Intracapsular pseudophakic device
View Patent ↗Intraocular devices for use in and attached to the natural lens capsule of an eye are provided. The lens capsule may be maintained in a configuration to avoid post-operative changes that are deleterious to vision. Single or dual optic systems are provided, which may be accommodating. Combinations of devices to obtain dual optic systems are disclosed.
1. A device to be placed in an anterior capsule opening of an eye, the anterior capsule opening having a periphery, comprising:
a ring and a membrane therewithin, the ring being adapted to form a sealing area between the ring and a surface of the anterior capsule, the sealing area configured for fluid communication with a conduit extending outside the capsule; and
the ring having a flow channel, said flow channel having a port connected and a port thereto whereby when the ring contacts the posterior surface of the anterior capsule of the eye, reduced pressure may be applied in the flow channel which pulls a portion of the anterior capsule into the flow channel thereby securing the membrane.
2. A dual optic lens system for an eye comprising:
a first optic adapted to be located within the lens capsule adjacent a posterior portion thereof,
a second optic adapted to be positioned within an opening in an anterior portion of the lens capsule,
means for securing the second optic within the opening, and
the means for securing the second optic within the opening comprises a ring attached to the optic and having a flow channel, said flow channel having a port connected thereto, whereby when the ring contacts a posterior surface of the anterior capsule of the eye, reduced pressure may be applied in the flow channel which pulls a portion of the anterior capsule into the flow channel thereby securing the optic.
3. A device to be placed in an anterior capsule opening of an eye, the anterior capsule opening having a periphery, comprising:
a ring and a membrane therewithin, the ring being adapted to form a sealing area between the ring and a surface of the anterior capsule, the sealing area configured for fluid communication with a conduit extending outside the capsule;
said membrane including an optic within the ring; and
the ring having a flow channel, said flow channel having a port connected thereto, whereby when the ring contacts a posterior surface of the anterior capsule of the eye, reduced pressure may be applied in the flow channel which pulls a portion of the anterior capsule into the flow channel thereby securing the membrane.
