COMPOSITIONS, SYSTEMS AND METHODS FOR PATIENT SPECIFIC OPHTHALMIC DEVICE

Systems, methods, and devices to fabricate one or more device components are disclosed. An example method includes fabricating one or more subject specific device components generated from receiving one or more images of one or more features of the first eye of the subject; designing a three dimensional virtual geometric model of the ophthalmic device using the one or more images; generating a plurality of virtual cross-sections of the three-dimensional virtual geometric model, wherein the cross-sections are defined by a set of physical parameters derived from the three-dimensional model; and fabricating the one or more subject specific features using the plurality of virtual cross-sections of the three dimensional model to direct an additive manufacturing method.

METHOD FOR OBTAINING CONTACT LENSES WITH DYNAMICALLY CONTROLLED SAGITTA AND CLEARANCE
20230084398 · 2023-03-16 ·

The disclosure generally describes methods, systems and products relating to the development and manufacture of scleral contact lenses. A number of dimensions for the scleral lens is generated based on control points and attendant curvature parameters. Any change to one or more of the curve parameters imparts an improved anterior and posterior surface of the scleral lens and associated thickness, while undesired modifications to control points and other curve parameters remain static inasmuch as the sagittal depth component is an input parameter of the present disclosure.

CUSTOMIZED MANUFACTURE OF MOLDS FOR MAKING WAVEFRONT-CUSTOMIZED CONTACT LENS USING A WAVEFRONT ABERROMETER

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.

Prosthetic lenses and methods of making the same

Aspects of the disclosure provide for a method of creating a lens. Examples of the method include identifying a limbal zone of the eye, determining a back optic zone within the limbal zone, determining a front optic zone based at least partially on the limbal zone, computing a lens surface of the lens based at least partially on the limbal zone, the back optic zone, and the front optic zone, de-centering at least one of the back optic zone or the front optic zone from a visual axis or a spindle axis of the lens.

Prosthetic lenses and methods of making the same

An optical device comprising a lens configured to be disposed in an eye. The lens is configured to contact a sclera of the eye and have a clearance above a cornea of the eye when disposed in the eye. The lens comprises a back surface that comprises at least one non-symmetrical feature that is configured to engage a corresponding feature on the eye. The lens is configured to be rotationally stable in use based on the at least one non-symmetrical feature on the back surface of the lens.
