What is Custom
(Wavefront) Refractive Surgery?
Custom or Wavefront technology uses a special analyzer
to produce a detailed map of light rays as they travel
through the eye creating a map of the optical system
similar to a “fingerprint”. This is much
more precise than standard measurements and can be directly
programmed into the excimer laser customizing the surgery
for each eye’s unique vision correction needs.
Benefits include: higher likelihood of achieving better
quality vision, lesser likelihood of having night vision
difficulties i.e. glare, haloes, starbursts, and potential
for improvement in vision over that possible with glasses
or contact lenses
What is PRK?
PRK (Photorefractive keratectomy) also referred to
as surface ablation uses the excimer laser to reshape
the cornea after the epithelial (surface) cells are
removed . Like LASIK, PRK can correct nearsightedness,
farsightedness, and astigmatism. No flap is created
during PRK therefore the reshaping of the cornea takes
place at a more superficial level. In some patients,
due to individual anatomic variations, PRK may be the
procedure of choice for safety reasons. PRK patients
typically have a longer recovery time and may experience
more post-operative discomfort.
Am I A Candidate?
A detailed exam will determine whether you make a good
candidate for laser vision correction. Generally, candidates
must:
- Be at least 18 years of age
- Be in good general health
- Have no conditions that affect the eyes
- Have a stable prescription for at least one year
Are these Procedures FDA Approved?
Yes, LASIK and PRK and Custom LASIK/PRK have been approved
by the FDA as safe and effective.
