FIELD: medicine.

SUBSTANCE: invention relates to fields of medicine and medical equipment, namely to field of ophthalmic surgery and is intended for correction of aphakia after extracapsular cataract extraction. Elastic intraocular lens contains optic part, inside which light-diffusing diaphragm is placed. Diaphragm is made in form of ring, whose external diameter coincides with diameter of optic part, internal diameter constituting 0.5-1.5 mm. Light-transmitting ability of peripheral part of diaphragm is by 40-60% lower than light-transmitting ability of transparent zone.

EFFECT: application of the invention will make it possible to reduce spherical aberrations in eye optic system considerably and at the same time considerably increase definition depth.
