Who Is Not a Candidate for Wavefront?
Even though wavefront is an advancement in LASIK, it is not for everyone. Because wavefront involves the removal of more corneal tissue than conventional LASIK, individuals with thin corneas may not be candidates. If you have small pupils you may not be a candidate because the wavefront measurements require a minimum pupil size for accuracy. For technical reasons, in some people the traditional measurements are more accurate than the wavefront measurements. Your surgeon will recommend the method of measurement that gives you the best chance of excellent vision.
The risks of wavefront-guided LASIK are the same as the risks of conventional LASIK. However, it is important to note that wavefront-guided LASIK may actually prevent some of the side effects that occur more often with conventional LASIK. Some patients who undergo conventional LASIK have problems with glare and halos around lights at night or in dim lighting. These side effects usually occur because conventional LASIK can increase some higher-order aberrations. Because wavefront-guided LASIK is designed to correct these higher-order aberrations, such side effects are less likely to occur.
