Cyclodiode Laser Treatment
If the natural (aqueous) fluid which fills the eye cannot drain away properly, it can result in a buildup of pressure within the eye. The high pressure can cause loss of vision and, if very high, pain or discomfort. The aim of glaucoma treatment is to reduce the pressure to a level which is safe for the eye. If eye drops fails to reduce the pressure, damage to the delicate optic nerve will eventually cause permanent loss of sight. However, there are other options to reduce the risk of this happening.
Cyclodiode laser treatment
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. 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.
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
The eye may be covered with a pad after the operation which you should leave on until you get home. It is not advisable to drive on the day of the procedure.
Your eye may be uncomfortable for a few days after the procedure – this can usually be controlled with products such as paracetamol. The eye may also be watery and gritty for a few days and the vision may be blurred. You may be given some new drops to use initially to reduce inflammation in the eye. It is important that these drops are used as directed. Your ophthalmologist will advise whether you should continue your usual drops or stop them.
You will usually have a check-up appointment within 1 month of treatment to monitor your response to the laser treatment.
What are the risk and benefits?
Any medical treatment involves potential risks. Some of those which apply to this procedure are:
Although the risks may sound worrying it is important to remember that cyclodiode laser treatment is generally successful and well tolerated.
In some patients, cyclodiode laser treatment can have the additional benefit of reducing pain from high pressure.
This procedure DOES NOT improve your vision.
