Accommodating soft contact lens
First Claim
1. An accommodating contact lens comprising:
- an optical chamber,a plurality of eyelid-engaging chambers coupled to the optical chamber, anda plurality of channels coupled to the plurality of eyelid-engaging chambers to couple the plurality of eyelid-engaging chambers to the optical chamber,wherein the plurality of eyelid engaging chambers is arranged to be selectively engaged with an eyelid in order to provide incremental increases in optical power,wherein the plurality of eyelid engaging chambers comprises a first chamber and a second chamber, andwherein the first chamber and the second chamber are arranged to engage the first chamber with the eyelid before the second chamber in order to provide a first amount of intermediate vision correction when the first chamber is engaged, and to engage the second chamber and the first chamber together with the eyelid to provide a second amount of optical correction corresponding to near vision correction.

Abstract
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.
