A Comparison of Fellow Eyes Undergoing LASIK or PRK With a Wavefront-guided Excimer Laser Versus a Wavefront-optimized Excimer Laser

A Prospective Randomized Comparison of Fellow Eyes Undergoing LASIK or PRK With a Wavefront-guided Excimer Laser Versus a Wavefront-optimized Excimer Laser

Subjects with myopia, hyperopia and astigmatism are being randomized to be treated in one eye with a wavefront-guided excimer laser and their fellow eye treated with a wavefront-optimized excimer laser.

Subjects with myopia, hyperopia and astigmatism are being randomized by ocular dominance to be treated with either PRK or LASIK. One eye will be treated with a wavefront-guided excimer laser and the fellow eye will be treated with a wavefront optimized excimer laser.

Inclusion Criteria:

• Healthy subjects age 21 and older.
• Subjects with nearsightedness, farsightedness and/or astigmatism.

Exclusion Criteria:Autoimmune diseases.

• Children.
• Women pregnant or nursing.
• Ectatic corneal disease.
• Previous ocular surgery.
