Posterior Chamber Phakic Intraocular Lens
The present invention relates to a posterior chamber phakic intraocular lens (1) comprising a central optical part (2), a peripheral haptic part (3) having distal support elements (4) arranged for supporting the intraocular lens (1) on a ciliary zonule, elongated flexible footplates (5) mounted on the support elements (4), each having a distal lateral border (53) arranged for stabilizing the intraocular lens (1) into a ciliary body (98), and manipulation pockets (6) on a surface of the support elements (4), each being associated with one of the elongated flexible footplates (5).
THREE-DIMENSIONAL INTRAOCULAR LENS SCAFFOLD AND ADD-IN LENS COMBINATION AND METHODS OF IMPLANTATION
Devices and methods for replacing a human lens after cataract surgery. The device is an insert for the eye capsule and is formed of two or more rings that are connected to one another. A primary lens is affixed to the insert. A secondary add-in lens can be added to the insert in a subsequent surgery to correct, or further optimize, the optical results obtained with the initial surgery.
INTRAOCULAR LENS WITH A SPREADABLE HAPTIC
Provided is an intraocular lens having an optical body and having at least one haptic element coupled to the optical body, wherein the at least one haptic element has a first haptic component and at least a second haptic component formed adjacent thereto, which is movable elastically relative to the first haptic component, and having a principal optical axis that penetrates through a front side and a reverse side of the optical body, wherein the haptic element, measured in the direction of the principal optical axis, has a maximum of a first height, wherein the second haptic component is displaceable relative to the first haptic component from a non-spread position to a spread position in such a way that the haptic element, measured in the direction of the principal optical axis, attains a maximum of a second height which is greater than the first height, and, in the spread position, the second haptic component can be locked in place relative to the first haptic component, wherein the first haptic component has at least a first spreading element, and the second haptic component has at least a second spreading element, wherein the first spreading element and the second spreading element, viewed in circumferential direction around the principal optical axis, at least in the spread position, are in a mutually overlapping arrangement and directly adjacent to one another at least in some regions.
NEGATIVE POISSON`S RATIO MATERIALS FOR INTRAOCULAR LENSES
An intraocular lens includes a substantially circular lens element formed of a transparent material and one or more haptics extending outwardly from an outer edge of the lens element. The one or more haptics are formed of a polymer foam material having a negative Poisson's ratio (NPR) and are configured to couple the intraocular lens to an eye of a patient. The lens includes an inner region having a first index of refraction and an outer region disposed circumferentially surrounding the inner region, the outer region having a second index of refraction different from the first index of refraction.
Lens case and lens delivery system
The invention relates to a lens case (50, 150) for accommodating an intraocular lens, IOL (1). The lens case (50, 150) comprises a lens case body (3, 103) and a sliding element (4, 104) which can slide on the lens case body from a first position to a second position. The lens case body (3, 103) comprises a longitudinal recess (32, 132), having a first part (32a, 132a) and a second part (32b, 132b), the first part (32a, 132a) being adapted to receive a side zone of the IOL (1) comprising at least one haptic (2), the second part (32b, 132b) being adapted to receive a narrower central zone of the IOL (1). The sliding element (4, 104) comprises a bolt (5, 105a) arranged adjacent a loading port (34, 134) of the second part (32b, 132b) of the recess (32, 132) for displacing the IOL (1) within the recess (32, 132).
Haptic optic management system utilizing rotary arms
Systems, methods, and devices for inserting an intraocular lens (IOL) assembly into an eye may be provided. An example optic management system may include a housing having a first end and a second end and a first side extending between the first end the second end. The housing may include a cavity formed in the first side of the housing and configured to accommodate an intraocular lens, wherein the cavity comprises a first end portion, a second end portion, and a central portion. The housing may further include a bore formed in the housing, wherein a first portion of the bore extends from the first end to the cavity. The haptic optic management system may further include a ceiling disposed on the first side of the housing. The haptic optic management system may further include arms pivotably coupled to the housing in the cavity.
MODULAR INTRAOCULAR LENS DESIGNS, TOOLS AND METHODS
Modular IOL removal systems and methods that cut an optic portion of an intraocular in a single motion such to facilitate removal of the optic portion from an eye through an incision, for example a corneal incision, without increasing the size of the corneal incision. Various cutting tools having one or more blades may be utilized. The cut intraocular lens may have one continuous cut or be cut into multiple smaller pieces. The single cutting step may apply balanced forces and torque to avoid damaging the surrounding eye anatomy, reducing the risk of trauma.
PLATE HAPTIC SULCUS INTRAOCULAR LENS WITH IMPROVED OPHTHALMIC VISCOSURGICAL DEVICE EVACUATION
The present disclosure describes a plate haptic sulcus intraocular lens (IOL) or implantable contact lens (ICL) comprising an optic and a haptic component and at least one open channel for improved evacuation of Ophthalmic Viscosurgical Device (OVD).
POLYMERIC COMPOSITION EXHIBITING NANOGRADIENT OF REFRACTIVE INDEX
Ionized radiation-absorbed, dose sensitive, highly flexible polymeric compositions are provided that exhibits multidirectional changes in refractive index. Also provided are methods of producing a precision multi-directional nanogradient of refractive index in a polymeric composition.
VARIABLE STRENGTH INTRAOCULAR LENS AND METHOD OF USING SAME
The present disclosure provides intraocular artificial lenses having a variable optical strength and methods of treating an eye disorder, such as presbyopia, using same. In some embodiments, the intraocular artificial lens comprises two optical elements that are moveable along the optical axis in relation to each other, for example in response to the accommodative process of the eye.
