INTRAOCULAR LENS IMPLANT Russian patent published in 2009 - IPC A61F2/14 

FIELD: medicine.

SUBSTANCE: invention refers to ophthalmology. An intraocular lens (IOL) contains an optical part and bearing supports bent towards a front face of the optical part at an acute angle to its principal plane. The front face of the optical part is concave, while its back face is convex. There are four identical bearing supports comprising curvilinear figures of the thickness decreasing to periphery and located radially, in pairs and symmetrically relative to the principal axis of the optical part. One lateral face of each bearing support lies rectilinearly and in parallel to the longitudinal axis of the bearing support. The angle between the longitudinal axes of two bearing supports in each pair with straight lateral facing each other is 60-70 degrees. The periphery of each bearing support lies on a circular arc concentric with the optical part. The other lateral face is bent, and starting from the periphery it is convex, and further to the optical part is bent. Interfaces of all the areas of the bearing support are chamfered. Each bearing support is notched starting from the interface of the optical part and bearing support and shaped the same way. The IOL is integral to be bent relative eto the principal axis.

EFFECT: application of the present IOL allows implanting it through a minute incision that reduces operative injuries and risk of postoperative complications.
