Tips and Tricks about Eye surgery
Eye surgery is one of the most efficient methods of vision
correction. The patients can choose between three methods and I
am going to present you the advantages and disadvantages of all
these types of eye surgeries: lasik eye surgery, implants and
intacs.
Lasik Eye Surgery Laser-Assisted In Situ Keratomileusis, or the
Lasik eye surgery is the most well known surgical way of
correcting vision. The lasik eye surgery permanently corrects
vision by removing a thin layer of the cornea. The lasik eye
surgery is indicated for the patients with moderate to high
degrees of myopia, low to moderate degrees of hyperopia and
astigmatism associated with myopia, and who have thick corneas.
The lasik eye surgery involves a few risks the have to be taken
into consideration. There is a small chance of losing vision,
which usually occurs if patients had a pre-existing condition
which should have averted the eye surgery in the first place,
such as cataracts, diabetes, pregnancy, glaucoma, lupus or
arthritis. Also, the lasik eye surgery is not recommended for
persons with large pupils. Dry eye syndrome will be worsen by
the lasik eye surgery. There were signalized a few side effects
of the lasik eye surgery. There were patients who complained
that they see "ghosts" images, have confused vision, bad night
vision and reduced contrasts. The improvements in the lasik eye
surgery have decreased the rate of post-operative complaints at
less than 1%. Anyway, if any problems appear after the lasik eye
surgery , they can frequently be resolved by a re treatment.
Intacs
Intacs are not as well known as lasik eye surgery but they can
correct vision in persons with mild to moderate myopia without
involving the risk of permanent eye damage. Intacs are
semi-circular disks implanted in the cornea which stretch it to
assume a flatter shape. If the patient who chooses this kind of
eye surgery has an unexpected over- or under-correction, the
implant can be removed and replaced by a proper one. This type
of eye surgery is inappropriate for grave myopia and more than
minor astigmatism(1.00 diopters).
Implants Intraocular lens implants (IOL) are a new type of eye
surgery approved by the FDA in 2004, which can correct moderate
to severe myopia, and are appropriate only for patients who have
2.5 diopters or less of astigmatism. Through this type of eye
surgery an artificial lens is inserted in front of the natural
lens. The main secondary effect of this eye surgery is the
constant loss of endothelial cells of 1.8 % a year in the
corneas of patients who received the implants. Some severe
complications of this type of eye surgery were: retinal
detachment (0.6%), cataract development (0.6%), and corneal
swelling (0.4%). Even if the implant can be removed, vision may
not always return to what it was prior getting the lens.
