Modular intraocular implant

An adjustable ocular insert to be implanted during refractive cataract surgery and clear (human) crystalline lens refractive surgery and adjusted post-surgically. The implant comprises relatively soft but compressible and resilient base annulus designed to fit in the lens capsule and keep the lens capsule open. Alternatively the annulus may be placed in the anterior or posterior chamber. The annulus can include a pair of opposed haptics for secure positioning within the appropriate chamber. A rotatable annular lens member having external threads is threadedly engaged in the annulus. The lens member is rotated to move the lens forward or backward so to adjust and fine-tune the refractive power and focusing for hyperopia, myopia and astigmatism. The intraocular implant has a power range of approximately +3√0π−3 diopters.

Masked intraocular implants and lenses

Intraocular implants and methods of making intraocular implants are provided. The intraocular implants can improve the vision of a patient, such as by increasing the depth of focus of an eye of a patient. In particular, the intraocular implants can include a mask having an annular portion with a relatively low visible light transmission surrounding a relatively high transmission central portion such as a clear lens or aperture. This construct is adapted to provide an annular mask with a small aperture for light to pass through to the retina to increase depth of focus. The intraocular implant may have an optical power for refractive correction. The intraocular implant may be implanted in any location along the optical pathway in the eye, e.g., as an implant in the anterior or posterior chamber.

Accommodating Intraocular Lens

InactiveUS20100228344A1Minimal incisionSimplified lens exchangeIntraocular lensIntraocular lensCataract surgery
A deformable intracapsular implant device for shaping an enucleated lens capsule sac for use in cataract procedures and refractive lensectomy procedures. In one embodiment, the intraocular implant devices rely on thin film shape memory alloys and combine with the post-phaco capsular sac to provide a biomimetic complex that can mimic the energy-absorbing and energy-releasing characteristics of a young accommodative lens capsule. In another embodiment, the capsular shaping body is combined with an adaptive optic. The peripheral capsular shaping body carries at least one fluid-filled interior chamber that communicates with a space in a adaptive optic portion that has a deformable lens surface. The flexing of the peripheral shaping body in response to zonular tensioning and de-tensioning provides an inventive adaptive optics mechanism wherein fluid media flows between the respective chambers “adapts” the optic to increase and decrease the power thereof. In one embodiment, the capsular shaping body carries a posterior negative power adaptive optic that can be altered in power during accommodation to cooperate with an independent drop-in exchangeable intraocular lens.

Intraocular lens implant having accommodative capabilities

An intraocular implant including a lens and a shell component. The shell component includes a shell peripheral wall encompassing a shell inner volume for protectively enclosing the lens and allowing the latter to move therein between lens accommodating positions. The lens is pivotable within the shell inner volume between a lens first position wherein the lens is in a substantially proximal relationship relative to a shell wall first segment and a lens second position wherein the lens is in a substantially proximal relationship relative to a shell wall second segment. In one embodiment of the invention, the lens peripheral edge defines a lens edge pivot portion and the shell segment joining edge defines a corresponding shell edge pivot portion, the lens and shell edge pivot portion being complementarily configured and sized so that when the lens abuttingly rests against the peripheral wall inner surface, the lens and shell edge pivot portions interact with each other for allowing the lens to pivot between the lens first and second positions.In another embodiment of the invention, the lens is pivotally suspended within the shell component for pivotal movement between the lens first and second position. In both embodiments, the lens may also pivot to a lens intermediate position in a spaced relationship relative to both the the shell wall first and second segments.

Extended depth of field optics for human vision

The present invention provides extended depth of field to human eyes by modifying contact lenses, intraocular implants, and / or the surface of the eye itself. This may be accomplished by applying selected phase variations to these optical elements (e.g., by varying surface thickness of the cornea of the eye). The phase variations EDF-code the wavefront and cause the optical transfer function to remain essentially constant within a range of distances from the in-focus position. This provides a coded image on the retina. The human brain decodes this coded image, resulting in an in-focus image over an increased depth of field.

Apparatus und Method for Rendering a Virtual Monitor on Smart Ophthalmic Devices in Augmented Reality Environments

An apparatus and a method are described herein related to the art of augmented reality type monitor virtualization. A monitor-virtualization system, such as a head-mountable device, an ophthalmic device or an intraocular implant, can render a virtual monitor in augmented reality. A liquid lens or an optical phased array can position the virtual monitor in space by optical means. A dimmable occlusion matrix can be additionally operated such as to make the image of the virtual monitor substantially opaque. A coordinator module can synchronize the activities of monitor positioning and occlusion masking. The virtual monitor can be anchored to real-world artifacts using bokode technology. Various dimming modes of the occlusion matrix reduce operator fatigue. The apparatus may operate in smart sunglass mode when the virtual monitor function is paused. The virtual monitor can be hidden or visualized differently when thresholds in terms of user geolocation or viewing angle are breached.
