SYSTEMS AND METHODS FOR CORRECTING POWER OF AN INTRAOCULAR LENS USING REFRACTIVE INDEX WRITING

Systems and methods for improving vision of a subject implanted with an intraocular lens (IOL) that has a non-zero residual spherical error that requires an estimated diffractive power addition in the IOL. In some embodiments, a plurality of laser pulses are applied to the IOL, the laser pulses being configured to produce, by refractive index writing on the IOL, the estimated diffractive power addition to correct for the residual spherical error.

Accommodating Intraocular Lens with Rigid Tapered Flanges

Disclosed are accommodating intraocular lenses with a variable power lens and a lens driver coupled to the variable power lens. The driver is arranged to be, at least partially, positioned in an accommodative structure of the eye, for example the sulcus of the eye or the capsular bag of the eye with the driver including a tapered flange which tapers towards its peripheral free end to provide translation of constrictive movement of the accommodative structure in an axial direction into movement onto the variable power lens in a lateral direction.

ACCOMMODATIVE INTRAOCULAR LENS

An accommodative intraocular lens includes a first lens part, a haptic, and a flexible membrane. The flexible membrane is arranged adjacent to a distal optical body surface, delimits a cavity together with the distal optical body surface and is transparent to light. A second lens part has a hollow cylinder coupled releasably to the first lens part, as a result of which the intraocular lens can be brought into a coupling state in which the second lens part is arranged on a distal side of the first lens part and the hollow cylinder is configured to deform the membrane by a longitudinal displacement of the hollow cylinder parallel to the optical axis. The hollow cylinder has on its exterior an outer face and a bearing face arranged adjacent to a proximal end of the outer face and encloses, with the outer face, an angle of less than 180°.

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.

High definition and extended depth of field intraocular lens

A virtual aperture integrated into an intraocular lens is disclosed. Optical rays which intersect the virtual aperture are widely scattered across the retina causing the light to be virtually prevented from reaching detectable levels on the retina. The use of the virtual aperture helps remove monochromatic and chromatic aberrations yielding high-definition retinal images. For a given definition of acceptable vision, the depth of field is increased over a larger diameter optical zone. In addition, thinner intraocular lenses can be produced since the optical zone can have a smaller diameter. This in turn allows smaller corneal incisions and easier implantation surgery.

Intraocular lens delivery device and method of use

An IOL delivery device which has a macro movement actuator which is actuateable to move an IOL into position in the device for the IOL to be delivered, and a micro movement actuator comprising at least one pivotable member which is pivotable to deliver the IOL to the eye. The pivotable member may comprise one or more wheels that are rotatable using one's finger.

Telescopic Optical Components for Evaluating Photic Effects of Intraocular Lenses

An apparatus uses optical components arranged as a telescope to simulate the optical effects of intraocular lenses on images viewed in the presence of scattering light and glare sources. By simulating a view of a real image through an intraocular lens and projecting the simulated view into a patient’s eye, the patient can view the quality of vision that may result from use of a particular lens as a corrective tool. The intraocular lens is placed within the fields of view of peripheral optical components having prescribed operating parameters that allow for projecting a simulated image through an intraocular lens into a patient’s eye before the intraocular lens is implanted. The patient can perceive the results of a corrective lens before that lens is attached to or implanted within the patient’s eye.
