Lasik Eye Surgery Procedure - Extremely Precise Vision Correction
The most commonly used refractive
surgery procedure is the lasik eye surgery procedure and this is a very popular
form of surgery that has the advantage of being less painful and resulting in a
20/20 vision in most cases, usually on the very next day.
The basic lasik surgery procedure involves an
instrument which is known as a microkeratome which is used in the surgery to
create a thin and round flap in the cornea. The surgeon will take the flap and
fold it back so that it is not in the way and then takes away some corneal
tissue that is underneath with the help of an excimer laser which uses cool
ultraviolet light beams to exactly remove very small bits of tissue from the
cornea in order to reform it.
Once the cornea is reformed into the correct shape it
will work in an improved manner and focuses light into the eye as also onto the
retina thereby getting the person to see clearly which will be better than what
it was before the lasik eye procedure. Afterwards, the flap is replaced back in
place and covers the area where the corneal tissue had been removed.
Corrects Nearsightedness, Farsightedness as well as
Astigmatism
Lasik surgery procedure is helpful for nearsighted as
well as farsighted people. In the case of nearsightedness the aim is to flatten
the extra-steep cornea and with farsightedness, a steeper cornea is required.
Excimer lasers are also used to rectify astigmatism through smoothening of the
irregular cornea and getting it into a more normal shape and the lasik eye
procedure will help to achieve this.
There are certain steps to follow before getting your
lasik eye procedure performed and these include choosing a good surgeon, finding
out whether you are the right person for this type of surgery as well as finding
out whether you have any dry eye diseases which need to be treated and cleared
prior to the lasik eye procedure.
There are different types of lasik eye procedures such
as blade versus bladeless and also custom lasik or wavefront lasik procedures.
The wavefront-guided lasik eye surgery procedure makes use of 3-dimensional
measurements that figures out how the eye processes images and this is helpful
for guiding the laser in reshaping the front portion of the eye that is called
the cornea. The wavefront measurement of the lasik eye surgery procedure is
extremely useful in extreme and precise individualized vision correction.
