LASIK and other forms of laser refractive surgery, such as PRK and LASEK, all use a highly specialized excimer laser to reshape the cornea and correct refractive errors including myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. Excimer lasers have revolutionized the field of laser eye surgery, and over the decades have greatly increased in safety, efficacy and predictability of corneal refractive surgery outcomes. LASIK Excimer lasers have the ability to remove, or "ablate," microscopic amounts of tissue from the cornea's underlying stromal layer, with a very high degree of accuracy, and without damaging the surrounding corneal tissue. Several FDA-approved excimer lasers are on the market, but one is not necessarily "better" than another. A few of these lasers include the Alcon EX500, AMO VISX S4 IR, Bausch & Lomb Technolas TENEO 317, & Zeiss MEL 80 Excimer Laser, just to name a few. The most suitable excimer laser for a practice will depend on th Read More

The development of the LASIK Excimer Laser is the key element that has made laser eye surgery possible. Created by a major technology company, Excimer Lasers, derived from the terms excited and dimmers, use reactive gases, such as chlorine and fluorine, mixed with inert gases such as argon, krypton or xenon, commonly referred to as “premix”. When these gases are electrically stimulated, a pseudo molecule is produced that, when lased, produces light in the ultraviolet range. Read More

When these gases are electrically stimulated, a pseudo molecule is produced that, when lased, produces light in the ultraviolet range. The LASIK Excimer Laser is a cool laser, which means that it does not heat up the surrounding air or surfaces. Instead, a very tightly-focused beam of ultraviolet light is emitted. The ultraviolet light is absorbed by the upper layer of the surface that it contacts. The sheer amount of ultraviolet light is too much for the cornea of the eye to absorb, resulting in the breakdown of the molecular bonds of the material, thus reshaping the surface of the cornea.
