简要总结
The purpose of this study is to compare visual acuity, safety, predictability, corneal biomechanics, dry eyes, and nerve-morphology after all femtosecond laser refractive lenticule extraction. Approximately 30 to 40 patients with moderate to high myopia will randomly (after ocular dominance) receive ReLEx flex in one eye, and ReLEx smile in the other.
