Who is eligible for laser eye surgery?
The progress in medicine and especially in the area of care and
"comfort" that can improve the quality of life, such as the correction
of sight by use of a Laser has become far more common over the last ten
to fifteen years. Nearly all optical defects: nearsightedness,
farsightedness, astigmatism, and so on can now be corrected.
MYOPIA
If your eye is too deep or the cornea and the lens have an excessive
refractive power; light rays are focused in front of the retina. This
means that the vision is blurred by a considerable amount.
ASTIGMATISM
If the cornea is more curved in one direction than the other, (like a
rugby ball), the elements that make up the images are focused at
different distances from the retina, making the images blurred near and
far. Astigmatism can be combined with myopia or hyperopia, or even both.
HYPERMETROPIA
If your eye is too short or the cornea and the lens do not have
enough refractive power; light rays are focused behind the retina, so
that you see much less clearly objects when they are closer.
PRESBYOPIA
It typically begins around age 40, this defect is corrected by
glasses or bifocals or progressive glasses wearing two different pairs
of glasses.
The refractive
To allow you to see clearly, the cornea and the lens must refract,
i.e. diverting light rays (hence the term "refraction") and focus on the
retina, a layer of cells sensitive to light lining the back of the eye.
The light is converted into electrical impulses that are transmitted
through optic nerve to the brain which makes images. If the light rays
are not focused properly on the retina, the image that you receive will
be blurred; this defect is called a flaw refraction.
You would need glasses, contact lenses or refractive surgery to correct
defects or decrease of refraction by changing the path of light rays in
order to focus on, or closer to the retina.
To be eligible to have any of the above problems resolved with the use
of different laser surgery methods. Several criteria must be met, age
must be 18 years or more, vision quality must be stable, the eye must,
in addition to the default view, be healthy, the indication must be
reasonable, carefully considered and discussed with the ophthalmologist,
whether aesthetic, functional, professional sports, even purely medical,
the general state of health is also important, we must point out to your
ophthalmologist any illness or treatment with medication |
