Depending
on the shape of your eye, the light rays which enter your
eye and send pictures to your brain can be focused incorrectly,
causing blurry vision.
When
your eye is shaped so that images focus in front of the retina,
you have a condition called myopia, or nearsightedness. Myopia
may be corrected by wearing glasses, contact lenses (for Orthokeratology
or otherwise), or through surgery.
Orthokeratology
is a non-surgical contact lens procedure used to reduce or
eliminate myopia (nearsightedness) and astigmatism by temporarily
changing the curvature of the cornea.
Just
as surgery to correct myopia reshapes your eye, orthokeratology
has the same effect without the risk, discomfort, or expense
of surgery.
Orthokeratology
uses specially designed contact lenses to gently change the
shape of your eye while you sleep. This lessens your myopia,
improving your vision after you remove the lenses. You will
also have excellent vision while wearing the lenses.
Orthokeratology
contact lenses for your eye are similar to orthodontics, or
braces for your teeth. Orthokeratology flattens the shape
of the cornea during wear, resulting in sharper vision while
not wearing the lenses.
The
procedure involves wearing the Nightform™ Contact Lenses
for a period of time. Usually they are worn overnight, but
sometimes during the day. After you remove the lenses, your
vision should be sharper, in most cases 20/20 or better.
This
noninvasive procedure is completely reversible, unlike with
Laser Correction. If your vision changes, your doctor can
change your Nightform™ Contact Lenses to compensate.
The
procedure is most effective on persons with low amounts of
myopia or astigmatism (-1.00 to -3.00). People with prescriptions
under -3.00 can expect to achieve 20/20 vision in a few days.
Orthokeratology
is approved by the FDA as an overnight wear procedure. While
you are sleeping, the lenses are at work. When you remove
your lenses you should be able to see without them. Most people
achieve clear, 20/20 vision, without glasses or contact lenses,
that usually last all day.
