<\/span><\/h2>\nThe argon ion laser emits a specific wavelength (488\u2013514 nm) of blue-green light that is in the visible portion of the electromagnetic spectrum. About 80% of the energy is at wavelengths of 488\u2013514 nm.<\/p>\n
The excitation medium is ionized argon gas in a sealed laser tube, which is excited by a direct electrical current. download<\/span>.<\/p>\n\n

<\/span>How does the argon laser work?<\/span><\/h2>\n\n- The argon laser, when used for dermatological applications, works on the principle of selective thermolysis.<\/li>\n
- The selected wavelength of the laser light is highly absorbed by the target structure (called chromophore<\/span>) compared to the surrounding tissue.<\/li>\n
- This ensures that the impact of thermal energy is limited to the target structure and does not affect the surrounding tissue.<\/li>\n
- When laser light hits the skin, it is reflected, transmitted or absorbed.<\/li>\n
- The absorbed energy is most responsible for the clinical effect because the intended targets convert it into thermal energy (heat) (chromophores<\/span>), thus destroying diseased cells.<\/li>\n
- The skin chromophores commonly targeted by the argon laser are hemoglobin<\/span>, melanin<\/span> pigment<\/span> and water.<\/li>\n
- Complications occur when energy destined for the target chromophore diffuses and is non-selectively absorbed by surrounding tissues and structures.<\/li>\n<\/ul>\n
<\/span>What is the argon laser used for?<\/span><\/h2>\nThe United States Food and Drug Administration (FDA) has approved a range of argon laser machines for various skin disorders. These include The LASOS\u00ae<\/sup> Ar-Ion lasers (LASOS Lasertechnik, Germany) and Modulaser\u2122 <\/sup>(Modulaser, Utah, USA). Individual machines are designed to treat specific skin problems.<\/p>\nThe following skin disorders can be treated with argon lasers.<\/p>\n
\n- Vascular<\/span> malformation<\/span><\/li>\n
- Telangiectasia<\/span><\/li>\n
- \nAngioma<\/span>\n<\/li>\n
- Venous<\/span> lake<\/li>\n
- Pyogenic<\/span> granuloma<\/span><\/li>\n
- Tattoo<\/li>\n
- \n
Keloid scar<\/span>\n<\/li>\n- Epidermal<\/span> nevus<\/span> <\/li>\n
- Angiokeratoma<\/span> <\/li>\n
- Warty<\/span> hemangiomas<\/span><\/span><\/li>\n
- Xantelasma palpebrum<\/li>\n<\/ul>\n
Argon lasers are approved by the FDA for use in photodynamic<\/span> therapy to treat actinic keratosis<\/span><\/span> and basal<\/span> cell carcinoma<\/span> (BCC)<\/p>\n\n- Photodynamic therapy uses a combination of light energy and a photosensitizing agent (a medication that is activated by light).<\/li>\n
- The photosensitizing agent is injected into the blood or applied directly to skin lesions. Pick up more at Cancer<\/span> cells than in normal cells.<\/li>\n
- When the laser light is focused directly on tumor<\/span>, cancer cells absorb the light and a chemical reaction occurs that destroys the cancer cells.<\/li>\n
- In the case of BCC, the light-sensitizing agent is current<\/span> 5-aminolevulinic acid (5-ALA) or methyl aminolevulinic acid, which is applied topically to the injury<\/span>.<\/li>\n
- The medicated area is then activated by argon laser light, which selectively destroys BCCs while causing minimal damage to surrounding normal tissue.<\/li>\n<\/ul>\n
<\/span>What are the advantages of argon laser therapy?<\/span><\/h2>\n\n- Lasers are more precise than standard surgical tools (scalpels), so they do less damage to normal tissues.<\/li>\n
- With laser therapy, surgical procedures are typically shorter and can often be performed on an outpatient basis.<\/li>\n
- Patients take less time to heal after laser surgery and are less likely to get infections.<\/li>\n
- Low cost of consumables.<\/li>\n<\/ul>\n

<\/span>What are the disadvantages of argon laser therapy?<\/span><\/h2>\n\n- Surgeons must have specialized training before they can do laser therapy, and strict safety precautions must be followed.<\/li>\n
- Laser therapy is expensive and requires bulky equipment.<\/li>\n
- Additionally, the effects of laser therapy may not last long, so doctors may have to repeat the treatment for a patient to get the full benefit.<\/li>\n<\/ul>\n
<\/span>What are the side effects of argon laser treatment?<\/span><\/h2>\nSide effects of argon laser treatment may include:<\/p>\n
\n- \nLocated<\/span> herpes simplex (cold sores), bacterial<\/span> wound infection<\/span> and candida infection<\/li>\n
- Transient post-inflammatory<\/span> hyperpigmentation<\/span>\n<\/li>\n
