In the surgical procedure LASIK, the shape of the cornea may be flattened. This will result in which of the following?

A
Decreased refraction of light by the cornea
B
A decreased amount of light entering through the cornea
C
Conversion of the cornea from a "stationary" to an "adjustable" form of refraction
D
Maintenance of the lens in a more flattened state
High-Yield Explanation
Decreased refraction of light by the cornea * LASIK has largely replaced radial, or refractive, keratotomy. Both methods can be used to decrease the refraction of light by the cornea. * LASIK alters corneal (not lens) anatomy to create a new shape that is more flattened in the center and higher at the periphery of the cornea. This occurs because intraocular pressure will cause a reshaping of the cornea due to induced weakness produced by the laser removal of tissue. * The purpose of the procedure is to reduce myopia to eliminate the need for corrective lenses. * The reduction in curvature of the central poion of the cornea results in decreased refractive power of the cornea. * The removal of tissue and the degree of correction required is estimated by computer simulations.
