High order aberrations in human eye can deteriorate visual acuity and contrast sensitivity. Such aberrations can not be corrected with traditional low-order (defocus and astigmatism) spectacles or contact lenses. A state-of-the-art adaptive optics vision correction system was developed using Ophthonix's Z-View diffractive wavefront sensor and a commercial miniature deformable mirror. While being measured and corrected by this system, the patient can also view a Snellen chart or a Contrast Sensitivity chart through the system in order to experience the vision benefits both in visual acuity and contrast sensitivity. Preliminary study has shown the potential that this system could be used in a doctor's office to provide patients with a subjective feel of the objective high order prescription measured on Z-View.
