FIELD: medicine.
SUBSTANCE: invention relates to medical equipment. Ophthalmological device contains ophthalmological lens with front and back surfaces; and one or some haptic elements, connected to ophthalmological lens. One of either back or front surfaces is made of such a shape that ophthalmological lens is configured as aspherical lens. One of back or front surface is made of such a shape that ophthalmological lens is configured as toroidal lens. Ophthalmological lens has selected edge thickness on 45-degree meridian within the range from 0.2 and 0.3 mm, and is periodically changed on toroidal lens. Edge thickness is changed in sinusoidal way.
EFFECT: application of invention makes it possible to better restore vision in some range of distance to subject without its worsening in any part - of this range.
