Intraocular lens system
View Patent ↗A two part lens system. The first part is a ring-like supporting component that is implanted in the capular bag following cataract surgery. The first component is a non-optical component and contains a pair of haptics for fixating the first component within the capular bag. The second component is an optical component that contains all of the corrective optical power of the lens system. The second component has a pair of tabs for locking the second component within the first component.
1. An intraocular lens system, comprising:
a) a ring-like base component having a hollow center, a plurality of haptics and a plurality of slots;
b) an optical component having a plurality of integrally formed tabs, the tabs sized and spaced to fit and lock within the slots in the base component by rotation of the tabs within the slots; and
c) a plurality of posterior circumferential rings formed on a posterior surface of the base component.
2. The lens system of claim 1 wherein the base component is opaque.
3. The lens system of claim 1 wherein the base component is stiff relative to the optical component.
4. An intraocular lens system, comprising:
a) a ring-like base component having a hollow center, a plurality of haptics and a plurality of slots, the base component being opaque;
b) an optical component having a plurality of integrally formed tabs, the optical component being soft relative to the base component and the tabs being sized and spaced to fit and lock within the slots in the base component by rotation of the tabs within the slot; and
c) a plurality of posterior circumferential rings formed on a posterior surface of the base component.
