What is an argon laser used for?
What is an argon laser used for?
Argon laser treatment can be used to treat a number of eye conditions including glaucoma, diabetic eye disease and some retinal holes and tears. It can also be used to prevent an eye condition from getting worse, and sometimes to cure it.
How much does an argon laser cost?
How Much Does Laser – Argon Cost? The prices of some systems can be as low as 500 USD or less, while the newest, high-tier systems may cost as much as 30.000 USD.
What are the values of wavelength of argon laser?
Explanation: The wavelengths of Argon laser used in LBM range from 330 – 530 nm.
Does laser photocoagulation improve vision?
Laser photocoagulation is done to reduce the risk of vision loss caused by diabetic retinopathy. It is most often used to stabilize vision and prevent future vision loss rather than to improve vision loss that has already occurred.
Is laser photocoagulation surgery?
Laser photocoagulation is a type of laser surgery for the eyes. It is done to treat age-related macular degeneration (AMD). AMD is a condition that can lead to loss of vision.
Why is argon laser used in eye surgery?
It improves the drainage of the aqueous humor (eye fluid). Repairing retinal tears and small retinal breaks: Small tears in the retina in individuals with high myopia or other diseases can be repaired with an argon laser. This prevents the risk of retinal detachment in the future.
What kind of laser is argon?
Argon laser The argon-ion laser was invented in 1964 by William Bridges at the Hughes Aircraft Company and it is one of the family of ion lasers that use a noble gas as the active medium. Argon-ion lasers are used for retinal phototherapy (for the treatment of diabetes), lithography, and the pumping of other lasers.
What is argon ion laser?
What is the wavelength of argon?
The main spectral peaks of the argon laser are 488 nm (blue) and 514 nm (green) i.e. relatively shorter wavelengths.
What are the spectral peaks of the argon laser?
The main spectral peaks of the argon laser are 488 nm (blue) and 514 nm (green) i.e. relatively shorter wavelengths. Modern argon lasers remove blue wavelength light, allowing photocoagulation to be achieved at 514 nm which reduces light scatter as well as preventing absorption of the blue 488-nm wavelength by xanthophyll in the macula.
Why is argon photocoagulation inferior to laser and APC?
It is considered inferior to laser and APC because of its inability to cover large areas, thereby creating the need for multiple treatment sessions (7). A recent pilot study (12) reported on the use of endoscopic cryotherapy using carbon dioxide to successfully treat GAVE lesions in 12 patients.
Which is better for photocoagulation argon green or argon blue?
It protects the photoreceptors from short-wavelength light damage, but can be damaged by blue light which is why Argon green is preferred in macular photocoagulation over Argon blue. Absorption varies according to oxygen saturation.
Which is the best laser for macular photocoagulation?
For example, Diode laser with wavelength of 810 nm can penetrate deeply into the choroid. Located in the inner and outer plexiform retinal layers. It protects the photoreceptors from short-wavelength light damage, but can be damaged by blue light which is why Argon green is preferred in macular photocoagulation over Argon blue.
