A prosthetic capsular device configured to be inserted in an eye includes a housing structure and a ring structure. The housing structure includes a first side, a second side opposite the first side, a third side, a fourth side opposite the third side, a posterior side including a refractive surface, an anterior side opposite the posterior side, and a longitudinal axis. The first side, the second side, the third side, the fourth side, the posterior side, and the anterior side at least partially define a cavity configured to contain an intraocular device (e.g., an IOL). The anterior side includes an opening. The ring structure includes a ring structure portion extending radially outward from proximate one of an end of the first side and an end of the second side.

Disclosed herein is an implantable accommodative IOL system for insertion into an eye of a patient, the system comprising: an optical element and a housing including an opaque frame. The optical element comprises an optical lens having variable optical power, and the opaque frame is circumferentially disposed around a periphery of the optical element.

A device for supporting an intraocular lens in an eye. The device has a lens support structure having an inner perimeter surface defining, at least in part, a central opening. When implanted, light may pass through the central opening towards the retina. The device has at least three fixation arms, each having an origin portion coupled to the lens support structure and a terminal portion comprising an anchor for trans-scleral fixation of the device. Prior to implantation, at least one fixation arm is biased towards a folded configuration and has a bend between the origin portion and the terminal portion. The origin portion extends away from the lens support structure and the anchor of the terminal portion is positioned over or under at least one of a portion of the lens support structure and a portion of the central opening. Related tools, systems, and methods are provided.

Implantable pressure sensors and implantable electronics should be packaged in hermetically sealed modules with biocompatible surfaces before being implanted. Packaging designs should be compact and cause little to no interference with the mechanical (and optical) properties or functions of the implant. For a pressure sensor in an intraocular lens, this means that the sensor and packaging should allow the lens to be folded so that it can be implanted through a small incision in the eye. An inventive implantable pressure sensor is coated with a silicone elastomer and hermetically sealed by a multilayer coating of SiO.sub.x and Parylene C, which may also encapsulate other components, including a microcontroller or processor, rechargeable batteries, sensors, resistors, capacitors, wireless transceivers, and/or antennas mounted on a transparent substrate. This combination of silicone gel and multilayer coating isolates the pressure sensor from surrounding tissue while allowing the pressure sensor to measure pressure precisely and quickly.

An intraocular lens system comprising at least one intraocular lens having an anterior surface and a posterior surface, wherein at least one surface of the lens is aspherical to provide for a continuum of retinal images to be focused at the retina in an area between two retinal eccentricities. The system may include an anterior light-converging intraocular lens 16 for positioning within the eye, the anterior lens having an anterior surface and a posterior surface; and a posterior light-diverging intraocular lens 17 for positioning within the eye posterior to the anterior lens, the posterior lens having an anterior surface and a posterior surface; wherein one or both surfaces of the anterior lens and/or one or both surfaces of the posterior lens are aspherical.

IOL of the type which include a lens, haptics and a curving ring wherein there are soft haptics and rigid haptics, both being associated through a lever and wherein a softer outer ring houses in its inner geometry an inner curving ring, the latter being rigid and incomplete, with curving flaps in whose geometry the assembly consisting of lens and haptics is housed.

A suspension system for suspending an intra-ocular lens in the lens capsule of an eye has one or more collapsible cavities formed in the suspension system, each having at least one opening communicating the interior of the cavity with fluid from the interior of the eye, wherein the walls of the cavity exhibit sufficient structural elasticity that they return to their habitual shapes after being compressed by external force.

An apparatus includes an intraocular pseudophakic contact lens having an optical lens and haptics extending radially from the optical lens. The optical lens is configured to at least partially correct a residual refractive error in an eye. The residual refractive error includes a refractive error that exists in the eye after implantation of an artificial intraocular lens in the eye. The haptics are configured to be inserted under an anterior leaflet of a capsular wall in the eye in order to capture and confine the haptics under the anterior leaflet and secure the intraocular pseudophakic contact lens against the artificial intraocular lens. Anterior surfaces of the haptics are configured to contact an inner capsular wall surface at the anterior leaflet. Posterior surfaces of the haptics include ridges configured to capture at least one edge of the artificial intraocular lens in order to secure the intraocular pseudophakic contact lens to the artificial intraocular lens.

There is discloses an iris-lens diaphragm made of elastic material in the form of a colored ring. The iris0lens diaphragm comprises peripheral arc-shaped and open-ended support elements for one-point contact that are capable of bending in the plane of the colored ring, wherein a thickness of support elements exceeds a thickness of the colored ring.

An ophthalmic assembly for implantation in an anterior chamber of an eye of a patient to provide accommodation of the vision to said patient comprises a variable-focus lens and an actuator for modifying the focal length of the variable-focus lens. The ophthalmic assembly comprises an autofocus system configured to determine a distance parameter of an object that the patient's eye is looking at; a signal processing unit arranged to convert said distance parameter into a focal length value of the variable-focus lens; and an actuator control unit configured to control the actuator as a function of the focal length value received from said signal processing unit. A method for accommodating the vision of a patient using an opthamalic assembly is also disclosed.
