Contact lenses incorporate high plus or add power profiles that at least one of slow, retard or preventing myopia progression and minimize halo effect. The lens includes a center zone with a negative power for myopic vision correction; and at least one treatment zone surrounding the center zone, the at least one treatment zone having a power profile that increases from an outer margin of the center zone to a positive power within the at least one treatment zone of greater than +5.00D.

An orthokeratology lens designating system 10 includes a selecting device 20, a database server 30, a lens designating server 50 and a terminal device 70. The selecting device 20 includes a device 22 for acquiring movement data of an orthokeratology lens moving on a cornea with the orthokeratology lens mounted on the cornea, and an assessing device 28 for assessing, on the basis of the lens movement data, that the orthokeratology lens is a registered lens that can be used for a patient. Registered lens correction D data of the registered lens, registered patient data including registered cornea D data of a cornea, and registration stage data that indicates in which stage of a plurality of correction stages, the lens is to be mounted on the cornea, are output to the database server 30. The database server 30 is configured to accept and store these pieces of data to build a database. The terminal device 70 includes a patient data acquiring device 71 and a patient stage data accepting means, and is capable of transmitting patient data and patient stage data to the lens designating server 50. The lens designating server 50 is configured to retrieve from the database a registered lens having registered data that are the same as or close to the received patient data and patient stage data, and to designate the retrieved registered lens as the orthokeratology lens to be used for the patient.

The stabilized contact lens methods and apparatus disclosed herein provide improved stabilization of a contact lens placed on a cornea of an eye. The contact lens comprises stabilization zones that allow the lens to repeatedly and consistently orient on the cornea such that a sensing zone located on the lower portion of the lens is located inferiorly to engage the lower eyelid. The stabilized contact lens can provide a lower pressure sensing zone with decreased thickness for pressure or other sensing related to the lower eyelid. The decreased thickness has the advantage of improving coupling between forces from an eyelid and a lower chamber of a fluidic module. The improved coupling allows increased amounts of fluid to move between the lower chamber and an upper optical chamber coupled to the lower chamber, such that the upper chamber can increase curvature and optical power in response to pressures of the eyelid.

The present disclosure relates to ophthalmic devices such as ophthalmic lenses. An ophthalmic device may comprise an ophthalmic lens for at least one of slowing, retarding or preventing myopia progression. The ophthalmic lens may comprise a center zone with a negative power for myopic vision correction; and at least one treatment zone surrounding the center zone, the at least one treatment zone having a power profile comprising an ADD power, the at least one treatment zone having a surface shape comprising a portion of a generally toroidal shape, wherein the at least one treatment zone is arranged as to form a continuous surface with the center zone.

An accommodating contact lens comprises a variable focus optical module, which comprises an optical chamber and one or more eyelid engaging chambers coupled to the optical chamber with one or more extensions comprising channels extending between the optical chamber and the more eyelid engaging chambers. The module may comprise a self-supporting module capable of supporting itself prior to placement in a contact lens to facilitate placement prior to encapsulation in the contact lens. The module may comprise one or more optically transmissive materials, provides improved optical correction, and can be combined with soft contact lens materials such as hydrogels. In many embodiments, the module comprises a support structure extending between an upper membrane and a lower membrane in order to provide variable optical power accurately with decreased amounts distortion and improved responsiveness to eyelid induced pressure.

A lens comprises an internal cavity structure formed by dissolution of a soluble insert material. The internal soluble material may dissolve through a body of a lens such as a contact lens in order to form the cavity within the contact lens. The cavity within the lens can be shaped in many ways, and corresponds to the shape of the dissolved material, such that many internal cavity shapes can be readily fabricated within the contact lens. The insert can be placed in a mold with a pre-polymer material, and the pre-polymer material cured with the insert placed in the mold to form the lens body. The polymerized polymer may comprise a low expansion polymer in order to inhibit expansion of the lens when hydrated. The polymer may comprise a hydrogel when hydrated. The soft contact lens material comprises a sufficient amount of cross-linking to provide structure to the lens and shape the cavity.

An ophthalmic device having posterior and anterior features are disclosed herein. An example ophthalmic device may include an enclosure having an insert disposed therein. The enclosure may include a cornea contact disposed on a posterior side and arranged to rest on a user's cornea outside of a central cornea area when the ophthalmic device is worn by a user. The enclosure further includes a channel formed in the posterior side, where the channel extends through the cornea contact from at least radially outside of the insert to an inner edge of the cornea contact.

Disclosed herein is a contact lens comprising a rounded, minus-carrier, lenticular-like curve over a central, upper portion of the lens that allows the contact lens to translate upwards in downgaze.

A mold for a front curve of an ophthalmic lens includes an inner region having a non-rotationally symmetric shape, an outer region having a rotationally symmetric shape, and a continuous middle region between the inner region and the outer region. A first portion of the middle region is in contact with the inner region, defining a non-rotationally symmetric rim or edge of a front surface of the ophthalmic lens. A second portion of the middle region is in contact with the outer region and is rotationally symmetrical.

Ophthalmic lenses are described herein. An example ophthalmic lens may comprise a first surface. The example ophthalmic lens may comprise a second surface disposed opposite the first surface and defining a volume of lens material therebetween. A thickness profile of the volume of lens material may be derived from one or more eyelid profiles such that a thickness gradient of the volume of lens material is oriented to be substantially orthogonal to a target eyelid margin shape.
