BARRIER-OPTICAL MEMBRANE Russian patent published in 2010 - IPC A61F2/14 

FIELD: medicine.

SUBSTANCE: barrier membrane contains flat haptic part from elastic transparent material in form of circle with central hole. Additionally it contains detachable optic part, whose longitudinal symmetry axis coincides with optic axis. On lateral cylindrical surface of optic part on circumference, ring-shaped groove from 0.2 to 3.0 mm deep is made. Symmetry axis of groove is perpendicular to longitudinal axis and coincides with transverse axis of haptic part symmetry. Optic part is placed in central hole of haptic part coaxially with its longitudinal axis in such way that sections of anterior, posterior and internal cylindrical surface of haptic part entering the groove on its full depth, are congruent to it. On anterior surface of haptic part, at equal distance from its edge, two similar, parallel to each other grooves are made, and whole membrane is made from copolymers of acryl or vinyl row.

EFFECT: application of claimed invention will ensure fulfillment of function of optic correction of aphakia, and will stop outlet of silicon into anterior eye chamber.
