Glaucoma Laser Treatment (Selective Laser Trabeculoplasty)

Glaucoma Laser Treatment (Selective Laser Trabeculoplasty)

Selective Laser Trabeculoplasty (SLT), is a very safe procedure performed in the rooms of Dr Karagiannis. It is designed to lower eye pressure in glaucoma patients.

It can be used as an alternative to the use of daily eye drops or in conjunction with the use of eyedrops to further lower eye pressure.

How does it work?

With SLT, micro pulses of laser are applied to the drainage tissue of the eye. A reaction is created to allow more fluid to drain and lower the eye pressure. Often two treatments are required for each eye.

What happens during the procedure?

The laser procedure occurs in the rooms. Anaesthetic drops are instilled into the eye. It generally takes less than 5 minutes to perform, with the patient sitting upright and it is generally painless.


SLT is considered a very safe procedure and patients at most may develop a mild ache and or have mildly red eye for a few days.

Is it repeatable?

SLT can lower eye pressure very effectively in up to 75% of patients and can last up to 5 years.

It is considered a non-destructive procedure and therefore can be repeated safely, though the benefit of repeat treatment is variable.
