Abstract
An anterior chamber intraocular lens implant which is donut-shaped and lacks refractive power in the portion covering the pupil of the eye. The lens includes a circular joint, or hinge, and locking latch for pivoting the two members forming the implant from a first, open position to a second, closed position. Additionally, minute, soft circular haptics are provided for keeping the lens flexible and in position and which allow only those spots to touch the angle structures of the eye. This lens is made of several basic colors that will give the appearance of a different color to an individuals iris.
Claims7
An intraocular implant for placement in the anterior chamber of the eye comprising:
- a) first and second semicircular members;
- b) movable connection means for connecting said first and second semicircular members to each other for pivoting from a first, open position for facilitating implantation into the anterior chamber of an eye to a second, closed position forming a substantially circular optic;
- c) a plurality of haptics formed integrally with said first and second semicircular members;
- and
- d) a retaining means for retaining said first and second semicircular members in said second, closed position after implantation in the anterior chamber.
A method for implantation of an intraocular implant comprising the steps of:
- a) preparing an eye to receive an intraocular implant;
- b) constructing said implant with:
- i) movable connection means for connecting first and second semicircular members to each other for pivoting from a first, open position for facilitating implantation into the anterior chamber of an eye to a second, closed position forming a substantially circular implant;
- ii) a plurality of haptics formed integrally with said first and second semicircular members;
- and
- iii) a retaining means for retaining said first and second semicircular members in said second, closed position after implantation in the anterior chamber.
- c) forming the intraocular implant in a closed-scissors configuration;
- d) inserting the intraocular implant into the eye;
- e) opening the intraocular implant;
- f) selecting an appropriate diameter to suit the eye;
- g) engaging the retaining means at the selected diameter;
- h) securing the intraocular implant in place within the eye;
- and
- i) closing the eye where the intraocular implant was inserted.
