Focal laser treatment

Focal laser treatment

Your condition

The retina is a layer at the back of the eye that is responsible for vision. With diabetic retinopathy your retina may go through a series of changes. These may include leakage or closure of capillaries (tiny blood vessels) or growth of weak, new capillaries. These changes may progress in severity leading to reduced vision.

Diabetic retinopathy is best managed with good blood pressure and blood glucose control.

What does the laser do and how does it work?


This type of laser treatment is performed using a thermal laser. Focal laser is targeted at specific areas of the retina to seal up these leaking blood vessels. The amount of laser burns to the retina varies, depending upon the severity of your retinopathy.

What to expect?

  • You will have pupil enlarging eye drops instilled.
  • Local anaesthetic drops will also be instilled before the procedure.
  • Treatment is delivered through a lens that rests against the eye.
  • If you have diabetes please ensure you have your normal meals and bring snacks for while you wait.
  • Side effects may include slight discomfort and sensitivity to light (photophobia). Wearing sunglasses (with your prescription, if required) can make the trip home more comfortable.
