment
The procedure is performed in the outpatient clinic in a seated position. You should not drive to the clinic, as dilating drops will be placed in your eyes. Mr Ismail will examine your eyes and determine whether you will benefit from the treatment in one or both eyes. Treatment is performed one eye per session. This may be at the same clinic appointment as your consultation if there is time, or may require a return. Once the dilating drops have been placed, you will have the laser treatment.
The treatment usually lasts 2-5 minutes, and is not painful. After treatment, there is no requirement for any restrictions on activity, and you will be asked to return to the clinic in a few weeks for a review of your eyes. In most cases, the visual improvement is very quick, and often is noticed straight after the treatment.
What are the risks?
The vast majority of patients undergoing YAG laser treatment after cataract surgery have an excellent visual outcome.
There is a small risk that your sight will not be better after the procedure. This may be due a preexisting problem with the eye. Rarely there can be damage to lens in the eye or a problem with the retina such as fluid accumulation or retinal detachment.
In general, the risks of YAG laser treatment are much lower than those of cataract surgery (which are already low)
