Just as when LASIK was first approved in 1995, the FDA approval
of Wavefront-guided CustomVue LASIK was initially for nearsighted
individuals. Nearsighted individuals with up to -6 diopters
or refractive error and/or astigmatism between 0 and 3 diopters
may qualify for wavefront.
Now, farsighted individuals and those with mixed astigmatism
may qualify for CustomVue wavefront, too.
Wavefront candidacy is still guided by physician review
and interpretation of one' higher order aberration. Prevailing
wisdom is patients with higher order aberrations that make
up 20 percent of the total aberrations of the eye make better
custom Wavefront LASIK patients.
CustomVue wavefront patients must be at least 21 years
of age or older and have a stable manifest refraction (no
more than 0.5 diopter change for the previous year).
It is not recommended for patients with collagen vascular,
auto-immune or immunodeficiency diseases; women who are
pregnant or nursing; signs of keratoconus or abnormal corneal
topography or are taking Accutane or Cordarone medications.
Other conditions that may affect candidacy include diabetes,
history of Herpes simplex or Herpes zoster keratitis; significant
dry eye that is unresponsive to treatment, and severe allergies.
