What is LASIK?

The eye and vision errors

The cornea is a part of the eye that helps focus light to create
an image on the retina. It works in much the same way that the lens of
a camera focuses light to create an image on film. The bending and
focusing of light is also known as refraction. Usually the shape of the
cornea and the eye are not perfect and the image on the retina is
out-of-focus (blurred) or distorted. These imperfections in the
focusing power of the eye are called refractive errors. There are three
primary types of refractive errors: myopia, hyperopia and astigmatism.
Persons with myopia, or nearsightedness, have more difficulty seeing
distant objects as clearly as near objects. Persons with hyperopia, or
farsightedness, have more difficulty seeing near objects as clearly as
distant objects. Astigmatism is a distortion of the image on the retina
caused by irregularities in the cornea or lens of the eye. Combinations
of myopia and astigmatism or hyperopia and astigmatism are common.
Glasses or contact lenses are designed to compensate for the eye's
imperfections. Surgical procedures aimed at improving the focusing
power of the eye are called refractive surgery. In LASIK surgery,
precise and controlled removal of corneal tissue by a special laser
reshapes the cornea changing its focusing power.

WILL MY PROCEDURE BE PAINFUL?

Patients experience virtually no discomfort during the LASIK Vision
Correction procedure. Eye drop anesthesia is used to numb the eye prior
to the procedure, so no injections are necessary. Immediately after
treatment, some patients have reported minor discomfort, like having an
eyelash or a dry contact lens in their eye.

Dr. Boothe
Monovision- When one eye is deliberately corrected for distance vision and the other for close vision.

Dr. William Boothe : Farsightedness, Hyperopia:

Farsighted people can usually see things that are far away better
than things that are close. A farsighted prescription will have a
positive number under the sphere column.
