摘要：
An accommodating intraocular lens (AIOL) for implantation within a capsular bag of a patient's eye comprises first and second components coupled together to define an inner fluid chamber and an outer fluid reservoir. The inner region of the AIOL provides optical power with one or more of the shaped fluid within the inner fluid chamber or the shape of the first or second components. The fluid reservoir comprises a bellows region with fold(s) extending circumferentially around an optical axis of the eye. The bellows engages the lens capsule, and a compliant fold region between inner and outer bellows portions allows the profile of the AIOL to deflect when the eye accommodates for near vision. Fluid transfers between the inner fluid chamber and the outer fluid reservoir to provide optical power changes. A third lens component coupled to the first or second component provides additional optical power.
权利要求：
1. An accommodating intraocular lens (AIOL) system for placement within a lens capsule of a subject, the AIOL system comprising: an accommodating lens unit including- a first component (4340a) having a first optical component (4310), a second component (4340b) having a second optical component (4350) posterior with respect to the first optical component (4310), a chamber (4305) between the first optical component (4310) and the second optical component (4350), and a fluid reservoir (4303) extending at least partially around the chamber (4305), wherein - the chamber (4305) and the fluid reservoir (4303) are in fluid communication and wherein, in response to forces exerted on the fluid reservoir (4303), optical fluid can flow between the fluid reservoir (4303) and the chamber (4305), and the optical fluid in the chamber (4305) and the first optical component (4340a) define an optical power that changes dynamically based on the forces exerted on the fluid reservoir (4303); and a fixed lens (4330) having a constant optical power, the fixed lens (4330) being configured to be removably coupled to the accommodating lens unit such that the fixed lens (4330) is anterior of and spaced apart from the first optical component (4340a) of the accommodating lens unit.
2. The AIOL system of claim 1 wherein the chamber (4305) has a dimension and/or shape, and wherein deflection of the first optical component (4310) in response to the forces exerted on the fluid reservoir (4303) changes the dimension and/or shape of the chamber (4305).
3. The AIOL system of claim 1 wherein deflection of the first optical component changes a separate distance between inner surfaces of the first and second optical components (4310 and 4350).
4. The AIOL system of claim 1 wherein deflection of the first optical component (4310) changes a radius of curvature of the first optical component (4310).
5. The AIOL system of claim 1 wherein the first optical component (4310) comprises a deflectable member configured to deflect from a planar shape in a neutral pressure state to a curved shape in response to fluid transfer between the chamber (4305) and the fluid reservoir (4303).
6. The AIOL system of claim 1 wherein the optical power provided by the optical fluid in the chamber (4305) in combination with a shape of the first optical component (4310) effectuate a portion of the optical power change of the AIOL system.
7. The AIOL system of claim 1 wherein the first optical component (4310) and/or the second optical component (4350) are biased to be in a configuration that provides no optical power.
8. The AIOL system of claim 1 wherein the fluid reservoir (4303) extends continuously circumferentially around the first and second optical components (4310 and 4350).
9. The AIOL system of claim 1 wherein, in response to the forces exerted on the fluid reservoir (4303), the second optical component (4350) is configured to deform less than the first optical component (4310) or not at all.
10. The AIOL system of claim 1 wherein the fixed lens (4330) is configured to be releasably attached to the first component (4340a).
11. The AIOL system of claim 1 wherein the anterior positioning of the fixed lens (4330) enables the fixed lens (4330) to be removed from the accommodating lens unit and replaced with another fixed lens while the accommodating lens unit is in situ.
12. The AIOL system of claim 1 wherein the fixed lens (4330) is configured to be snap-fit into the first component (4340a).
13. The AIOL system of claim 1 wherein the fixed lens (4330) has a first periphery of the fixed lens (4330), wherein the first component (4340a) has a second periphery, and wherein the first periphery of the fixed lens (4330) is configured to be positioned within the second periphery of the first component (4340a).
14. The AIOL system of claim 1 wherein the fixed lens is a toric lens.
15. The AIOL system of claim 1 wherein the fixed lens has a positive or negative fixed power.
