ACCOMMODATION INTRAOCULAR LENS SYSTEM Russian patent published in 2013 - IPC A61F2/16 

Abstract RU 2501535 C2

FIELD: medicine.

SUBSTANCE: invention relates to medical equipment. An accommodation intraocular lens comprises a first lens with a first optical element with a first contact surface attached to a first peripheral ring by a first set of haptics; a second lens with a second optical element with a second contact surface attached to a second peripheral ring by a second set of haptics. The second peripheral ring has a size and shape to arrange the first peripheral ring so that the first optical element is in contact with the second contact surface with its centre on the optical axis of the first optical element changing thereby a refractive power of the lens. The first and second optical elements, the first and second peripheral rings, and the first and second sets of haptics are integrated as one. The first set of haptics displaces the first optical element towards the second optical element.

EFFECT: provided greater accommodation amplitude with minimum displacement of the lenses.
