Types Of Eye Procedures For Nearsightedness
Among the many procedures one can undergo for vision correction,
Lasik is perhaps the most widely used. Lasik, or Laser-Assisted
In Situ Keratomileusis, is a corrective surgical procedure that
changes the shape of the cornea (the transparent cover at the front
of the eye through which light enters) in order to 'repair' vision
problems. Essentially, it modifies the focusing power of the eye,
which is just what eye glasses and contact lenses do, but, of course,
it is permanent. Although suitable for sufferers of astigmatism
and hyperopia (far-sightedness), Lasik is but one of the many types
of eye procedures for nearsightedness
as well.
Other eye procedures for myopia include: Thermokeratoplasty, the
process by which heat (a laser, usually) is used to alter the cornea's
shape; orthokeratology, which makes use of specialized contact lenses
that are capable of reshaping the cornea. Similarly, nearsighted
eye operations can also be performed using RK (Radial Keratotomy)
and PRK (Photorefractive Keratectomy) to much the same effect as
Lasik. In fact, PRK is the predecessor to Lasik technology. Essentially,
all these procedures differ not so much in the technology used,
but in the manner in which the operation to correct nearsight problems
is carried out.
In Lasik, for example, a flap is cut in the cornea and folded back
in order for the laser to directly hit the stroma. PRK, on the other
hand, sculpts the surface of the eye rather than requiring a cut
to be in the cornea itself. There are advantages and disadvantages
to each type of eye surgery and it's best to discuss these with
a licensed practitioner. Besides, your eyes will need to be evaluated
in order to determine if you are a suitable candidate for such an
eye operation to correct nearsightedness.
If you consider yourself to be just a little too squeamish to undergo
surgery (c'mon, admit it, it is pretty darn scary to have something
boring away so close to your brain) then perhaps you've already
considered ophthalmic devices such as eye glasses or contact lenses.
If that's the case, make sure to give the links on the right-hand
side of this article a once over. There you'll find a surprisingly
massive collection of useful contact
lens products, and none with lasers that will go anywhere near
your eyes... probably.
