An intraocular device that includes a fluid lens is provided. The fluid lens has an anterior side and posterior side that can be coupled together to form a closed cavity therebetween that can be filled with a liquid material. A channel can be formed in the posterior side that is configured to receive a joining substance that bonds the anterior side to the posterior side and inhibit the unintended spread of the joining substance. A syringe can be extended through a port in the fluid lens to flow liquid material into the closed cavity. Subsequently, a plug can be inserted into the port to prevent the escape of the liquid material.

A method of modifying a refractive profile of an eye having an intraocular device implanted therein, wherein the method includes determining a corrected refractive profile for the eye based on an initial refractive profile, identifying one or more locations within the intraocular device based on the corrected refractive profile, and directing a pulsed laser beam at the locations to produce the corrected refractive profile. A system of modifying an intraocular device located within an eye, wherein the system includes a laser assembly and a controller coupled thereto. The laser assembly outputs a pulsed laser beam having a pulse width between 300 picoseconds and 10 femtoseconds. The controller directs the laser assembly to output the pulsed laser beam into the intraocular device. One or more slip zones are formed within the intraocular device in response thereto, and the slip zones are configured to modify a refractive profile of the intraocular device.

An accommodating (re-focusable) lens system a body of which includes, upon being assembled, first and second individual lenslets having first and second optical portions sequentially disposed along an optical axis. Change in optical-power accommodation of the system is achieved by changing an applanated area of contact between the lenslets in response to force applied to the lenslets and transformed into an axial force. In specific case, the first and second lenslets form an intraocular lens (IOL) and have respective haptic portions, interlocked as a result of rotating of one lenslet with respect to another such as to bring first and second lenslets in contact at an axial point. The applanated area of contact is changed, then, in response to a radially-directed force caused by a change of distance between the interlocked ends of the haptics and transferred to the optical portions through the interlocked haptics. When installed in a natural lens capsule after the cataract extraction, the optical power of such IOL is gradually modifiable due to a change of curvature of the capsule caused by operation of a ciliary muscle.

The invention is directed to an intraocular lens having an optical body, two haptic elements and first and second sets of a plurality of ropes corresponding to respective ones of the first and second haptic elements. The ropes are secured to the optical body and to the haptic element and have a severing sequence. The haptic elements each have a compressed state, a partly compressed state and an uncompressed state. In the compressed state, the first rope of the severing sequence is configured to deform the haptic element in a direction toward the optical body as a result of which the first rope is under a tensile stress and the rest of the ropes are stress-free and, by the ropes being severed successively in the severing sequence, the haptic element can be brought firstly to the partly compressed state. All the ropes are severed in the uncompressed state.

An accommodative intraocular lens capable of effectively exerting a focus adjustment function includes an optical portion and a plurality of support portions arranged around the optical portion. The support portion includes an anterior support portion and a posterior support portion, and the anterior support portion presses an anterior capsule and the posterior support portion presses a posterior capsule by the elastic force of the support portion. When the lens capsule is in a distance vision state or in a near vision state, as the pressing force of the anterior capsule against the anterior support portion increases or decreases, the anterior support portion deflects backward or returns forward while maintaining the radial position of the base end portion, so that the tip end portion of the anterior support portion moves backward or forward greatly while maintaining the radial position, and the optical portion moves backward or forward accordingly.

Accommodating intraocular lens

An intraocular lens (IOL) for implantation within a capsular bag of a patient's eye comprises an optical structure and a haptic structure. The optical structure comprises a planar member, a plano convex member, and a fluid optical element defined between the planar member and the plano convex member. The fluid optical element has an optical power. The haptic structure couples the planar member and the plano convex member together at a peripheral portion of the optical structure. The haptic structure comprises a fluid reservoir in fluid communication with the fluid optical element and a peripheral structure for interfacing to the lens capsule. Shape changes of the lens capsule cause one or more of volume or shape changes to the fluid optical element in correspondence to deformations in the planar member to modify the optical power of the fluid optical element.
