The procedure involves the application of contraction pulses Laser treatment is common in eye surgeries, and the argon laser is generally used for retinal therapy. Retinal Argon Laser treatment is recommended for conditions such as vascular diseases, diabetes, retinal breakages and macular degeneration. The laser stimulates the retina by creating heat in the retina through a precise focus to help swelling Argon laser therapy utilizes this technology to treat multiple gastrointestinal conditions including hemorrhages, dysphagia, mucosal lesions, and strictures. What are the Benefits of Argon Laser Therapy? Laser therapies in general, are more precise than other procedures which means the treatment is more focused on the damaged or problematic tissue. A YAG laser operates: via photo-disruption and the tissue is removed via this process.

What is an argon laser

Argon laser is used to prevent leakage of fluid from blood vessels at the back of the eye (the retina) or to prevent the development of abnormal blood vessels in the eye . 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.

What is an argon laser

Argon laser is a common laser used for treating DR. 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. Argon laser: A laser with ionized argon as the active medium. Argon lasers are used for photocoagulation in ophthalmology. The argon ion laser was one of the first lasers to be discovered following the invention of the laser and up until now it has been used extensively for Raman spectroscopy, among many other applications. Argon lasers are successfully used every day in everything form research and development to education, medical testing, image recording and more.

But in the wrong hands they can also cause serious burns and permanent scarring. In one recent study, To revisit this article, visit My Profi 15 Jun 2020 Definition of Argon Ion Laser. An Argon ion laser is a gas laser in which ionized Argon gas is used as the active or lasing medium. argon laser a laser with ionized argon as the active medium and with a beam in the blue and green visible light spectrum; used for photocoagulation. The argon ion laser is not quite as well understood, however much of the original work of E. I. Gordon, W. B. Bridges, and their coworkers [[10]], [[11]] can be used  Lumentum's argon lasers are designed for complex, high resolution original equipment manufacture (OEM) applications such as flow cytometry, DNA sequencing,  Argon (Ar+) laser efficiency. We see from the diagram in figure 1.4 that the lasing energy levels belong to the Argon ion, so the atoms of the gas inside the tube  The Tonks-Langmuir theory for the low-pressure positive column is reviewed and shown to be applicable to argon ion laser operation. Under these conditions  Argon ion laser contains a tube filled with Argon gas which transforms into plasma in an excited state.

Introduction In 1961, Zweng and Flocks introduced the concept of applying light energy to the anterior chamber angle for the treatment of glaucoma. In 1979, Wise and Witter described the first successful protocol of what has become known as laser trabeculoplasty Argon laser trabeculoplasty is an almost painless procedure in which laser light is directed to a delicate structure (the trabecular meshwork) where intraocular fluids normally exit the eye. Multiple laser bursts change this tissue in some, as yet mysterious way to greatly enhance the exit of the intraocular fluids.

ALT is for those: who have been diagnosed with glaucoma Argon laser lash ablation can be done as an effective office procedure with topical anesthesia. The advantages include low recurrence and complication rates in carefully selected patients and minimal postoperative discomfort. Argon laser trabeculoplasty (ALT) was introduced by Wise and Witter in 1979 for the treatment of medically uncontrolled glaucoma. Soon after its introduction, the efficacy and safety of this new technique was studied in a large multicenter prospective clinical trial funded by NEI, Glaucoma Laser Trial (GLT), in which eyes receiving ALT 360 degrees were compared with timolol monotherapy.
