This invention comprises a combined optical wavefront aberrometer and topographer system that is used in conjunction with a contact lens that has a plurality of fiducial marks disposed on the lens. The fiducial marks are located radially inside of the undilated pupil's diameter. The optical imaging capacity of the aberrometer is used to measure and monitor any misalignments of the contact lens's position (XY decentration) and/or rotation. Image analysis algorithms are used to track the positions of the fiducial marks, and, hence, the amount of geometric misalignment of the contact lens can be calculated. The fiducial marks can comprise micro ink spots, or depressions in the surface of the contact lens (e.g., divots, dimples, pits), or other small surface features, including raised bumps, which can help to stabilize motions of the contact lens on the eye.

Methods and system to identify position, rotation, and tilt of a contact lens on an eye

A method and system for correcting vision in an eye that uses a wavefront-customized phakic or pseudophakic Intraocular Lens (IOL), the method comprising: (1) measuring wavefront aberrations of the eye; (2) designing a wavefront-customized correction profile for an IOL; (3) creating a customized IOL with the customized correction profile; and (4) implanting the customized IOL in the eye, without having to remove the natural lens. Alternatively, an uncorrected IOL is implanted first, followed by scanning a femtosecond laser spot across the implanted IOL to locally change the Index of Refraction of the IOL material and create an in-situ customized IOL.

System and methods for customizing an intraocular lens using a wavefront aberrometer

This invention relates to methods and devices for designing customized contact lenses, by initially making dynamic wavefront sensor measurements through a trial contact lens that is fitted on an eye, and then calculating a WaveFront Guided (WFG) correction to be applied to the trial contact lens that reduces the RMS level of aberrations as much as practically possible. The output of the wavefront correction program is a customized lathe file that the manufacturer can use to make customized contact lenses on a lathe. The method works best for soft contact lenses and scleral lenses.
