Abstract: Methods of manufacturing hybrid contact lenses using a mold are provided. The methods include pouring liquefied resin of a substantially rigid material within an inner section, curing the substantially rigid material, pouring liquefied resin of a substantially flexible material within an outer section and curing the substantially flexible material. In some embodiments, a wall disposed between the rigid and flexible materials is angled and/or bent to increase bonding strength between the rigid and flexible sections. The curing steps involve the application of heat, UV light, or a combination of both heat and UV light.

Abstract: A hybrid hard-soft contact lens is provided. Several embodiments of the invention include methods of coupling the hard and soft sections of the contact lens. Other embodiments of the invention include contact lens materials and coatings that increase oxygen transmission though the lens. Yet other embodiments of the invention are directed to cost-effective manufacturing methods of a hybrid hard-soft contact lens. This Abstract is provided for the sole purpose of complying with the Abstract requirement rules that allow a reader to quickly ascertain the subject matter of the disclosure contained herein. This Abstract is submitted with the explicit understanding that it will not be used to interpret or to limit the scope or the meaning of the claims.

Abstract: A hybrid contact lens comprises a substantially rigid zone having a base curve and a substantially flexible hydrophilic portion coupled to the substantially rigid zone, wherein the substantially flexible portion has one of a plurality of radii.

Abstract: A hybrid contact lens comprises a central zone comprising a substantially rigid, gas permeable material having a DK of at least 30, a relatively soft peripheral zone and an intermediate zone comprising a film or coating that is created around the central zone, and then cured. The film facilitates chemical bonding between the central zone and the peripheral zone, and also provides a protective barrier to prevent modification of the physical characteristics of the central zone. The film may be created by soaking the central zone in a chemical solution for a predetermined amount of soaking time.

Abstract: Apparatus and methods are provided for reducing or eliminating the progression of myopia, including a lens having an intentionally created aberration pattern for reducing or eliminating the progression of myopia. The aberration pattern may comprise a positive spherical aberration that produces a wavefront error in which the paracentral wavefront is disposed in front of the retina, thereby producing a signal that counters axial length growth of the eye and preventing the progression of myopia.

Abstract: A method of manufacturing a hybrid contact lens having a substantially rigid center portion and a substantially flexible outer portion, comprising forming the substantially rigid center portion, treating the substantially rigid center portion to form a coating on the perimeter of the substantially rigid portion, forming the substantially flexible outer portion around the substantially rigid center portion and chemically bonding the substantially flexible portion to the substantially rigid portion. Hybrid lenses comprising a substantially rigid center portion and a substantially flexible outer portion joined at junction comprising a first segment and a second segment are also provided.

Abstract: The present invention is directed to a contact lens design and methods of manufacturing, fitting and using such lenses. As an example, the contact lens may be designed to be used in an orthokeratology treatment program. The contact lens according to the invention overcomes the deficiencies of the prior art, and provides a design which allows proper fitting of a patient, whether for corrective contact lenses or for use in an orthokeratology treatment program. The ability to properly fit a patient will alleviate, at least to a great degree, corneal abrasions from poorly distributed bearing, corneal warpage from decentered lenses, edema from tight fitting lenses and discomfort. The design allows a great deal of flexibility to the fitter to enhance the functionality of the lens. The lens of the present invention includes a central zone and first annular zone located adjacent to and concentrically around the central 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: Certain embodiments include medical devices for capturing images of a localized portion of a body, such as the eye or skin tissue. An exemplary system utilizes a hand-held portable viewer. Various embodiments of the viewer have telecentric optics with a focal length of between about six inches and about twelve inches. The viewer also includes an image sensor adapted to capture an image of the object being studied, and may include one or more illumination sources selectively operable to illuminate the object. A light meter that measures a light level reflected from the object and a level that measures a rotational position of the viewer relative to a reference level position may be included. One or more filters may be removably fastenable to the viewer to cover the illumination source or sources and/or the aperture.
