Lasik (laser assisted in situ keratomileusis) is now a common eye surgery in which a laser is used to remove a thin layer of cornea, correcting vision in the eye so glasses or contacts do not need to be worn. typically, a laser known as an excimer laser is used, with a wavelength of 193 nm, which has been shown to produce high-quality incisions in the delicate tissue of the eye. (a) in what section of the electromagnetic spectrum does a wavelength of 193 nm place this laser? gamma x-ray ultraviolet visible infrared microwave radio wave long wave correct: your answer is correct. (b) if such a laser has a power of 8.00 mw, and is turned on for pulses lasting 40.0 ns each, how much energy is delivered by the laser to the eye in each pulse

LASIK, or "laser-assisted in situ keratomileusis," is the most commonly performed laser eye surgery to treat myopia (nearsightedness), hyperopia (farsightedness) and astigmatism.

Like other types of refractive surgery

, the LASIK procedure reshapes the cornea to enable light entering the eye to be properly focused onto the retina for clearer vision.

In most cases, laser eye surgery is pain-free and completed within 15 minutes for both eyes. The results — improved vision without eyeglasses or contact lenses — can usually be seen in as little as 24 hours.

If you're not a good LASIK candidate, a number of other vision correction surgeries are available, such as PRK and LASEK laser eye surgery and phakic IOL surgery. Your eye doctor will determine if one of these procedures is suitable for your condition and, if so, which technique is best.
