A prosthetic capsular device configured to be inserted in an eye after removal of a lens, in some embodiments, can comprise a housing structure comprising capable of containing an intraocular device and an equiconvex refractive surface. The housing structure can comprise an anterior portion comprising an anterior opening, a posterior portion comprising a posterior opening, and a continuous lateral portion between the anterior portion and the posterior portion.

An eye-implantable electrowetting lens can be operated to control an overall optical power of an eye in which the device is implanted. A lens chamber of the electrowetting lens contains first and second fluids that are immiscible with each other and have different refractive indexes. By applying a voltage to electrodes of the lens, the optical power of the lens can be controlled by affecting the geometry of the interface between the fluids. To prevent fouling the surface due to folding or other manipulation of the lens during the insertion process, one or more surfaces within the lens chamber is highly underwater oleophobic.

An accommodating intraocular lens (AIOL) for implantation within a capsular bag of a patient's eye comprises first and second components coupled together to define an inner fluid chamber and an outer fluid reservoir. The inner region of the AIOL provides optical power with one or more of the shaped fluid within the inner fluid chamber or the shape of the first or second components. The fluid reservoir comprises a bellows region with one or more folds of the bellows extending circumferentially around an optical axis of the eye. The bellows engages the lens capsule, and a compliant fold region between the inner and outer bellows portions allows the profile of the AIOL to deflect when the eye accommodates for near vision. Fluid transfers between the inner fluid chamber and the outer fluid reservoir to provide optical power changes when the eye accommodates.

The subject matter of the disclosure relates generally to a MEMS-based position-sensing system and lenses, for example, contact lenses and intra-ocular lenses, manufactured with the position-sensing system employing one or more angular and/or linear accelerometers and/or pressure transducers and methods for detecting position and motion of an eyeball and/or head utilizing the position-sensing contact lenses.

An intraocular lens includes an annular housing coupled to a first window to form a lensing cavity. Disposed within the lensing cavity is two immiscible liquids, including a first liquid and a second liquid which form a meniscus at an immiscibility interface between the first liquid and the second liquid within the lensing cavity. The intraocular lens includes a flexible reservoir to store a variable portion of the first liquid. The flexible reservoir is disposed about at least a portion of a periphery of the annular housing. The intraocular lens also includes at least one channel linking the flexible reservoir to the lensing cavity to permit a transfer of the first liquid between the flexible reservoir and the lensing cavity. The transfer of the first liquid changes a curvature of the meniscus to adjust optical power of the intraocular lens.

An improved posterior chamber phakic intraocular lens (PCP-IOL) having a haptic with a collar, self-adjusting struts, and lens is disclosed. Haptic or lens of the PCP-IOL may include a protected orifice. A disclosed PCP-IOL may be configured to fit anatomy of varying sizes, and may be self-centering; additionally, a PCP-IOL as set forth herein may allow peripheral aqueous flow between anterior and posterior chambers of a patient's eye.

Disclosed herein are intraocular lenses with features that counteract the effects of anterior capsular contraction and methods for implanting such intraocular lenses. In some embodiments, the intraocular lenses can comprise an optic fluid chamber and a haptic having a haptic fluid lumen in fluid communication with the optic fluid chamber. The haptic fluid lumen can comprise a thickened anterior portion such that a thickness of the anterior haptic wall of the haptic is greater than the thickness of the posterior haptic wall. Moreover, the intraocular lenses can comprise one or more support columns disposed within the haptic fluid lumen. The support columns and/or the thickened anterior portion of the haptic can maintain a shape of the haptic fluid lumen in response to forces applied to the haptic as a result of anterior capsular contraction.

Disclosed herein are intraocular lenses comprising an optic portion and at least one haptic having a proximal end coupled to the optic portion and a distal end. The haptic comprising a haptic lumen extending through at least part of the haptic. The haptic can comprise one or more haptic isolators disposed within the haptic lumen. The one or more haptic isolators can be configured to counteract or reduce unintended shape changes caused by an external energy directed at the haptic.
