Lasik laser eye correction is a form of refractive surgery. The word lasik is the short term for "Laser assisted in situ kerotomileusis".

Lasik correction is a surgery that changes the shape of the cornea to correct hyperopia, myopia and astigmatism eliminating the need for glasses and contact lenses. People with myopia or near sightedness see things clearer when they are close as opposed to far objects. People with hyperopia or far sightedness have trouble seeing near objects as clearly as far objects. Astigmatism is when the image in the retina is distorted, this is caused by an abnormal shape of the cornea.

Lasik eye surgeons correct the refractive error by using a knife called a microkeratome to cut a thin c shaped flap in the cornea. The flap is then folded back exposing the stroma which is the center of the cornea. Pulse from an excimer laser uses an ultra violet beam to remove part of the stroma giving a normal shape to the cornea. The flap is then replaced.

The cornea is the thin layer of skin in the front of the eye. Its job is to help focus light to create an image on the retina. This is known as refraction. When the cornea becomes out of shape it creates an out of focus, blurred or distorted image called refractive errors.

Projection for Almost Doubling of Health Care Spending, to Almost $4.1 Trillion

Health care will account for nearly 20 cents of every dollar spent in the U.S. in 2016, government experts predict.

If so, America's health care tab will be nearly twice as large as in 2006.

U.S. health care spending weighed in at $2.1 trillion last year. By 2016, the figure is projected to jump to $4.1 trillion, according to a government report published in Health Affairs.

Researchers included John Poisal, deputy director of the National Health Statistics Group, which is part of the Office of the Actuary in the Centers for Medicare and Medicaid Services.

The report predicts the annual growth rate for prescription drug spending will soar from 7.4% in 2007 to nearly 10% in 2016.

The growth in health care spending on hospitals, expected to be about 7% starting this year, is predicted to keep that pace through 2016, according to the report.
