US 12,496,790 B2 · Customized manufacture of molds for making wavefront-customized contact lens using a wavefront aberrometer

Abstract

Systems and methods for manufacturing a wavefront-customized contact lens. The systems include: (1) an optical instrument for measuring ocular imperfections of a patient's eye; (2) a computer for designing a mold and pin design used for manufacturing a wavefront-customized contact lens that corrects the ocular imperfections; (3) a fabrication machine for fabricating a wavefront-customized mold that includes corrections for the ocular imperfections; and (4) a manufacturing equipment for manufacturing a wavefront-customized contact lenses that uses the wavefront-customized mold; wherein the wavefront-customized mold design and wavefront-guided contact lens manufacturing are uniquely customized for each patient's eye. The optical means can be a wavefront aberrometer with, or without, a profilometer and/or an Optical Coherence Tomography (OCT) module. The wavefront-customized contact lens can be a soft contact lens or a rigid, gas permeable contact lens.
