Trial ID: NCT01138189


The purpose of the study is to compare the results of LASIK surgery when using wavefront-guided excimer laser treatment compared to wavefront optimized excimer laser treatment in patients with nearsightedness with and without astigmatism

Inclusion Criteria:

   - Subjects age 21 and older with healthy eyes.

   - Nearsightedness between -7.50 diopters and -7.00 diopters with or without astigmatism
   of up to 3.50 diopters.

Exclusion Criteria:

   - Subjects under the age of 21.

   - Patients with excessively thin corneas.

   - Patients with topographic evidence of keratoconus.

   - Patients with autoimmune diseases.

   - Patients who are pregnant or nursing.

   - Patients must have similar levels of nearsightedness in each eye. They can not be more
   than 3.0 diopter of difference between eyes.

   - Patients must have similar levels of astigmatism in each eye. They can not have more
   than 4.0 diopters of difference in nearsightedness or astigmatism between their two
