Abstract
An intraocular lens designed for ease of insertion and for minimizing contact with intraocular tissues comprises a lens body having an optical axis, two optical surfaces and a periphery to which is fixed at least one filamentous haptic extending circumferentially and radially from the point of attachment along a curvilinear path in space to a maximum distance from the optical axis. The haptic has a proximal segment adjacent to the attachment point, a medial segment attached to and continuous with the proximal segment and a distal segment attached to and continuous with the medial segment. At least a part of the distal segment lies at the maximum distance from said optical axis and constitutes the tissue-contacting portion of the haptic. The tissue-contacting element is tangent to a second plane parallel to the first plane and displaced from it along the optical axis, and at least the medial segment of the haptic traverses a path concave toward the first plane and avoiding intersection with the second plane.
