PHAKIC INTRAOCULAR LENS
The present invention is a phakic intraocular lens for implantation between an iris and a crystalline lens. The phakic intraocular lens includes a diffraction grating 5 disposed in a lens central part 2 and having circular, coaxial grooves formed thereon, and a support part 3 disposed outside the diffraction grating 5 and supporting the diffraction grating 5. A hole 6 is formed in the center of the diffraction grating 5.
METHOD OF SURGICALLY IMPLANTING AN INTRAOCULAR LENS (IOL) USING A CAPSULAR PROSTHESIS TO SUPPORT POSTERIOR CHAMBER FIXATION
A capsular prosthesis is disclosed that is implanted to support posterior chamber placement of IOLs. The capsular prosthesis can be implanted to replace the capsule in situations where the patient's natural capsule has been rendered incapable of providing the structural support necessary to maintain proper centration of an IOL implanted therein. The prosthesis is surgically implanted into the eye by inserting the prosthesis into the eye through a primary incision. The prosthesis is secured to the sclera of the eye with at least two transscleral sutures to establish at least three points of contact between the sclera and the at least three apertures of the prosthesis. The at least two transscleral sutures support the sheet within a desired plane located within the posterior chamber, the plane containing a predetermined surgical axis passing through the center aperture. The IOL is inserted through the primary incision and optically captured on the prosthesis.
Optical Implant And Methods Of Implantation
An apparatus has a central lens body for providing vision correction for a patient. The lens body has a central aperture and is configured as one of: a diffractive lens or a refractive lens. The lens body has at least one haptic extending from the lens body, and the central aperture has a form of a circular hole extending fully through the lens body when the apparatus is implanted in the eye. The lens body is formed from a substantially transparent material and the central aperture includes a darkened perimeter. The darkened perimeter of the central aperture includes a darkened internal wall extending through the lens body from an anterior surface to a posterior surface of the lens body.
Intraocular lens for implantation in a ciliary sulcus of an eye
A foldable intraocular lens, made from a foldable soft material, for implantation in a ciliary sulcus of an eye having an iris, is provided with an optically active lens part having an optical axis and at least four haptics unitary with the optically active lens part and uniformly spaced about a periphery of the optically active lens part. The optically active lens part having a non-convex rim between any two neighboring haptics being free from surface irregularities that interfere with the iris. Each haptic comprising a closed loop, and a shoulder connecting the loop with the optically active lens part, the haptic loops being elastically deformable in a plane perpendicular to the optical axis of the optically active lens part in a direction toward the optically active lens part.
INTRAOCULAR LENS HAVING A SPECIFIC, THREE-DIMENSIONALLY CURVED HAPTIC ELEMENT
An intraocular lens is provided which includes a single optical part, a haptic element, which is coupled to the optical part, and an optical main axis, which penetrates a front face and a rear face of the optical part, the haptic element having a first haptic part, which is in the form of a first ring and extends around the optical part, and at least one second haptic part, which is in the form of a second ring and extends around the optical part and is elastically movable relative to the first haptic part, at least one of the two rings being uneven in the peripheral direction about the optical main axis, at least one of the two rings having exactly two ring valleys and exactly two ring hills.
Exchangeable optics and therapeutics
An exchangeable optics system includes an intraocular base that can be fixed within an eye. The intraocular base includes one or more couplers and a supporting structure. The one or more couplers releasably couple to an exchangeable optic or therapeutic and can include magnetic material. The supporting structure can include haptics and a main structure that physically supports the exchangeable optic or the therapeutic that is coupled via the one or more couplers. In some cases, the intraocular base can include a fixed lens within or on the main structure. The exchangeable optic can include corresponding one or more couplers, which may be formed of magnetic material. The therapeutic can be in the form of a magnetic particle.
Intraocular Lens Combination for Restoration of Refraction and Accommodation
An intraocular lens combination of independent lens constructions includes a first lens construction for restoration of refraction of the aphakic eye and a second lens construction for restoration of accommodation of the phakic eye. The preferred embodiment of the first lens construction includes a lens of fixed optical power implanted in the capsular bag and second lens construction including an accommodative lens of variable optical power implanted in front of the bag. The intraocular lens combination can include corrective optics to correct for both fixed and variable residual optical errors.
Intraocular Refractive Phakic Lens and Method
Described is a refractive phakic lens that has haptics extending away from the optical portion and in which the haptics have a compressible and release portion in the form of reversed undulation shape and at the end of the reversed undulation is a haptic pad that contacts the sulcus. Also, there is a rim structure on the posterior surface of the optic member which extend circumferentially but has interruption. Also, there is an opening at the optical axis of the lens member. Thereby fluid can flow through the opening and through the interruptions.
INTRAOCULAR LENS INCLUDING SILICONE OIL
An intraocular lens (IOL) having an optical axis extending in an anterior-posterior direction and an equator extending in a plane substantially perpendicular to the optical axis is described. The IOL includes: an elastic anterior face located anterior to the equator; a posterior face located posterior to the equator, wherein the anterior face, the posterior face, or both comprises a poly(dimethylsiloxane) elastomer having a durometer between about 20 Shore A to about 50 Shore A; and a chamber located between the anterior face and the posterior face comprising a silicone oil comprising polysiloxanes comprising diphenyl siloxane and dimethyl siloxane units, the silicone oil having a maximum viscosity of about 800 cSt at 25° C.
METHOD OF IMPLANTING AN INTRAOCULAR OPTIC ASSEMBLY
A method of implanting an intraocular optic assembly that has at least a first and second optics interconnected to one another with a plurality of stanchions can include rotating the first optic and the second optic relative to one another and thereby drawing the stanchions at least one of between the first optic and the second optic and around one of the first optic and the second optic.
