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.
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.
INTRAOCULAR PSEUDOPHAKIC CONTACT LENS WITH MECHANISM FOR SECURING BY ANTERIOR LEAFLET OF CAPSULAR WALL AND RELATED SYSTEM AND METHOD
An apparatus includes an intraocular pseudophakic contact lens having an optical lens and haptics extending radially from the optical lens. The haptics are configured to be inserted under an anterior leaflet of a capsular wall in an eye in order to capture and confine the haptics under the anterior leaflet. Anterior surfaces of the haptics are configured to contact an inner capsular wall surface at the anterior leaflet. Posterior surfaces of the haptics include ridges configured to contact at least one edge of an artificial intraocular lens and capture the artificial intraocular lens between the ridges. The anterior surface of each haptic includes one or more divots or holes.
Ophthalmic device for drug delivery
An ophthalmic implant for drug delivery. The implant includes a primary intracapsular device coupled to a secondary device, wherein, when implanted in a patient's eye, the primary intracapsular device is held in place by the patient's capsular bag and the secondary device is held in place by the primary intracapsular device. The implant may be inserted in the eye by injecting the primary intracapsular device into the eye either before or after attaching the secondary device to the primary intracapsular device, and subsequently positioning the joined secondary device and primary intracapsular device with the primary intracapsular device held in place by the patient's capsular bag and the secondary device held in place by the primary intracapsular device. The secondary device may be designed to hold a tertiary device that can be implanted and attached at the time of surgery or anytime postoperatively.
SCLERAL FIXATION DEVICE FOR INTRAOCULAR LENS SUPPORT AND SURGICAL METHODS FOR THE INSERTION OF THE DEVICE
A scleral fixation device for intraocular lens support (Arrieta's Holder) including: a receptacle and a plurality of Arrieta's Supports from the receptacle to the sclera, and surgical methods of inserting the device.
MODULAR INTRAOCULAR LENS DESIGNS, TOOLS AND METHODS
Modular IOL systems including a base and a lens, wherein the lens includes tabs for connection to the base. The modular IOL allows for the lens to be adjusted or exchanged while leaving the base in place, either intra-operatively or post-operatively.
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.
PROSTHETIC CAPSULAR DEVICES, SYSTEMS, AND METHODS
A prosthetic capsular device configured to be inserted in an eye after removal of a lens, in some embodiments, can comprise a housing structure comprising capable of containing an intraocular device and an equiconvex refractive surface. The housing structure can comprise an anterior portion comprising an anterior opening, a posterior portion comprising a posterior opening, and a continuous lateral portion between the anterior portion and the posterior portion.
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.
IN SITU ADJUSTABLE OPTICAL MASK
Implantable corneal and intraocular implants such as a mask are provided. The mask can improve the vision of a patient, such as by being configured to increase the depth of focus of an eye of a patient. The mask can include an aperture configured to transmit along an optical axis substantially all visible incident light. The mask can further include a transition portion that surrounds at least a portion of the aperture. This portion can be configured to switch from one level of opacity to another level of opacity through the use of a controllably variable absorbance feature such as a switchable photochromic chromophore within a polymer matrix.
