L A S I K,
"laser assisted in-situ keratomileusis
is a procedure  that  uses cool laser energy  to reshape the cornea.
LASIK candidates  should be in good general health & present with
a  normal  ocular health evaluation. The surgery, takes about five to
ten minutes, with the laser application taking less than two minutes

The cornea is a part of  the eye that helps focus light to create an image on the retina. It works in much
the  same  way that the  lens of  a camera  focuses  light to create  an image on film.  The  bending and
focusing of light is also known as refraction. Usually the shape of the cornea and the eye are not perfect
and the image on the retina is out-of-focus (blurred) or distorted. 

These imperfections in the focusing power of the eye are called refractive errors. There are three primary
types  of  refractive  errors:  They are myopia,  hyperopia  and  astigmatism.  Persons  with  myopia,  or
nearsightedness,  have  more difficulty seeing  distant  objects as clearly as near objects.  Persons with
hyperopia, or  farsightedness,  have  more difficulty  seeing  near objects  as clearly  as distant  objects.
Astigmatism  is a distortion of the image  on the retina  caused by irregularities in  the cornea or lens of
the  eye.   Combinations  of  myopia  and  astigmatism  or  hyperopia  and  astigmatism  are  common. 

In  LASIK  surgery,  precise and controlled  removal of corneal  tissue by a special  laser, reshapes  the
cornea changing its focusing power.  LASIK  is a procedure that  permanently changes the shape of the
cornea,  the  clear  covering  of  the  front of  the eye, by  using  an  excimer  laser.  A  knife,  called  a
microkeratome,  is used to  cut a  flap in the cornea.  A hinge is left  at one end of this flap.  The flap is
folded back revealing the stroma,  the middle section of the cornea.  Pulses from a computer-controlled
laser vaporize a portion of the stroma and the flap is replaced.

Lasik will not rid the world of glasses but will reduce the need for them. For a general idea of what your vision should be after Lasik refer to the chart. 

Remember that many factors such as age, pupil size, and astigmatism have an effect on your final vision. This chart is based on a clinical study of 612 patients.

As with any surgery there are certain risks involved and no guarantees of the exact outcome. We recommend that you
educate yourself on the pros and cons of Lasik before you make any decisions on surgery.

LASIK Success Rate*
Case Intial Rx 20/40 20/30 20/20
Mild -0.50 -3.00 D 99% 99% 84%

Moderate -3.10 -6.00 D 99% 97% 71%

Severe -6.10 -9.00 D 99% 95% 60%

Extreme -9.10 -30.00 D 75% 58% 30%

* Results are based on a clinical study of patients
treated with one or more LASIK procedures for myopia
Many of our patients are interested in LASIK to reduce their dependence on corrective lenses, or  eyeglasses.  If  you are  a  good  candidate, one  of   these   procedures  can   be  for   you.
