INTRAOCULAR LENS OF EYE Russian patent published in 2009 - IPC A61F2/14 

FIELD: medicine; ophthalmology.

SUBSTANCE: intraocular lens of eye (ILE) contains haptic and optical part including a spherical surface. The forward surface of an optical part contains two surfaces. The first surface is executed in the form of a segment of the concave spherical surface turned by concavity towards a cornea of a cornea. The axis of symmetry of a spherical surface coincides with the main axis of symmetry of ILE. The second surface is executed in the form of an elliptic segment bent three-axis ellipsoidal surface turned by concavity towards a cornea. On the haptic part are executed marking elements in the form of the rectilinear lines which direction coincides with a direction of the big axis of an elliptic segment. The back surface of the optical and haptic parts is executed flat.

EFFECT: presbyopy correction in a combination with difficult myopic astigmatism, expansion of potential of ILE.
