Lasik
Surgery
LASIK has
quickly become the procedure of choice for most
patients because they recover quickly and have
fewer side effects and complications than with
other methods of vision correction. In fact,
most LASIK patients notice a significant
improvement in their vision soon after surgery.
LASIK removes tissue within the cornea to treat
low to high levels of nearsightedness,
farsightedness and astigmatism.
LASIK combines the precision of the Excimer
laser with the creation of a flap in the cornea.
First, no removal of the corneal surface tissue
is necessary and therefore, postoperative pain
is virtually eliminated. Second, postoperative
visual acuity is restored within a few days
rather than weeks. Finally, there is less
corneal scarring in the long-term, less change
due to healing (regression) and thus greater
stability of the correction.
LASIK improves the uncorrected vision for
distance - one's visual capacity while not
wearing corrective lenses - in most patients who
have the procedure. Nearly all patients can
expect to achieve 20/40 vision, which most
states consider good enough to drive without
having to wear contacts or glasses, and many can
expect to achieve 20/20 vision or better.
However, there are no guarantees that you will
have perfect vision. People who are most
satisfied with the results of laser correction
clearly understand the potential risks and
complications and possess realistic expectations
of what their vision will be like after surgery.
