What is it?
Cyclodiode laser treatment causes cyclodestruction, destroying a portion of the ciliary body, a structure in the eye which produces aqueous fluid. This can reduce the amount of fluid produced and therefore reduce pressure inside the eye. The laser energy is directed to the ciliary body via a probe that is held against the wall of the eye.
How does it work?
If the natural (aqueous) fluid that fills the eye cannot drain away properly, it can result in a build-up of pressure within the eye. The high pressure can cause loss of vision and, if very high, pain or discomfort. Cyclodiode laser treatment works by reducing the amount of aqueous fluid produced and therefore reduce pressure inside the eye.
Who is it suitable for?
This procedure is most commonly used on eyes where other forms of surgery would be difficult or likely to fail. Although the treatment is usually effective, more than one treatment is sometimes required. The aim of glaucoma treatment is to reduce the pressure to a level which is safe for the eye.
What are the benefits?
In some patients, cyclodiode laser treatment can have the additional benefit of reducing pain from high pressure.
This procedure DOES NOT improve your vision.
Before the procedure
Please take all medication as normal or as instructed. Your eye specialist (ophthalmologist) will advise you on which of your eye drops to use after the procedure.
During the procedure
This procedure is usually carried out under local anaesthetic. This means that although you will be awake, the eye will be numb so you will not feel any pain. You do not usually have to stay in hospital—the procedure itself lasts approximately 15 minutes and is carried out in the operating theatre.
After the procedure
What are the risks?
Any medical treatment involves potential risks. Some of those which apply to this procedure are:
Are there any alternatives?
Cyclodiode laser is one of many glaucoma treatments, including eye drops, drainage surgery and other types of laser. Typically, if your Ophthalmologist recommends the use of cyclodiode laser, then alternative treatment options have proven ineffective, or have been deemed inappropriate. Having an understanding of why cyclodiode is appropriate for you – through discussion with your Ophthalmologist – is recommended.
