So You Have Not Been Approved For Lasik Surgery – What Are
To be able to undergo Lasik Surgery, you have to have some tests
first to determine if you are qualified. Some corneal tissues will
be extracted from your eye. If your corneas are found to quite thin,
then you cannot have the surgery. If you have myopia or nearsightedness,
this surgery is also not for you. Some types of vision defects cannot
be corrected with Lasik surgery. Nevertheless, there are other treatment
methods that are available to you.
For those who do not want to undergo any kind of surgery, then
you will have to be content with wearing prescription eyeglasses
or contact lenses. Contact lenses now are better made to fit the
eyes without irritating them. They are now made of materials that
are resilient and resistant to dust and dirt buildup. Some people
may find wearing contact lenses quite cumbersome, but this is a
good alternative if you have decided that surgery is not for you.
On the other hand, if eyeglasses and contacts or surgery do not
appeal to you, one option that you can consider is having lens implants.
This is ideal if you suffer from myopia. The implant will be inserted
in a small incision in the lens. A special tool secures the lens
to the iris of the eye, and then you can forget about it. You can
have it removed if it needs to be replaced or if you decide you
do not want it anymore. Lens implants are not as irreversible as
Lasik surgery, and yet less complicated to care for and maintain
than regular contact lenses or eye glasses. This means that if some
undue side affects happen during the procedure or if they are not
that effective, then they can be just removed or replaced.
There is one more kind of procedure that you can consider; the
photorefractive keratectomy, also known as PRK. This method changes
the shape of the cornea by removing some tissues from its outer
surface. This is done with the use of an ultraviolet light beam.
The procedure will only take a few minutes and done using only the
technology without any cutting such as the procedure for lens implants
and Lasik surgery.
Then there is the laser thermal keratoplasty, called as LTK as well.
In LTK, the cornea is taken and outer parts are removed. This action
shrinks the tissue surrounding the cornea, resulting to better eyesight.
This is a temporary treatment as the tissues can grow back. However,
there are fewer drawbacks here as compared to other surgeries where
infection can ensue or cause loss of eyesight.
Another innovation in eyesight correction is orthokeratology, or
Ortho-K. This method gets the RGP contact lenses or soft contact
lenses and reshapes them to complement the form of the cornea, thus
making them less uncomfortable. The cornea will be temporarily reshaped
resulting to better vision so that you do not have to wear the lens
everyday. It will take several months to change the vision and results
are temporary. Still, it is an option one can take if he or she
does not want to undergo corrective surgery.
For those suffering from nearsightedness, there is also another
surgical procedure known as the corneal ring segments. Plastic polymer
pieces are placed on the cornea so that it can be reshaped; in this
case, flatten it so it can focus light better. This procedure is
comprable to the Ortho-K. The corneal ring placements are temporary
and results are not yet tested for effectiveness.
There are other available types of surgery which can improve vision
temporarily or permanently. Thus, if you do not not qualify for
Lasik surgery, do not despair. There are some alternatives worth
trying to improve your eyesight.
