The VISX STAR S4 ActiveTrak Excimer Laser Eye Surgery System uses cool laser technology to correct imperfect vision by precisely removing microscopic amounts of tissue from the surface of the eye (generally 20 to 50 microns, less than the thickness of a human hair).

Who makes VISX laser?

10 following the announcement that Advanced Medical Optics (AMO), a global provider of ophthalmic surgical devices and eye care products, has acquired VISX, the leading provider of laser vision correction services, for $1.27 billion (29.0 million shares of AMO stock and $184 million in cash).

What is excimer laser used for?

They are most commonly used to correct myopia (nearsightedness) but can also be used to correct hyperopia (farsightedness) and astigmatism. The excimer laser alters the refractive state of the eye by removing tissue from the anterior cornea through a process known as photoablative decomposition.

What is the latest Lasik technology?

The FDA approved SMILE, the latest advance in laser vision surgery, in 2016. It has been shown to be as effective and safe as LASIK, and it is currently available for the treatment of myopia and myopic astigmatism.

What is the latest laser?

How do excimer lasers work?

How do excimer lasers work? The excimer laser emits a cool beam of ultraviolet light of a specific wavelength (typically 193 nanometers) to precisely remove corneal tissue. An excimer laser corrects nearsightedness by flattening the cornea; it corrects farsightedness by making the cornea steeper.

What is the basic principle of excimer laser?

Rather than burning or cutting material, the excimer laser adds enough energy to disrupt the molecular bonds of the surface tissue, which effectively disintegrates into the air in a tightly controlled manner through ablation rather than burning.

Has LASIK improved over the years?

LASIK surgery has improved by leaps and bounds over the past two decades. It was the most popular elective surgery by 2010. Approximately 95% of patients who had LASIK reported satisfaction with the results. As tools and methods continue to improve, so will the appeal and reliability of LASIK.

Who regulates lasers in the United States?

FDA Center for
FDA Center for Devices and Radiological Health. The Center for Devices and Radiological Health is part of the U.S. Food and Drug Administration. Under U.S. law (21 CFR 1040.10 and 1040.11), FDA/CDRH regulates laser equipment plus three uses: medical, surveying/alignment, and “demonstration”.
