ABSTRACT:
A posterior chamber lens implant 10 formed of a soft material comprises a lens 12, a pair of flexible and resilient holding arms 14, 16 formed integrally with and projecting from the periphery of the lens 12 and lying in substantially the same plane as the lens 12, each arm 14, 16 having a first end 22 formed integrally with the lens 12 and a second end 24 distanced from the periphery of the lens 12, and a flexible web 18, 20 associated with each arm 14, 16 each web 18, 20 stretching between and being formed integrally with the periphery of the lens 12 and the second end 24 of its associated arm 14, 16. The webs 18, 20 are designed to hold the arms 14, 16 in position to prevent them flopping about during implantation and use of the lens implant 10. However, the webs 18, 20 are formed of a flexible material and thus it is possible to compress the arms 14, 16 towards the periphery of the lens 12 to assist in insertion of the lens implant 10 into the capsular bag or the ciliary sulcus of the eye.
