A very common question that comes up is whether a certain eyeglass prescription qualifies for LASIK.
There is a simple answer based on FDA approved limits, but a more realistic answer is based on more complex set of criteria which must be applied in clinical situations.
LASIK is FDA approved for up to -14.0 diopters of myopia, up to +6.00 diopters of hyperopia, and up to 6.00 diopters of astigmatism. Most refractive surgeons treat more conservative ranges, up to -12.0 diopters of myopia and up to +3.00 diopters of hyperopia.
In addition, there are many factors which must be taken into consideration when determining if a patient is a suitable candidate for LASIK. The higher the prescription, the more corneal tissue is removed with the laser. This means that the patient’s cornea must have enough thickness to safely perform the procedure. For example, a patient with -7.00 diopters of myopia must have at thicker cornea than a patient with -2.00 diopters of myopia. Patients with high prescriptions and thin corneas are usually not good candidates, but patients with lower prescriptions may still qualify even if their cornea is thinner than average.
Another important factor to consider is the stability of eyeglass or contact prescription. If the prescription has changed more than 0.5 diopters over a year, it is advisable to wait until it stabilizes. Although LASIK enhancement is possible, it is better to wait until the prescription stabilizes.
