Summary

This trial is comparing the outcomes of two different types of LASIK surgery in patients with nearsightedness with and without astigmatism.

Who is the study for?
This trial is for adults over 21 with healthy eyes who have nearsightedness ranging from very mild to severe (-0.25 to -11.00 diopters), with or without astigmatism up to 5.00 diopters. It's not suitable for those with certain eye conditions like keratoconus, pregnant or nursing individuals, people under 21, those with thin corneas, significant differences in vision between eyes, or autoimmune diseases.
What is being tested?
The study is examining the effectiveness of two types of LASIK surgery: one using a high definition wavefront-guided laser and the other using a wavefront-optimized laser. The goal is to see which method provides better results for correcting nearsightedness and astigmatism.
What are the potential side effects?
LASIK surgery may cause dry eyes, glare, halos around lights at night-time, fluctuating vision during recovery period and rarely more serious complications such as loss of vision.
