FIELD: medicine.

SUBSTANCE: invention concerns medicine, and specifically ophthalmosurgery. An intraocular lens (IOL) an optical and support part. The centre of front surface the optical part represents a segment of surface derived from rotation of 4^th order Cartesian oval around the symmetry axis aligned with the IOL optical axis. The periphery of front surface of the optical part is shaped as executed in the form of a segment of ellipsoidal surfaces. The optical centre of the front surface is aligned with the IOL symmetry centre. The back surface of the optical part is flat. The support part comprises a flat disk.
