Laser Augmented In-situ Keratomileusis (LASIK)
 ASIK is performed in a manner similar to ALK (KMIS)
except for the second pass of the microkeratome.
In LASIK, currently, an excimer laser is used to remove
the second disk of tissue. This method is supposed
to produce a more even cut and consequently better
results. Whether this is true still remains to be seen. Early
reports are encouraging but all reports of new techniques
generally are. But there have been some disturbing reports of induced irregular astigmatism following LASIK which have resulted in loss of best corrected visual acuity (BCVA). There is no question that glare is increased. In point of fact, the incidence of lasting post-LASIK glare seems higher than that following RK. Even in a perfectly performed and well-centered LASIK, some loss of contrast sensitivity may remain though not nearly as bad as that seen following Lasers in Refractive Surgery and my comments following this section before deciding on LASIK for yourself or your family (see Not all refractive errors are 'nails').
