| 摘要 |
The invention concerns a monobloc intraocular lens made of a flexible material comprising a central optical part (1) and a haptic part (4) including two loops (5) in contact with the eye inner wall and, for each contact loop (5), two elements (10, 10') to be linked with the optical part (1), the lens having a symmetry with respect to two perpendicular axes (6, 8), the external surface (9) of each contact loop (5) having a convex shaped curve defining an apex (S), and two end points (E, E'). The circle (Ca) passing through the apex (S) and the two end points (E, E') has a diameter phi a not smaller than the mean diameter phi m of the ocular housing, and smaller than phi m + 1.5 mm; the apexes (S) are distant from each other by a distance D > phi a; the linking elements (10, 10') are adapted to be deformable in flexion in the lens main plane (3).
