FIELD: medicine; ophthalmology.
SUBSTANCE: intraocular lens of eye (ILE) contains haptic and optical part including spherical surface. The forward surface of optical part contains two surfaces. The first surface is executed in the form of segment of the convex spherical surface turned by camber towards a cornea. The axis of symmetry of spherical surface coincides with the main axis of symmetry of artificial lens of eye. The second surface is executed in the form of ellipsoidal segment bent three-axis ellipsoidal surface turned by concavity 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 segment are executed on the haptic part. Back surface optical and haptic part are executed flat.
EFFECT: presbyopy correction in combination with difficult myopic astigmatism, expansion of arsenal of ILE.
