Why would surface ablation result in more optimal vision?
The last disadvantage of flap associated procedures stems from the induction of higher order aberrations, which the flap itself induces. These aberrations have been shown to slightly limit optimal vision correction. Our practice would like to introduce you to the most advanced form of laser vision correction. It is called Epi-LASIK. This is actually a misnomer because when people think of LASIK they think of the procedure where a flap is created, reflected off the cornea and then restored into position following a laser treatment. Epi-LASIK does not involve the creation of a permanent flap. Instead a special instrument is used to mechanically separate the surface skin from the central cornea. This skin is then discarded and the laser treatment is applied to the corneal tissue. The skin heals in 3-5 days and a contact lens is worn during this time to increase comfort and speed healing.
