Abstract
The intraocular lens has parallel endface and side holes and is connected to two identical asymmetrical flexible elements which have two parallel straight end parts inserted in the side holes, each element is composed of two end connection and one centre supporting sectors. The supporting sector should consist of an expansion (5) and support curve (6), the expansion enclosing an arc of radius 0.3-0.9 cm and the curve shaped to produce an envelope circumference (7) of radius (R) equal to that of the support surface of the eye itself. The circumference (7) should be intersected by the concentric periphery of the lens body (1) of circumference (8) so that their two tangents through the intercept form angle alpha between 1.5 and 7.5 deg. The connection sectors (9) of the elements should have identical flexibility. Pref. the support curve (6) comprises an arc with radius (R) equal to that of the support surface of the eye, or the curve can be wave-shaped with two convex and two concave parts. Preferably the connection sectors are identically shaped with an arc joined one end to the support sector and the other end to the straight end of the element (4), both straight ends lying in the same quadrant.
