What is Panretinal Photocoagulation?

​

 

Panretinal Photocoagulation (PRP) is a laser treatment used to manage abnormal blood vessels that develop at the back of the eye or within the eye’s drainage system.

During the procedure, small laser spots are applied to specific areas of the retina. This helps the abnormal blood vessels shrink and eventually disappear. By doing so, PRP reduces the risk of bleeding inside the eye and helps prevent painful complications caused by fluid build-up and increased eye pressure.

What happens on the day of your treatment?

​

 

• You will meet with a member of the clinical team who will test your vision and administer eye drops to dilate your pupil. Numbing drops will also be used to keep your eye comfortable.
• You’ll sit at a laser machine similar to the one used during a regular eye examination. A special contact lens is placed on your eye to help focus the laser.
• Your eye specialist will then perform the laser treatment, which usually takes 15–30 minutes per eye. Most people feel only mild discomfort — sedation is not required.
• During the procedure, you may see bright flashes of light and feel slight stinging or pressure.

What can you expect after Panretinal Photocoagulation Laser?

​

 

After the procedure, it’s normal to experience mild and temporary effects, including:
• Blurry or hazy vision for several hours
• Light sensitivity — sunglasses can help
• Mild discomfort or a dull ache

If you notice any of the following, contact your eye specialist promptly:
• A sudden drop in vision
• Severe or increasing eye pain
• Significant redness or discharge
• New flashes or a sudden increase in floaters

Your eye specialist may prescribe anti-inflammatory eye drops to reduce inflammation and swelling.

Most people recover quickly and can return to normal activities soon after treatment, but avoid driving until your eye specialist confirms it is safe to do so.

Are there any risks?

As with any medical procedure, PRP laser treatment carries some risks and side effects. These may include:

• Blurred vision
• Reduced night or peripheral vision
• Mild discomfort or soreness
• Temporary increase in floaters

These effects are usually mild and resolve quickly. Serious or long-term complications are rare
