Patent ID: 8632187

Claim:
A method of fitting the posterior surface of a corneal-sclera progressive multifocal rigid gas permeable lens to a post refractive surgery eye, the corneal-sclera progressive multifocal rigid gas permeable lens having sufficient diameter to cover the cornea and a portion of the sclera of an eye, the method comprising the acts of: performing and recording a pre-surgery keratometer reading of the eye; using the pre-surgical keratometer reading of the eye for determining secondary, intermediate, and peripheral curves; assessing the keratometer readings of the treatment zone of the post refractive surgical cornea to be used for the base curve; using fitting set lenses to determine the fit of the anterior surface of the lens having a multifocal segment that is an aspheric central zone to provide near and intermediate vision and a spherical portion to provide distance vision adjacent the aspheric central zone using a center aspheric addition resulting in a lens that gives true continuous vision through near, intermediate, and distance vision zones.
