ARTIFICIAL EYE LENS Russian patent published in 2008 - IPC A61F2/14 

FIELD: medicine.

SUBSTANCE: artificial lens of an eye contains a haptic and an optical part including a spherical surface. The optical part consists of one component which forward surface contains two surfaces. The first surface is executed in the form of a segment of the convex spherical surface turned by camber towards the cornea. The axis of symmetry of the spherical surface coincides with the main axis of symmetry of an artificial lens of an eye. The second surface of the component is executed in the form of the ellipsoidal segment of the convex three-axis ellipsoidal surface turned by camber towards a cornea. The marking elements in the form of the rectilinear lines which direction coincides with a direction of the big axis of an elliptic segmentare executed on the haptic part. The back surface of the optical and haptic parts is executed flat.

EFFECT: allows to provide presbyopy correction in combination with difficult hypermetropic astigmatism, and also to dilate an arsenal of artificial lenses of an eye.
