Retinal Laser Treatment


Laser treatment uses focused light, tuned to specific wavelengths, different intensities, and varying duration. The energy is focused on the retinal tissue with an extremely high level of precision and accuracy. Heat is generated by the light energy which produces a reaction at the desired location.

Are All Lasers The Same?

No, there are many different types of laser used in Ophthalmology and for varying purposes.

Prof. Stanga has pioneered new laser technologies such as the Pascal® laser and treatment techniques specifically for use in retinal procedures. When needed, he will discuss which one would be best for you.

What Happens During The Treatment?

Once you arrive, a nurse will give you eye drops to dilate the pupil of the eye to be treated. The dilating drops may cause a slight blur to the vision which can last around 4 hours depending on the patient.

Prof. Stanga will re-discuss your treatment plan and the consent form will be signed. This is another opportunity to ask any further questions you may have following the previous consultation.

Anaesthetic drops will be put into your eye before treatment. There may be a slight stinging sensation from the drops, but this is normal.

A contact lens is then placed onto the front of your eye. This may feel abnormal but is not painful.

What Happens During Retinal Laser Treatment?

You may see: Flashing lights

You may hear: Clicking noises

You will need to listen carefully to Prof. Stanga’s instructions to look in different directions, so the laser can be focused on the area of the eye which needs to be treated.

Due to small nerves which may run across the treatment area, some patients may experience discomfort which usually lasts no longer than a couple of seconds.

Effect On Your Vision After The Laser Treatment

The vision may be hazy and blurred for the first 24 hours after treatment. When large areas of the peripheral retina are treated, your peripheral vision may be permanently reduced. This may affect your ability to drive and also meet DVLA Driving Standards. We ask you to not drive to the clinic on the day of treatment as you will not be able to drive home.

Some patients may require Combination Treatment of Retinal Laser and Intravitreal Injections.

We also advise you to wear sunglasses when going home, to help with dazzling daylight.

Night and colour vision may also be permanently affected.

If you subsequently develop macular oedema or diabetic maculopathy, Prof. Stanga may prescribe anti-inflammatory drops or offer an intra-ocular injection to reduce the swelling.
