Wavefront-guided LASIK[3] is a variation of LASIK surgery where, rather than apply a simple correction of focusing power to the cornea (as in traditional LASIK), an ophthalmologist applies a spatially varying correction, guiding the computer-controlled excimer laser with measurements from a wavefront sensor. The goal is to achieve a more optically perfect eye, though the final result still depends on the physician's success at predicting changes which occur during healing. In older patients though, scattering from microscopic particles plays a major role and may exceed any benefit from wavefront correction. Hence, patients expecting so-called "super vision" from such procedures may be disappointed. However, while unproven, surgeons claim patients are generally more satisfied with this technique than with previous methods, particularly regarding lowered incidence of "halos", the visual artifact caused by spherical aberration induced in the eye by earlier methods.

LASIK is the acronym for Laser-Assisted in Situ Keratomileusis, a type of refractive laser eye surgery performed by ophthalmologists for correcting myopia, hyperopia, and astigmatism.[1] The procedure is generally preferred to photorefractive...
Epi-LASIK is a refractive surgery technique designed to reduce a person's dependency on eyeglasses and contact lenses. Invented by Dr. Ioannis Pallikaris (Crete, Greece), the technique is basically an automatic LASEK without alcohol:

LASIK was the best thing I’ve ever done for myself. Some say that is quite expensive but its well worth it. The procedure really changed my vision into much better as I expected, and I will bring the benefits of it for the rest of my life, so price...
Although relatively uncommon, the following are some of the more frequently reported complications of Epi-LASIK [1]:
Over/undercorrection
Visual acuity fluctuation
Halos around light sources
Starbursts around light sources
Decentered ablation...
Because PRK does not involve a permanent flap in the deeper corneal layers (the LASIK procedure involves a mechanical microkeratome using a metal blade or a femtosecond laser microkeratome to create a 'flap' out of the outer cornea), the cornea's...
