ABSTRACT:
Intraocular lens for implantation in the posterior chamber of an eye, following extracapsular removal of the natural eye lens, including a lens assembly having an anterior surface formation and a posterior surface formation, at least a portion of the posterior surface formation constituting a planar contact region adapted to be seated against the adjacent planar tissue surface of the posterior capsule to form a connection interface for permanent anchoring of the lens assembly thereat, the contact region being provided with a roughened surface area defined by a series of ordered narrow linear depressions therein extending generally transversely of the plane of the contact region, for accelerated adhesion of the tissue of the adjacent posterior capsule part to the depressions and enhanced anchoring of the lens assembly to the posterior capsule part, to prevent dislodgment of the implanted intraocular lens.
