Abstract
A posterior chamber implantable intraocular lens having haptics and additional attachment structure of a discontinuous or semi-discontinuous form associated with the haptics. The posterior chamber implantable intraocular lens can be implanted using conventional techniques if the posterior chamber is determined to be suitable and adequate for implantation using conventional techniques, or can be implanted utilizing the additional attachment structure if the posterior chamber is determined to be unsuitable and inadequate for implantation using conventional techniques.
Claims50
A posterior chamber implantable intraocular lens comprising:
- a. an optical lens, the optical lens having a periphery;
- b. diametrically opposed haptics extending from the periphery of the optical lens;
- and,
- c. attachment structure associated with the diametrically opposed haptics.
A posterior chamber implantable intraocular lens comprising:
- a. an optical lens, the optical lens having a periphery;
- b. diametrically opposed haptics extending from the periphery of the optical lens;
- and,
- c. discontinuous attachment structure associated with the haptics in the form of opposed engagement fixtures extending from the periphery of the optical lens, the opposed engagement fixtures allowing for attachment of posterior iris tissue through enclavement.
A posterior chamber implantable intraocular lens comprising:
- a. an optical lens, the optical lens having a periphery;
- b. diametrically opposed haptics extending from the periphery of the optical lens, each of the haptics having an extended portion terminating in an outward end;
- and,
- c. projections extending from the periphery of the optical lens, each of the projections having an end, each end being located near an outward end of an extended portion of a haptic and defining a gap therewith, and wherein the diametrically opposed haptics including the extended portions with outward ends together with the projections define a pair of opposed and elongated engagement fixtures.
A method of installing a posterior chamber implantable intraocular lens in a posterior chamber posterior to iris tissue, the method comprising the steps of:
- a. providing a posterior chamber implantable intraocular lens, the posterior chamber implantable intraocular lens including an optical lens having a periphery, diametrically opposed haptics extending from the periphery, and attachment structure associated with each haptic;
- b. determining the suitability and adequacy of the posterior chamber for conventional implantation;
- and,
- c. installing the provided posterior chamber implantable intraocular lens in the posterior chamber by conventional implantation if the step of determining reveals the posterior chamber to be suitable and adequate for conventional implantation, or installing the provided posterior chamber implantable intraocular lens in the posterior chamber by attaching it to posterior iris tissue using the attachment structure if the step of determining reveals the posterior chamber to be unsuitable and inadequate for conventional implantation.
