ARTIFICIAL EYE LENS POSSESSING DOSED INTRAOCULAR FOCAL POWER CHANGES

摘要

FIELD: medical engineering. ^ SUBSTANCE: device has ring-shaped haptic part having two external diametrically opposite projections in its principal plane manufactured as a whole with it as flat spirals bent to the same side and the optical part. The optical part has single or two lenses. The haptic part has three internal ring-shaped grooves forming ring-shaped projections. Through opposite slits are available on the second and the third frontal projection relative to cornea. The slits are congruent to projections of each lens and serve as means for placing a lens on one of the ring-shaped projections. The internal ring-shaped grooves allow the lens projections to move in them. The through slits on the frontal and the third ring-shaped projections are arranged one under the other. The through slits on the second ring-shaped projection are arranged between those three through slits. Non-penetrating opposite holes are available in peripheral part of the frontal surfaces each of the lenses to enable lens rotation by moving their projection members in the ring-shaped groove of the haptic part. ^ EFFECT: reduced risk of traumatic complications. ^ 3 cl, 7 dwg
