BARRIER-OPTIC MEMBRANE WITH DIAPHRAGMATIC PROPERTIES Russian patent published in 2011 - IPC A61F2/14 

FIELD: medicine.

SUBSTANCE: invention relates to field of medicine. Membrane contains optic and flat haptic part in form of circle, and is made from copolymers of acryl or vinyl series. Haptic part is stained the same colour as patient's eyes, has central hole and cut, corresponding to remnants of iris. Size of iris remnants is larger than cut of haptic part with formation of zone of overlapping between haptic part and iris remnants on haptic part. Optic part is made detachable, on its contour made is side board, and longitudinal axis of optic part symmetry 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. Axis of groove symmetry is perpendicular to longitudinal axis and coincides with transversal axis of haptic part symmetry. Optic part is located in central hole of haptic part coaxially to its longitudinal axis in such a way that sections of anterior, posterior and internal cylindrical surface of haptic part, which enter the entire depth of groove, are congruent to it.

EFFECT: application of claimed membrane makes it possible to achieve maximally possible optic functions, ensures diaphragmatic and cosmetic properties.
