INTRAOCULAR RING SYSTEM
A support system for an intraocular lens (IOL) comprising a primary intraocular ring (PIR) mountable to an eye and a secondary device (SD), the SD in communication with the PIR and movable relative to the PIR. The movement can be one or more of rotation, forward-backward movement, decentralization, tilt and angulation. The IOL can be controllably and non-invasively moved relative to the PIR, with the movement being one or more of rotation, forward-backward movement, decentralization, tilt and angulation.
Toric lens guide for use in conjunction with a toric intraocular lens so as to properly orient the toric lens in order to properly correct astigmatism
A tonic lens guide comprises a substantially linear bar member and a pair of crab claw members fixedly attached to opposite ends of the linear bar member. The toric lens guide is adapted to be mounted upon an intraocular lens (IOL) which has been implanted within the capsular bag of a human eye during cataract surgery such that the substantially linear bar member is adapted to be disposed atop the central optic component of the intraocular lens (IOL) while the crab claw members effectively grasp the optica/haptic junctions of the intraocular lens (IOL). After the intraocular lens (IOL) is implanted within the capsular bag, it is rotated within the capsular bag such that the substantially linear bar member of the toric lens guide will effectively define a diametrical vector across the intraocular lens (IOL) such that the cataract surgeon can precisely orient the intraocular lens (IOL) within the capsular bag such that the patient's astigmatism is optimally corrected.
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 LENSES FOR REDUCING PERIPHERAL PSEUDOPHAKIC DYSPHOTOPSIA
An intraocular lens comprising: an optic zone; and a control zone positioned peripherally relative to the optic zone and configured to reduce, minimize, and/or eliminate negative peripheral pseudophakic dysphotopsia (PPD).
Toric small aperture intraocular lens with extended depth of focus
An intraocular lens is provided that includes a refractive element and a mask. The refractive element has a first power in a first meridian and a second power greater than the first power in a second meridian. A magnitude of the first and second powers and a location of the first and second meridians are configured to correct astigmatism in a human eye. The mask is configured to block a substantial portion of light from passing through an annular region thereof and to permit a substantial portion of light to pass through a central aperture thereof to enhance an astigmatism correction rotational misplacement range and depth of focus.
Toric intraocular lens, intraocular lens insertion tool, and method for producing toric intraocular lens
There is provided a toric intraocular lens which improves the visibility of a toric axis. The toric intraocular lens is a toric intraocular lens including a lens body provided with an astigmatic axis. A mark indicating the astigmatic axis is formed at an optical surface of an outer rim portion of the lens body, and a length in a radial direction of the lens body and a length in a circumferential direction of the lens body of external dimensions of the mark are different from each other in top view of the optical surface.
INTRAOCULAR LENS THAT IMPROVES OVERALL VISION WHERE THERE IS A LOCAL LOSS OF RETINAL FUNCTION
Systems and methods are provided for improving overall vision in patients suffering from a loss of vision in a portion of the retina (e.g., loss of central vision) by providing symmetric or asymmetric optic with aspheric surface which redirects and/or focuses light incident on the eye at oblique angles onto a peripheral retinal location. The intraocular lens can include a redirection element (e.g., a prism, a diffractive element, or an optical component with a decentered GRIN profile) configured to direct incident light along a deflected optical axis and to focus an image at a location on the peripheral retina. Optical properties of the intraocular lens can be configured to improve or reduce peripheral errors at the location on the peripheral retina. One or more surfaces of the intraocular lens can be a toric surface, a higher order aspheric surface, an aspheric Zernike surface or a Biconic Zernike surface to reduce optical errors in an image produced at a peripheral retinal location by light incident at oblique angles.
INTRAOCULAR LENS DEVICE AND RELATED METHODS
An intraocular device that includes a bas member is provided. The device can be an accommodation intraocular lens device with the base member and a power changing lens. The base member comprises an annular haptic that surrounds a central cavity having an open end. The power changing lens is configured to fit within the central cavity. The haptic comprises one or more projections, e.g., tabs that hold another device in position. In the case of the accommodating intraocular lens device, the other device is the power changing lens. The base member and the power changing lens are maintained separate until assembly in the eye of the patient. During assembly, the base member is advanced into the capsular bag of a patient through a capsulorhexis and oriented such that the open end of the central cavity faces the cornea. Subsequently, the power changing lens is advanced into the central cavity through the capsulorhexis. The one or more tabs are placed anterior of the power changing lens to secure the power changing lens within the cavity.
DIFFRACTIVE INTRAOCULAR LENSES FOR EXTENDED RANGE OF VISION
Apparatuses, systems and methods for providing improved ophthalmic lenses, particularly intraocular lenses (IOLs). Exemplary diffractive intraocular implants (IOLs) can include a diffractive profile having multiple diffractive zones. The diffractive zones can include a central zone that includes one or more echelettes and a peripheral zone beyond the central zone having one or more peripheral echelettes. The central diffractive zone can work in a higher diffractive order than a remainder of the diffractive profile. The combination of the central and peripheral zones and an optional intermediate zone provides a longer depth of focus than a diffractive profile defined just by a peripheral and/or optional intermediate zone.
METHODS FOR SELECTING INTRAOCULAR LENSES AND RELAXING INCISIONS FOR CORRECTING REFRACTIVE ERROR
The disclosure provides a method for selecting toric intraocular lenses (IOL) and relaxing incision for correcting refractive error. The one or more toric IOL and relaxing incision combinations can be used for off-axis correction of refractive errors such as astigmatism. The disclosure provides a method for selecting toric IOL and relaxing incision combinations that have combined astigmatism correcting powers and off-axis positions or orientations of the astigmatism correcting axes of the toric IOL and relaxing incision that are effective to yield lower residual astigmatism than on axis correction methods. The toric IOL and relaxing incision combinations also allow the user to avoid incisions that will radially overlap with a cataract incision thereby provided improved outcomes.
