Abstract: A system for easily transferring an intraocular lens (IOL) from an inserter into a patient's eye. The system includes an inserter handpiece with a holding station for receiving or storing an IOL. The IOL may be pre-loaded within the holding station during manufacture, and the inserter handpiece coupled to a delivery tube so that the entire system is ready for use by a surgeon to implant an IOL. The IOL may have an optic and leading and trailing haptics coupled to the optic, and the holding station may be capable of manipulating the haptics as desired to facilitate transfer of the IOL through the delivery tube into the eye. For instance, the holding station may fold one or both of the haptics over the optic. Preferably, the holding station maintains the haptics in their folded positions during transfer of the IOL into the delivery tube. The holding station desirably maintains the IOL in a relaxed configuration during storage.

Abstract: Apparatus, and methods of making and using apparatus, for inserting intraocular lenses (IOLs) are disclosed. The apparatus includes a hollow tube having an interior wall defining a hollow space through which an intraocular lens may be passed from the open space into an eye.

Abstract: A container for disinfecting and storing a contact lens comprising a container having a nonporous but oxygen-permeable, water-impermeable liner that forms a continuous barrier layer to allow oxygen to escape but prevent water from escaping when the container becomes pressurized, such as when an oxidative disinfectant is neutralized catalytically to generate free oxygen (O2). A rigid shell against which the liner is disposed is porous to oxygen and includes a main body and a cap removably attachable to an upper rim of the main body. The container also may have a lens holder for supporting a contact lens. The liner may be on the inside of the shell, or vice versa. The liner may be on the inside of the cap which has openings through which the liner expands when the container becomes pressurized as an indicator that the disinfecting process is underway.

Abstract: A device for inserting an intraocular lens (IOL) into an eye includes a tubular body member with an inner surface and a plunger with an gripping device that is receivable within the body member. The gripping device includes a locking member and is configured such that when urged longitudinally in a distal direction, the gripping device is movable in the distal direction within the body member. However, when urged longitudinally in a proximal direction, the gripping device is prevented from moving in the proximal direction by the locking member engaging with the inner surface of the body member. As such, inadvertent movement of the plunger in the proximal direction caused by pulling back on the plunger is substantially prevented. If proximal movement of the plunger is desired, then the plunger may include handle that is operatively coupled to the gripping device such rotation of the handle causes the handle to move longitudinally in the body member.

Abstract: Treating glaucoma utiilizing a shunt having an elastormeric plate and a non-valved elastomeric drainage tube. The plate is positioned over a sclera with an outflow end of the elastomeric drainage tube open to an outer surface of the plate. An inflow end of the drainage tube tunnels through the sclera and cornea to the anterior chamber of the eye. The drainage tube collapses upon initial insertion within an incision in the sclera and cornea, or at a kink on the outside of the incision, but has sufficient resiliency to restore its patency over time. The effect is a flow restrictor that regulates outflow from the eye until a bleb forms around the plate. The plate desirably has a peripheral ridge and a large number of fenestrations, and a longer suturing tab extending from one side of the plate to enhance visibility and accessibility when suturing the shunt to the sclera.

Abstract: Devices, systems, and methods for treatment of an eye alter aspiration flow from the eye in response to an occlusion of the aspiration conduit pathway. Where aspiration is drawn from the eye using a volumetric pump, the pump can be reversed so as to induce fluid reflux from the aspiration conduit pathway into the eye to help clear the occlusion. The pump may vary the reverse flow in response to sensed aspiration pressure or the like, and the reverse flow may be halted before the pressure within the aspiration conduit pathway adjacent the eye significantly exceeds the irrigation fluid pressure and/or the pressure within the eye. Reflux may alternatively be generated by modulating a vent valve disposed between an irrigation conduit pathway and the aspiration conduit pathway.
