The laser is applied to the drainage areas of the eye with typically around 30-60 laser shots per eye at a time. You may see a bright red light and you may feel a mild tingling sensation with each eye laser shot. 1. Retina. 1984 Spring-Summer;4(2):126-8.

Argon Laser Trabeculoplasty (ALT): WHEN: This has now been almost entirely replaced by selective laser trabeculoplasty (SLT) which is equally effective but leaves no damage to the eye tissues (Kent et al. 2015; Juzych et al.

The information presented is intended to demonstrate an Argon Medical Devices, Inc. product. A physician must always refer to the package insert, product label and/or instructions for use, including the instructions for cleaning and sterilization (if applicable), before using any Argon Medical Devices, Inc. product. The 85 and 95 Argon Ion lasers have over a 45 years history of the highest quality and performance. A simple solid BeO ceramic plasma tube is the best value and reliability in a 1- 7watt gas-ion laser. A typical high-power argon ion laser, containing a tube with a length of the order of 1 m, can generate 10 W or 20 W of output power in the green spectral region at 514.5 nm or a couple of somewhat shorter wavelengths It requires several tens of kilowatts of electric power. Overall laser construction is not that much more complex than a HeNe laser, hence unit costs are considerably lower than low-power argon ion lasers which also provide output in the blue. Usually Brewster angle windows are provided together with a high Q stable resonator (97–99% reflectivity output coupler) to provide polarized output.

It is also more cost-effective than other alternatives. What is Argon Plasma Coagulation (APC)? Many people mistakenly believe that APC is another type of laser treatment. It is not. Instead, APC uses the combination of argon gas and a high-voltage spark. Like lightening, this activated gas spark wants to find a ground in the nearest tissue.

Eisner A, Chenoweth RG. Filtration of argon laser light to eliminate the blue wavelengths and create a green-only light may be clinically useful in treating macular lesions. Characteristics of Ar-Laser All ion laser(such as argon , krypton and mix gas) produce several different wavelengths Argon laser produce wave nine different wavelengths in which two are most powerful and commonly used. Argon laser are operated in continuous wave mode to get very rapid , short duration pulses. For Argon Laser the output power can ranges from few mill watts 20 watts 5

Its cost is not as low as He-Ne laser type. Argon Laser Trabeculoplasty (ALT) Although your eye care professional may suggest ALT surgery at any time, it is often performed after trying to control intra-ocular pressure with medicines. In many cases, you will need to keep taking glaucoma medications even after ALT surgery.Laser surgery has become increasingly popular as an intermediate step between drugs and traditional glaucoma surgery. 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.

Disadvantages of Argon laser. The overall efficiency of argon laser is very less usually lies between 0.01% and 0.1%. Large amount of power requirement is also its disadvantage. Construction is very difficult. Cost of argon laser is not as low as He-Ne laser. 2020-06-15 Argon Lasers Characteristics. Compact design!
