  • Publication number: 20240074900
    Abstract: Described herein are devices and methods for treating eye conditions. Described is an ocular implant including an elongate member having an internal lumen forming a flow pathway, at least one inflow port communicating with the flow pathway, and at least one outflow port communicating with the flow pathway. The elongate member is adapted to be positioned in the eye such that at least one inflow port communicates with the anterior chamber, at least one outflow port communicates with the suprachoroidal space to provide a fluid pathway between the anterior chamber and the suprachoroidal space when the elongate member is implanted in the eye. The elongate member has a wall material imparting a stiffness to the elongate member. The stiffness is selected such that after implantation the elongate member deforms eye tissue surrounding the suprachoroidal space forming a tented volume.

  • Patent number: 11826246
    Abstract: An accommodating intraocular lens (IOL) can be implanted either alone or as part of a two-part lens assembly. The IOL comprises an optic, a flexible membrane and a peripheral edge coupling the optic and the flexible membrane. The peripheral edge comprises an external circumferential surface having a height and a force transmitting area defined along a portion of the height of the external circumferential surface. A closed volume spaces apart the optic and the flexible membrane. The optic is axially displaced and the flexible membrane changes in curvature about a central axis when a radial compressive force is applied to the force transmitting area. A volume defined by the closed volume remains fixed when the optic is axially displaced and the flexible membrane changes in curvature and/or when the radial compressive force is applied to the force transmitting area.

  • Patent number: 11771552
    Abstract: 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.

  • Publication number: 20230134014
    Abstract: 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.

  • Publication number: 20230081362
    Abstract: An accommodating intraocular lens device is provided. The accommodating intraocular lens device comprises a base assembly and a power lens. The base assembly comprises a first open end, a second end coupled to a base lens, and a haptic surrounding a central cavity. The haptic may comprise an outer periphery, an inner surface and a height between a first edge and a second edge. The power lens is configured to fit within the central cavity. The power lens may comprise a first side, a second side, a peripheral edge coupling the first and second sides, and a closed cavity configured to house a fluid. The first side of the power lens may be positioned at a predetermined distance from the first edge of the haptic.

  • Publication number: 20230079479
    Abstract: 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.

  • Publication number: 20230044397
    Abstract: An intraocular device that includes a fluid lens is provided. The fluid lens has an anterior side and posterior side that can be coupled together to form a closed cavity therebetween that can be filled with a liquid material. A channel can be formed in the posterior side that is configured to receive a joining substance that bonds the anterior side to the posterior side and inhibit the unintended spread of the joining substance. A syringe can be extended through a port in the fluid lens to flow liquid material into the closed cavity. Subsequently, a plug can be inserted into the port to prevent the escape of the liquid material.

  • Publication number: 20220380552
    Abstract: A halosilicone oil in the form of an uncrosslinked terpolymer represented by the following Formula (I): is disclosed, wherein at least one block forming component includes a halogenated, preferably fluorinated, substituent such as 2,2,2-trifluoroethyl or 3,3,3-trifluoropropyl. In some implementations, at least one block forming component also includes an aryl group, such as phenyl, that raises the refractive index of the polymer. In some implementations, the halosilicone oil is incorporated into an intraocular lens.
