Argon laser is used in ophthalmology for preventive care and treatment of vascular diseases of eyes: diabetic retinopathy, glaucoma, retinal veins thrombosis, Von Hippel-Lindau disease, Coats’ disease. Therapeutic effect is achieved with the help of short-term narrow-beam impact of laser ray in blue and green spectra on pigmented masses. The length of laser waves is between 488 and 514 nanometers, and that is why up to 70% of radiation is taken in by the dark pigment – melanin. The machine is quite large – it is up to 1 meter high. A water-filled radiator is used to cool the working environment. The output capacity of the machine is up to 20 watt.
The advantages of use of the given ophthalmology equipment are:
The ophthalmic device effects the pigmental tissues, softly burning them off. Microscopic scars are formed, but they do not influence the patient’s visual acuity. The laser is used to burn off vascular pathologies, to reduce the consequences of mechanical injuries, to heal the detached retina, to remove the yellow spot and small neoplasms. Positive results of treatment are achieved through denaturation and coagulation of tissues containing melanin. Argon lasers are equipped with replaceable LEDs and attachments.
Argon-ion lasers emit at 13 wavelengths through the visible and ultraviolet spectra, including:
The most important technical characteristics of such devices are: 1) Wavelengths: 488 nm and 514.5 nm. Wavelength selection module should be provided to select one wavelength at a time. 2) Minimum output laser power:- ≤ 20 mW for both the wavelengths 488 nm and 514.5 nm and maximum output laser power:- ≥ 40 mW for both the wavelengths 488 nm and 514.5 nm. There should be provision for adjusting the laser power. 3) Cooling method: air cooled 4) Mode: TEM00 5) Beam divergence: ≤ 1.25 mrad 6) Polarization: linear, ≥ 100:1 7) Output power stability (over 2 hour period after warm up): ± 2% 8) Operating temperature: 20 °C to 40 °C 9) Beam pointing stability (over 2 hour period after warm up, ± 2 °C ): ≤ 30 µrad 10) Input operating voltage : 230 VAC ± 10% at 50 Hz
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. The manufacturer plays a crucial role in making up the argon laser price. The more famous the brand the more expensive the machine, as the brand name itself says a lot about the quality and longevity.IRIDEX,COHERENT,ELLEX,LUMENIS ,NIDEK are considered to be the most well-known. Besides, one should understand that new and demo machines will cost more than refurbished or used argon laser. What is the difference? New machines have never been used. They have the manufacturer’s warranty. Demo machines are, as a rule, exhibition models. They have not been used in clinical practice but they have been often presented at exhibitions. As a result, the price is lower. Refurbished machines are used machines that have undergone improvements (refurbishment can be done at the manufacturer’s facilities or in private repair shops)
