Focal laser is a targeted retinal laser treatment used to seal or reduce leakage from specific abnormal blood vessels or microaneurysms, often in diabetic macular oedema.
When focal laser is used
In some patients, swelling in the central retina comes from limited areas of leakage that can be safely treated. Focal laser aims to dry these spots, stabilising or gently improving vision.
- Guided by detailed retinal scans and sometimes dye tests
- May be used alone or alongside intravitreal injections
- Avoids the very centre of the macula to protect fine vision
- Results often develop gradually over months
What to expect before and after
You sit at a laser machine after dilating drops, and a contact lens may be placed on your eye. The laser pulses are usually not painful but can cause momentary stinging or warmth.
- Vision may be slightly blurred or dazzled immediately afterwards
- Most people resume normal activities the same or next day
- Regular scans monitor changes in swelling and guide further treatment
- Good control of diabetes and blood pressure remains essential
