Customized correction of wavefront aberrations in abnormal human eyes by using a phase plate and a customized contact lens

Wavefront aberrations in human eyes were measured with a Shack-Hartmann wavefront sensor. Based on the measured wavefront aberrations, customized optics, such as phase plates and a customized contact lens, were designed and fabricated to compensate for higher-order wavefront aberrations in human eyes. The fabricated customized optics could successfully correct higherorder aberrations in human eyes and improve retinal image quality, and compensating for such aberrations with customized optics might be a promising technique to improve human vision.
