Abstract
Embodiments include methods, systems, and/or devices that may be used to create aberration-corrected gradient index lenses. In some embodiments, data related to aberration measurements is received. This data is processed and an inverse map is generated to compensate for the aberration measurements. An intensity pattern corresponding to the inverse map is then projected onto a blank lens (e.g., to locally polymerize a mobile monomer) to create an exposed lens with a gradient index to correct for the aberration measurement. For example, in some embodiments, the lens may be an intraocular lens and the data can be generated by using a wavefront sensor to measure aberrations (e.g., an optical phase profile to correct defocus or astigmatism) in a patient's eye.
