The purpose of the study is to compare the results of wavefront-guided LASIK surgery to topography-guided LASIK surgery in participants with nearsightedness with or without astigmatism~Three FDA-approved laser devices are being used for the study.~Two excimer lasers are being used for the study. The excimer laser is used to perform the reshaping of the cornea under a LASIK flap to correct nearsightedness, farsightedness and astigmatism. The two lasers being utilized are the Johnson and Johnson Visx CustomVue excimer laser and the Alcon Allegretto laser in the study. Both have received FDA-approval via a PMA pathway.~One femtosecond laser is being used in the study. The femtosecond laser is used to create the LASIK flap during the first part of the LASIK procedure. The Intralase iFS150 femtosecond laser is being used in the study. The femtosecond laser received FDA- approval via a 510k pathway.~All three lasers are being used according to their approved indications.
The study is comparing outcomes of wavefront-guided LASIK to topography-guided LASIK in a randomized contralateral fellow eye study in myopic participants.
