Both PRK and LASIK are effective for vision correction; however, doctors are increasingly leaning towards LASIK because of the faster visual recovery rate and fewer post-operative visits. These are also much more preferable to the patient.

Currently, there are two forms of surgery that can correct these errors: Photorefractive keratectomy (PRK) and laser in situ keratomileusis (LASIK).

PRK uses a laser for vision correction to reshape the surface of the cornea by emitting pulses of light.

With LASIK, a thin flap is made across the surface of the eye using a microkeratome. This highly sophisticated device allows the laser to be applied to the deeper layers of the cornea underneath the flap, reshaping the underlying tissue. The flap is then laid back in place, usually requiring no sutures. The patient feels nothing during the process.

Both procedures are effective in the correction of myopia and astigmatism. The chart below illustrates the differences:

Zyoptix personalized laser vision correction can be performed using PRK or LASIK. The initial testing for Zyoptix takes longer, however, the actual procedure is basically the same from the patient's perspective.

Your physician will recommend the best surgical solution for your vision correction.
