| Laser Vision
Correction is now in its second decade of helping patients
reduce or eliminate their dependency on glasses and contact
lenses. Heavy patient demand for laser vision correction has
inspired surgeons and laser manufacturers to make tremendous
advancements in both Excimer laser technology and surgical
techniques.
When laser vision correction was first performed in 1988,
only low to moderate nearsighted patients without astigmatism
could be treated. Today, with third generation Excimer lasers,
very low to moderately high degrees of nearsightedness, farsightedness
and astigmatism can be effectively treated.
LASIK
One of the most popular ways to correct vision is with a procedure
called LASIK (laser in-situ keratomileusis), which uses a
laser to change the curvature of the cornea (outer window
of the eye). LASIK has quickly become the procedure of choice
for most patients because they recover quicker 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 moderate levels of nearsightedness, farsightedness and
astigmatism.
LASEK
LASEK is a relatively new laser vision procedure that combines
elements of PRK and LASIK, and may offer some advantages over
both. Instead of removing the epithelium (the thin layer of
protective skin that covers the cornea) like in PRK, a flap
of surface epithelium is loosened with a diluted alcohol solution
and moved aside. The surface under the epithelium is then
treated with the laser and the epithelial flap is returned
to its original position. Using the epithelium flap as a natural
protective bandage with LASEK, as opposed to completely removing
the epithelium as with PRK, may improve healing and the incidence
of postoperative haze.
LASEK removes tissue within the cornea to treat low to high
levels of nearsightedness, farsightedness and astigmatism.
Wavefront Guided LASIK/LASEK
Custom laser treatment is designed specifically to treat your
unique corneal curvature and visual imperfections. Wavefront
is a mapping system that reveals the way your entire optical
system processes light. Like your DNA or fingerprint, your
Wavefront map is unique and individual to you and allows us
to personalise your treatment, thereby assuring the very best
possible results. This treatment can be combined with either
LASEK or LASIK
Although this site offers an
overview of a number of treatments to correct vision, the
information presented here is merely a beginning. We frequently
have patients come in to speak with us, that have already
decided which treatment they would like, only to learn that
we offer other, more suitable procedures, that will deliver
better results for them. At Birkdale Puresight, we believe
all patients should be receive a comprehensive assessment
of their vision and eye health. By doing this, we can offer
the most appropriate form of vision correction procedure to
suit you.
