A world-renowned corneal surgeon, Robert D'Amico, MD performs lasik surgery in Manhattan. He also performs cataract and glaucoma surgery as well as corneal transplantation surgery in his New York City practices.
Lasik surgery in Manhattan? Patients should have some understanding of lasik surgery before having the procedure by a leading lasik surgeon in New York City.
How does LASIK vision correction work? The cornea focuses light to create an image on the retina, like the lens of a camera focuses light on the film. Refractive errors result if the cornea does not focus the image on the retina. There are three primary types of refractive errors: myopia, hyperopia and astigmatism. Persons with myopia, or near-sighted, see near objects clearly. Persons with hyperopia, or farsighted, see distant objects clearly. Astigmatism results when the shape of the eye is like a football rather than a basketball. Glasses or contact lenses compensate for the refractive errors.
Refractive surgery, including LASIK laser surgery, changes the focusing power of the eye without glasses. In LASIK laser surgery, precise and controlled removal of corneal tissue by a special laser reshapes the cornea changing its focusing power.
LASIK, Laser-Assisted In Situ Keratomileusis, permanently changes the shape of the cornea, the clear front of the eye, using an excimer laser. A knife, called a microkeratome, cuts a flap in the cornea. A hinge is left at one end of this flap. The flap is folded up. Pulses from the computer-controlled laser vaporize a portion of the cornea and the flap is replaced. After LASIK surgery, most patients find the vision greatly improved.
