TWO-PART ACCOMMODATING INTRAOCULAR LENS DEVICE
A two-part accommodating intraocular lens (IOL) device for implantation in a capsular bag of a patient's eye. The IOL device includes a primary lens assembly and a power changing lens. The primary lens assembly includes a fixed lens and a peripherally disposed centration member. The centration member has a circumferential distal edge and a first coupling surface adjacent the circumferential distal edge. The power changing lens has an enclosed, fluid- or gel-filled lens cavity and haptic system disposed peripherally of the lens cavity. The haptic system has a peripheral engaging edge configured to contact the capsular bag and a second coupling surface. The first and second coupling surfaces are in sliding contact with one another to permit movement of the power changing lens relative to the primary lens assembly and also to maintain a spaced relationship between the fixed lens and the lens cavity during radial compression of the power changing lens.
Capsular ring with improved fixation and centering
A capsular ring includes substantially circular anterior and posterior surfaces each defining a central void of the capsular ring, at least a portion of the anterior and posterior surfaces being substantially flat. The capsular ring further includes an exterior surface extending around the circumference of the capsular ring between the anterior surface and the posterior surface, wherein there is a sharp transition between the exterior surface and both the anterior surface and the posterior surface. The capsular ring further includes a plurality of orifices spaced circumferentially around the exterior surface and a plurality of haptics spaced circumferentially around the exterior surface and extending outwardly from the capsular ring; each of the plurality of haptics being configured, upon insertion of the capsular ring into a capsular bag of a patient's eye, to engage an equatorial region of the capsular bag of the patient's eye.
COSMETIC CORNEAL INLAY AND IMPLANTATION METHOD THEREOF
Disclosed is an intrastromal insert, already preformed, of solid, transparent, impermeable, biocompatible, physiologically inert and chemically resistant material, with notches allowing the passage of metabolites, substances, cells or portions thereof, and drugs, configured to receive printing, which is adapted in the space of the corneal stroma to change the eye color and/or to solve the problem of insufficient pigmentation of the iris. The method and the related component to change, permanently and reversibly, the eye color for aesthetic purposes are described as well.
Asymmetric capsular ring for inhibiting capsular opacification
A capsular ring for insertion into a capsular bag of a patient's eye includes an anterior ring defining a first opening and having a first cross-sectional width and a posterior ring defining a second opening and having a second cross-sectional width. A diameter of the first opening is greater than a diameter of the second opening, and the second cross-sectional width is greater that the first cross-sectional width. The capsular ring further includes a sidewall connecting the first ring and the second ring, the sidewall comprising a plurality of orifices spaced circumferentially around the sidewall.
Intraocular assembly
An intraocular assembly includes a peripheral side wall (12) that has a rim (16) sized to receive therein an intraocular device, and a posterior peripheral edge (20) that is sharp and extends out from a posteriorly-facing end face (22) of the side wall. An interior perimeter of the rim is a combination of continuous concave and convex shapes.
Intraocular Lens Assembly
An intraocular lens assembly is used in cataract surgery. An intraocular lens assembly (100) has a haptic (102) having a ring (106), a plurality of arcuate arms (108), and a plurality of haptic arm bases (110). Each of the arms (108) is connected with the ring (106) by a respective base (110). An optic (104) has at least two pairs of opposed holes (112). The holes (112) are positioned in the close proximity with an outer peripheral edge of the optic (104). The optic (104) is removably positionable in the haptic (102) by a snap fit lock forming the intraocular lens assembly. The intraocular lens assembly (100) has a first unlocked position wherein haptic (102) is dissembled from the optic (104), and a second locked position wherein the optic (104) is snap fitted in the haptic (102).
Method of implanting and forming masked intraocular implants and lenses
Intraocular implants and methods of making intraocular implants are provided. The intraocular implants can improve the vision of a patient, such as by increasing the depth of focus of an eye of a patient. In particular, the intraocular implants can include a mask having an annular portion with a relatively low visible light transmission surrounding a relatively high transmission central portion such as a clear lens or aperture. This construct is adapted to provide an annular mask with a small aperture for light to pass through to the retina to increase depth of focus. The intraocular implant may have an optical power for refractive correction. The intraocular implant may be implanted in any location along the optical pathway in the eye, e.g., as an implant in the anterior or posterior chamber.
INTRAOCULAR IMPLANTS AND RELATED KITS AND METHODS
Devices, methods and kits are described for reducing intraocular pressure. The devices include a support that is implantable within Schlemm's canal and that may restore or maintain at least partial patency of the canal without substantially interfering with transmural or transluminal fluid flow across the canal. The devices utilize the natural drainage process of the eye and may be implanted with minimal trauma to the eye. Kits may include a support and an introducer for implanting the support within Schlemm's canal. Methods may include implanting a support within Schlemm's canal, where the support is capable of restoring or maintaining at least partial patency of the canal without substantial interference with transmural or transluminal fluid flow across the canal.
Scleral lens with fenestration and pockets
The present invention provides a scleral lens with a fenestration and pockets. One fenestration or a plurality of annularly-distributed fenestrations are provided in an optic zone of the scleral lens; and two or more pockets are provided in a pocket annular zone on a posterior surface of the optic zone. The pockets are configured to trap gas bubbles near the fenestration, where the fenestration is located radially outward from the pocket annular zone and not located in a transition zone of the scleral lens, and the transition zone is configured to be located above the limbus of the eyeball during wearing of the scleral lens. The lens of the present invention will not be adsorbed to the cornea, and can be worn comfortably and maintain clear visual acuity for up to 12 hours.
