What is Argon Laser?

It is a laser system that uses noble gas as an active medium. Argon laser has been applied as a therapeutic agent in ophthalmology for more than 50 years.

How does Argon laser work?

A device emits wavelengths of blue, red, yellow, or green light, which is a monochromatic source. Each beam has a very narrow range. In ophthalmology, argon laser is mostly applied to retinal diseases as well as glaucoma.


  • Retinal tear
  • Diabetic retinopathy
  • Retinal vein occlusion
  • “Extrafoveal” choroidal neovascularization
  • Glaucoma

Treatment with Argon laser

The laser light beam penetrates the anterior tissues without causing them damage. Focusing on the posterior pole of the retina essentially causes a mild reaction to avoid retinal detachment, bleeding in the vitreous, neovascular glaucoma, etc. The result of laser treatment is permanent. Usually only one session is required if it is a retinal crack and up to 3-4 sessions if it is severe diabetic retinopathy or other vascular disease.

How is Argon laser performed?

Treatment is carried out with administration of only anesthetic drops, in a seated position. Its duration rarely exceeds 10 minutes. After treatment usually it is not necessary for the patient to take any treatment or protective measures.
