CAPSULAR TENSION RING, METHOD FOR MAKING A CAPSULAR TENSION RING AND CAPSULAR RING AND INTRAOCULAR LENS ASSEMBLY

摘要

The invention concerns a capsular tension ring implantable in the equatorial region of a capsular bag after cataract ablation comprising an open or closed annular body and including sharp edges and an axial width ranging between about 0.3 and 0.6 mm, or preferably about 0.5 mm. The annular body of the capsular tension ring, including the sharp edges, is made of a rigid material for the major part of the circumference, and comprises at least one joint made of flexible material between two segments of the annular body made of rigid material. The invention also concerns an assembly comprising a capsular tension ring and an intraocular implant of the type including a central optical part and a peripheral haptic part comprising one or several haptic elements extending radially from the optical part, the optical part having a peripheral edge with a sharp ridge on its rear surface. Such an implantable capsular tension ring is prepared by chemical modification either of the segments of the annular body made of rigid material, from a flexible material, or the joints made of rigid material from a flexible material.
