ABSTRACT:
An intra-ocular lens can be implanted as a posterior chamber lens by way of its lens body in a capsule sack remaining in the eye after an extracapsular operation. An equatorial edge of the lens body has a surrounding concave profile which is open to the outside and is bounded by two profile edges. At least one of the profile edges acts as a mechanical barrier against fibrosis on the rear capsule.
