Summary

The purpose of this study is to conduct a prospective assessment of small target contrast sensitivity and disability glare in refractive surgery. Study subjects will undergo the treatment of their choice (PRK or LASIK) and will be evaluated before and after treatment. Evaluations will include best corrected visual acuity, uncorrected visual acuity, psychometric questionnaire, pupil size, biomicroscopic examination, manifest refraction, wavefront measurements, low contrast acuity, and contrast sensitivity at normal and at low luminance with and without disability glare.
