About Retinal Laser Photocoagulation

What is Retinal Laser Photocoagulation?

Retinal laser photocoagulation is a treatment we use at Vasan to address several retina-related issues such as diabetic retinopathy, retinal vein occlusion, and others.

Contrary to popular belief, it’s not a surgery. Our specialist directs a laser beam to the targeted area on the retina, generating heat to achieve retinal coagulation for treatment.

When / Why do I need it

When do I need it?

Retinal Laser Photocoagulation is employed along with other treatments to treat many retinal issues. You could need it when undergoing treatment for the following disorders.

Proliferative Diabetic Retinopathy (PDR):

Laser therapy, known as pan-retinal photocoagulation (PRP), is vital to prevent complications like bleeding or detachment in advanced diabetic retinopathy.

Diabetic Macular Edema (DME): 

Retinal Laser treatment targets leaky blood vessels to reduce swelling and preserve vision in DME.

Retinal Vein Occlusion (RVO): 

Retinal Laser therapy improves blood flow and manages RVO by reducing the risk of complications.

Retinal Tears, Holes, and Degeneration: 

Retinal Laser treatment reduces the risk of retinal detachment by creating adhesion around tears and thinning areas.

Central Serous Chorioretinopathy (CSC) and Choroidal Neovascularization: 

Retinal Laser therapy may prevent further damage by targeting leaky areas in these conditions.

How our experts treat it

Before our experts start with the laser procedure, we apply some topical anaesthesia to keep you comfortable. Don’t worry; we’ll also use eye drops to minimise any discomfort during the procedure. It’s usually pretty quick, taking anywhere from 5 to 20 minutes, depending on what we’re treating and your specific condition.

There are 2 types of Retinal Laser Photocoagulation.

Contact method:

With the contact method, we will keep a lens with some gel over your eyes while you're sitting comfortably.

Non-contact method:

In the non-contact approach, you'll be lying down, and we'll deliver the laser therapy accordingly. Occasionally, we might apply a little pressure around your eyes with a handheld tool to ensure everything goes smoothly.


Retinal photocoagulation, also known as laser surgery, boasts a success rate of over 90%. Here’s how it works: our expert directs a powerful laser beam onto the damaged or torn part of your retina, effectively treating the issue with precision.

Pan retinal photocoagulation (PRP) is a laser eye treatment targeting abnormal blood vessels located at the back of the eye, specifically in the retina’s drainage system. This procedure effectively treats these vessels, promoting better eye health and function.

Recovery from retinal photocoagulation typically takes a couple of hours, though it might take a couple of weeks for the effect to come. During this time, it’s normal to experience ongoing light flashes or floaters, as the treatment gradually seals the retinal tear.

Laser photocoagulation typically lasts from a few minutes to 30 minutes, depending on the required extent of treatment. After the procedure, patients may experience blurred vision in the treated eye, so driving is not recommended for several hours. However, they can usually return home immediately following treatment.
