Excimer laser | definition of excimer laser by Medical dictionary- excimer laser definition medical ,excimer laser: [ la´zer ] a device that transfers light of various frequencies into an extremely intense, small, and nearly nondivergent beam of monochromatic radiation in the visible or invisible spectrum, with all the waves in phase; capable of mobilizing immense heat and power when focused at close range, lasers act on tissues by ... Excimer laser - American Academy of OphthalmologySchematic representations of corneal recontouring by the excimer laser. A, Correction of myopia by flattening the central cornea. B, Correction of hyperopia by steepening the central corneal optical zone and blending the periphery. C, Correction of astigmatism by differential tissue removals 90 degrees apart. Note that in correction of myopic ...
The excimer laser is a revolutionary machine that corrects refractive errors and changes the shape of the cornea. It removes 10 to 20% of the corneal tissue and reshapes it, at the end of the surgery you will be able to see properly. Reshaping is done according to your refractive errors. For hyperopia it steepens its curvature, for myopia, it ...

Gas lasers with excited dimers (i.e., excimers) as the active medium. The most commonly used are rare gas monohalides (e.g., argon fluoride, xenon chloride). Their principal emission wavelengths are in the ultraviolet range and depend on the monohalide used (e.g., 193 nm for ArF, 308 nm for Xe Cl).

Excimer laser: A laser that emits very concentrated light in the ultraviolet (UV) region of the spectrum. Excimer lasers are used, for example, in: Ophthalmology -- to vaporize part of the surface layer of the cornea and thus reshape the cornea to correct refractive errors from myopia ( nearsightedness ), hyperopia ( farsightedness ), and ...
An excimer laser, sometimes more correctly called an exciplex laser, is a form of ultraviolet laser which is commonly used in the production of microelectronic devices, semiconductor based integrated circuits or "chips", eye surgery, and micromachining. Since 1960s excimer lasers are widely used in high-resolution photolithography machines, one ...

Excimer lasers are a family of high pressure, pulsed gas lasers that produce intense ultraviolet (UV) light with high efficiency and high peak power at several useful wavelengths. The source of the emission is a fast electrical discharge in a high pressure mixture of a rare gas and a halogen gas. The specific combination of the rare gas and the ...
Excimer laser devices emits UVB light measuring 308 nm, which is known to have therapeutic effects for certain skin conditions. This wavelength of light can eliminate the overactive immune cells that cause symptoms of eczema, for example, and can help re-pigment skin affected by vitiligo. Excimer laser treatments can also treat psoriasis when ...

Excimer laser therapy is a relatively new treatment used by medical experts to treat psoriasis, atopic dermatitis, vitiligo, and other dermatologic diseases. The therapy is mainly suggested if other conventional treatments such as oral medications, injections, or creams do not work well to improve skin conditions.

The 308 nm excimer laser is a widely used device throughout the field of dermatology for many diseases including psoriasis. Although the laser has demonstrated clinical efficacy, there is a lack of literature outlining the safety, efficacy, and patient acceptability of the excimer laser.
Invented in 1970, the Excimer Laser has served many medical purposes and continues to lead as a UV laser solution in the medical market. Excimer lasers are gas lasers that emit strong pulses of light in the ultraviolet (UV) spectrum. The name excimer comes from excited dimer. This laser has the ability to remove considerably fine layers of ...
