Abstract: In exemplary embodiments, this invention comprises a method for communicating the geometry of a contact lens to a manufacturer. The method includes describing the shape of a first zone of a contact lens and describing the shape of a second zone of the contact lens by providing an angle of orientation from a reference point located on the first zone. The method may further include describing the shape of one or more additional zones by providing angles of orientation from a reference point on another zone.

Abstract: The invention is directed to a contact lens design and methods of manufacturing, fitting and using such lenses. The contact lens may be designed for use in a corneal refractive therapy (CRT) program. The lens provides a design which allows proper fitting of a patient, whether for corrective contact lenses or for a CRT program. Due to the rational design of the lenses according to the present invention, a minimal number of lens parameter increments can be identified to cover the range of common corneas. It is therefore possible to provide pre-formed lens buttons or blanks which are easily formed into a final design, thereby simplifying and speeding up the treatment process. Further, any adjustment of the lens design which may be required based upon trial fitting or the like, is easily envisioned and implemented by the fitter.

Abstract: In accordance with exemplary embodiments of the present invention, an eye is presented with a therapeutic optical structure (e.g., corneal reshaping or by way of a contact lens) that focuses the peripheral image field in at least one meridian in front of the mid peripheral retina. In general, the therapeutic optical structure places the peripheral image field with reference to the retina in the direction and amplitude that growth is needed in order that the emerging myopia would be regulated. In accordance with exemplary embodiments of the present invention, an eye is presented with a therapeutic optical structure that further produces a central retinal image that is focused on the central retina in at least one meridian so as to not reshape the central cornea.

Abstract: In accordance with exemplary embodiments, the present invention provides a therapeutic optical device configured to focus the central retinal image in at least one meridian and focus at least one semi-meridian of the peripheral image field in front of or behind the retina to stimulate eye and/or corneal reshaping to reduce astigmatism. In exemplary embodiments, the device further provides rotational stability.

Abstract: In accordance with exemplary embodiments, the present invention provides scleral lenses comprising a central zone and at least one peripheral zone defined by an angle. In an exemplary embodiment, a peripheral zone is curved in either a concave or convex direction or is uncurved. In an exemplary embodiment, the angle for a plurality of semi-meridians or transverse sections can be varied to create a transverse undulation of a peripheral zone. In accordance with exemplary embodiments, the present invention provides scleral lenses that do not demonstrate excessive pressure on the sclera and that allow for post lens tear exchange. The present invention also provides kits of scleral lenses.

Abstract: The present invention is directed toward the design of lenses to incorporate elevation features in at least one annular zone on the posterior surface of the lens that engage the elevation differences of the eye while allowing the central zone of the lens to have conventional spherical, aspheric, multifocal or toric geometry. In various embodiments, lenses according to the present invention are rotationally stable, free of flexure and well centered over the pupil.

Abstract: A system and method for treating and preventing loss of visual acuity. The system comprises a vision correcting lens, such as a contact lens, having a material with a regular pattern of orientation of polarizable molecular bonds, so as to create a birefringent effect. Off-axis light rays are refracted through the contact lens so as to focus in front of the retina, whereas on-axis light rays pass through the contact lens without refraction, such that their focal point on the fovea is unaltered. In an exemplary embodiment, a contact lens of the present invention is capable of independently altering the refractive state of the eye in relation to fovea and peripheral retina so as to simultaneously correcting visual acuity while minimizing the signal for axial growth and hence myopic progression.
