A type of laser (light amplification by stimulated emission of radiation)-excited dimer made from argon-fluorine gas. A dimer is a combination molecule of two gases; in this case, argon and fluorine. It produces an invisible far ultraviolet light that vapourises the cornea with almost no damage or scarring. A - E . F - L . M - P . R - V

Is a high energy, cold laser that is used to reshape corneal tissue in LVC by emitting a pulsating beam of ultraviolet light that removes corneal tissue to a precise depth. Our excimer laser is a small beam laser only 0.8mm wide, ensuring precise removal of tissue.
Cold beam laser for the precise removal of corneal tissue
Belonging to a family of cool beam ultraviolet rays, the Excimer is the most easily applicable to precise corneal shaping. Functions of this type of laser are controlled by computer software.
This "cool" laser utilizes ultraviolet light to modify the front area of the eye by breaking intra-molecular bonds in collagen molecules. The excimer laser is so precise that it can etch a person's name into a single strand of human hair.
A near-ultra violet laser that does not generate heat. Because they can be used to remove tissue without causing heat damage, excimer lasers have a number of medical applications.
A laser which is ultraviolet and used in lasik surgery to correct the lens.
A precisely controlled laser that uses computer programming and cool ultraviolet light to perform refractive surgeries such as LASIK and PRK. The Casey Vision Correction Center performs procedures with both Summit Apex Plus excimer laser and the newer Nidek EC-5000 laser.
The ultraviolet laser used to remove corneal tissue during refractive surgery
class of ultraviolet lasers that removes tissue accurately without heating it. In refractive corneal surgery, controlled by computer to make precise preprogrammed shavings of eye tissue to produce a given optical correction. Used for photorefractive keratectomy (PRK); combined with automated lamellar keratoplasty (ALK) to produce LASIK.
A medical device to emit laser energy created by a mixture of argonfluoride gases. Used in photorefractive kerotectomy (PRK) and LASIK (laser- assisted intrastromal keratoplasty) to reshape corneal curvature by ablating, or burning off, tissue from the center of the cornea. The excimer laser is not used to treat patients with keratoconus.
A type of laser used to remove the outer layer of the cornea in photorefractive keratectomy (PRK).
is an ultraviolet laser used in refractive surgery to remove corneal tissue.
An argon-fluoride laser that emits ultra-violet light at a wave length of 193 nm. This "cool" laser uses ultra-violet light to alter the front surface of the eye by breaking intra molecular bonds in collagen molecules. This laser was originally developed for use in the microprocessor industry and later found its application in vision correction.
An instrument that uses shorter wave ( ultraviolet) light to vaporize and remove tissue from the eye's surface during vision correction procedures.
A type of laser used in laser vision correction that removes tissue from the cornea.
A "cold" laser used in refractive surgery to remove corneal tissue.
Laser energy produced by several rare gas-halide mixtures. The term excimer comes from the concept of an energized molecule with two identical components or excited dimer (contracted to one word exci-mer). In PRK the term has for practical purposes become synonomous with the argon-fluoride (ArF) gas version. The wave length of an ArF excimer laser is in the far ultraviolet range at 193nm.
A type of laser used in PRK or LASIK that removes tissue from the cornea.
An excimer (a contraction of EXCIted dimMER) laser is a gas laser used as high-output, high-efficiency pulsed laser light source in the visible short-wavelength, ultraviolet or deep ultraviolet spectra. Closed-shell atoms of inert gases, which do not form stable molecules in the base state, are excited by discharge to form strong bonds with other stable-state atoms, creating a diatomic molecule. Excimer lasers utilize the transition between this excimer state and the ground state for laser oscillation.
An ultraviolet-based laser that generates energy pulses that when directed by computer control, is used to reshape the surface of the cornea. It was originally designed for etching computer chips. It was approved by the FDA for use in the correction of nearsightedness in 1995.
The term excimer comes from the combination of excited and dimer. The excimer laser was developed in the late seventies and has output in the ultraviolet and near ultraviolet region. In an excimer laser a noble gas such as krypton, Kr, or xenon, Xe, is excited in the presence of a halogen such as fluorine, F, or chlorine, Cl, and neon, Ne, or helium, He, in a resonant cavity. A high voltage pulse dissociates electrons from the noble gas molecules creating a plasma. In the excited state, noble gas atoms combine with the halogen atoms forming a metastable compound such as KrF or ArF with a lifetime of several nanoseconds. When the electrons in the outer shell of the excited compound are stimulated to a lower energy level, ultraviolet light is emitted and the metastable compound disassociates in a few femtoseconds into the original elements.
Used in PRK (photorefractive kerototomy) and LASIK (laser-assisted intrastromal keratoplasty) to reshape corneal curvature by ablating, or burning off, eye tissue.
Laser energy produced by several rare gas mixtures. In PRK or LASIK, the term refers to the argon-fluoride (ArF) gas. It is an ultraviolet wavelength.
An excimer laser is a form of ultraviolet chemical laser which is commonly used in eye surgery and semiconductor manufacturing.
