The aim of this study is to analyze the results of PresbyLASIK performed using the
wavefront-optimized LASIK for the treatment of presbyopia on low hyperopic and low myopic
patients with astigmatism. Visual performance will be assessed using clinical outcome
measures of the following: refraction, near, intermediate and distance visual acuity,
stereoacuity and contrast sensitivity. Questionnaires will also be used to evaluate how the
patient's vision is before and after surgery.
