Artificial intraocular lenses comprise an optical zone portion for implanting in the posterior chamber of an eye, posts extending from said optical zone portion through the iris into the anterior chamber thereof, and retaining means for securing to the ends of the posts, whereby said posts and retaining means hold and position the artificial intraocular lenses within the eye. In some embodiments, the posts and retaining means are configured for an interengaging press fit. In another embodiment the posts are attached to the retaining means and are adapted to be secured to the optical zone portion. Instruments aiding in the implanting of the artificial intraocular lenses in the eye by press fitting the retaining means to the posts, comprise means for supporting the retaining means on the instrument, bridle means connecting the optical zone portion of the artificial intraocular lenses with the instrument, and means for drawing the posts toward the retaining means until the desired interengaging press fit therebetween is achieved. The instruments are also adapted to attach the posts of the retaining means to the lens portion in the other embodiment. The instruments are also modified to remove the retaining ring from the posts. The artificial intraocular lenses and instruments are adapted to provide an extra-ocular confirmation signal indicating that the posts are operatively engaged for holding the optical zone portion and retaining means together. Conductive portions of the optical zone portion and retaining means contact to close an electrical circuit providing the extra-ocular confirmation signal.
An artificial intraocular lens for implantation into the posterior chamber of an eye, the artificial intraocular lens comprising an optical zone portion fabricated of transparent material and shaped similar to a natural lens, and retaining means having a plurality of posts attached thereto and extending rearwardly therefrom, the ends of said posts adapted to be operatively engaged with said optical zone portion, wherein said optical zone portion may be implanted in the posterior chamber of an eye and said retaining means may be positioned in the anterior chamber of the eye with the posts protruding rearwardly from said retaining means through the iris and into the posterior chamber of the eye where said posts are operatively engaged with said optical zone portion, said retaining means and posts thereby together holding and positioning the artificial intraocular lens within the eye, and wherein the posts of said retaining means and the optical zone portion have conductive surfaces which contact upon operative engagement and which are adpated for connection into an electrical circuit providing a signal upon such contact, said signal comprising extra-ocular confirmation of the operative engagement.
An artificial intraocular lens for implantation in the posterior chamber of an eye, the artificial intraocular lens comprising an optical zone portion fabricated of transparent material and shaped similar to a natural lens, a plurality of posts attached to the optical zone portion near the periphery thereof and extending forwardly therefrom, and retaining means adapted to be operatively engaged with the ends of said posts, wherein said artificial intraocular lens may be imprinted in the posterior chamber of an eye with the posts protruding forwardly from the optical zone portion through the iris and into the anterior chamber of the eye, and wherein said retaining means may be operatively engaged with the ends of the posts in the anterior chamber of the eye, wherein said posts and retaining means together hold and position the lens within the eye and prevent the posts from pulling through the iris thereof, and wherein the posts of said retaining means and the optical zone portion have conductive surfaces which contact upon operative engagement and which are adapted for connection into an electrical circuit providing a signal upon such contact, said signal comprising extra-ocular confirmation of the operative engagement.
