Abstract
An accommodating intraocular lens comprises a first lens component, a second lens component, and an adhesive between portions of the two lens components. The cured adhesive bonds the lens components to form a fluid chamber. The lens components are bonded to one another along a seam which extends circumferentially along at least a portion of the lens components. The lens components may comprise the same polymer material. The cured adhesive also comprises the polymer or a prepolymer of the polymer to provide increased strength. The polymer is hydratable such that the lens components and the cured adhesive therebetween can swell together to inhibit stresses between the lens components and the cured adhesive.
Claims17
A method of manufacturing an accommodating intraocular lens, the method comprising:
- providing a first lens component comprising a first optical portion having a central optical axis, a first haptic portion surrounding the first optical portion, a first inner mating portion between the first optical portion and the first haptic portion, and a first annular outer mating portion positioned radially outward from the first inner mating portion with respect to the central optical axis;
- providing a second lens component comprising a second optical portion having a central optical axis coincident with the central optical axis of the first optical portion, a second haptic portion surrounding the second optical portion, a second inner mating portion between the second optical portion and the second haptic portion, and a second annular outer mating portion positioned radially outward from the second inner mating portion with respect to the central optical axis;
- and
- bonding the first inner mating portion of the first lens component to the second inner mating portion of the second lens component at an inner seam and bonding the first annular outer mating portion with the second annular outer mating portion at an outer seam;
- wherein
- a reservoir between the inner seam and the outer seam defines a haptic reservoir,
- a reservoir between the first optical portion and the second optical portion defines a lens chamber in fluid communication with the haptic reservoir;
- and
- a distance between the first optical portion and the second optical portion, as measured along the central optical axis of the first optical portion, is configured to change in response to movement of fluid between the haptic reservoir and the lens chamber.
