Provided is an intraocular lens affixing device which makes it possible to affix an intraocular lens of any kind with respect to the inside of an eye with a ruptured or deleted lens capsule. The intraocular lens affixing device 1 is provided with a device support portion (A) and an intraocular lens housing portion (B) connected to the device support portion (A). The device support portion (A) includes a frame 2 having a shape matching a ciliary sulcus 36. Also provided is an affixing kit for inserting an intraocular lens, the kit being provided with a) an intraocular lens affixing device; and b) an injector for injecting the affixing device.
DELIVERY DEVICES FOR IMPLANTATION OF INTRAOCULAR LENS SUPPORT DEVICES AND METHODS OF USE
An insertion tool for delivering an implantable lens support device into an eye having a proximal end region; a distal end region having a distal hook; and an intermediate region connecting the distal end region to the proximal end region, the intermediate region being substantially planar. The distal end region and intermediate region are sized for insertion through a clear corneal incision. Related tools, methods, and devices are provided.
DEVICES TO SUPPORT AND POSITION AN INTRAOCULAR LENS WITHIN THE EYE AND METHODS OF USE
An implantable device for supporting an intraocular lens in an eye including a lens support structure having a central aperture; and one or more fixation arms coupled to the lens support structure and configured to locate and stabilize the device within the eye. Related tools, systems, and methods are provided.
INTRAOCULAR LENS INSERTION APPARATUS
An intraocular lens insertion apparatus which allows the intraocular lens to behave more stably. The intraocular lens insertion apparatus includes a substantially tubular apparatus body which has, at a tip end thereof, an insertion tube part for inserting an intraocular lens in a folded state into an eye, the intraocular lens having a lens body and a support, a storage which stores the intraocular lens, and an extruding member which moves the intraocular lens in the insertion tube part by pushing the intraocular lens, and the extruding member has a tip end part having a first protrusion protruding to one side in a left-right direction and a second protrusion protruding to the other side in the left-right direction.
Intraocular lens injector
Apparatuses, systems, and methods for implanting an intraocular lens into an eye are described. For example, an intraocular lens injector may include a passage formed in a distal end portion of the intraocular lens injector. The passage may define an interior surface, and one or more rails may be formed on the interior surface so as to displace an optic of an intraocular lens (IOL) being advanced through the passage towards a portion of the interior surface disposed opposite the one or more rails.
Devices to support and position an intraocular lens within the eye and methods of use
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.
INTRAOCULAR LENSES WITH EMBEDDED INTRAOCULAR PRESSURE SENSORS
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.
METHOD OF IMPLANTATION OF AN INTRAOCULAR LENS IN A CILIARY SULCUS OF AN EYE
A method for the correction of the near vision of a patient suffering from age-related macular degeneration (AMD) and having a pseudophakic eye having at least one primary intraocular lens (IOL) implanted in a capsular bag in a posterior chamber of the eye, comprising: implanting a secondary IOL, made from a foldable soft material, between an iris of the eye and the primary IOL, wherein the secondary IOL comprises an optically active lens part having an optical axis and a plurality of evenly spaced haptics around the optically active lens part, the optically active lens part having a central optical lens portion and a peripheral optical lens portion surrounding the central optical lens portion, the central optical lens portion being a positive lens and having a refractive power that differs from a refractive power of the peripheral optical lens portion by +5 diopters up to +25 diopters, placing the central optical lens portion of the secondary IOL in an aligned position optically coaxial to the at least one primary IOL for magnifying and focusing an image projected by the central lens portion through the at least one primary IOL on a fovea of a retina of the eye, and fixing the secondary IOL in the aligned position by arranging the plurality of haptics behind the iris in a ciliary sulcus of the eye.
SYSTEMS AND METHODS FOR FORMING OPHTHALMIC LENS INCLUDING META OPTICS
Ophthalmic lenses and methods of manufacture thereof are disclosed. The ophthalmic lenses include metasurface features that define a metasurface array on a lens body. The metasurface array can be tuned to modify an optical property, such as glare reduction, of the ophthalmic lens using an arrangement of metasurface building elements dimensioned from an optical wavelength, including being dimensioned smaller than an optical wavelength. The ophthalmic lenses can be subject to physical manipulation, including rolling or other folding during an installation procedure, and as such, the modified optical property induced by the metasurface array can be maintained after such manipulation. The ophthalmic lenses can be formed using a molding process, in which the metasurface array is associated with a non-solid material and formed into a lens shape with the material.
Ophthalmosurgical injector system
An ophthalmosurgical injector system includes an injector, which has a handpiece, a plunger, and a dispensing device; an intraocular lens, which has an optic body and two C-shaped haptic arms protruding therefrom; and a cartridge, in which the intraocular lens is received. The dispensing device has an inlet opening at the proximal end and an outlet opening at the distal end. When the plunger is moved forward, the intraocular lens is conveyed from the cartridge through the inlet opening to the outlet opening of the dispensing device. When the intraocular lens is held in the cartridge in a compressed and preloaded state, a subregion of each of the haptic arms bears on and covers the optic body. In a plan view, the optic body of the preloaded intraocular lens has a circular surface area with a diameter of at least 4.0 mm that is not covered by the haptic arms.
