This describes the use of wavefront measurement and adaptive optics to correct all the aberrations of the human eye.ApplicationsWavefront measurement of all the aberrations in the human eye can make possible correction of vision which goes beyond conventional spectacles and contact lenses. This correction of higher order aberrations can be applied in custom laser refractive surgery, intraocular lenses and improved custom c contact lenses.In addition, the measurement and correction of aberrations improves the quality of retinal imaging, used to diagnose diseases in the back of the eye, in such instruments as scanning laser opthtalmoscopes and optical coherence tomography (OCT).AdvantagesWith the complete wavefront information on the aberrations, it is possible to correct aberrations beyond defocus and astigmatism, allowing improved vision. Removing the aberrations of the eye also improves imaging of the inside of the eye to obtain high resolution images that otherwise are impossible.
