Exocapsular device and method for lens stabilization
A device for implantation into an eye for supporting an intraocular lens during and following surgery. The device may include a ring and at least one support. The ring may have an open portion defined between a first eyelet on a first end and a second eyelet on a second end, the ring being radially compressible. The at least one support may be defined internally of the ring and have a position on which a lens is nestably engaged with the at least one support above a tear in the capsular bag of the eye.
1. A device for implantation into an eye, comprising:
a ring having an open portion defined between a first end and a second end, the ring being radially compressible;
at least one support defined internally of the perimeter of the ring and having a position for nestably engaging a lens, the at least one support being positioned above a tear in a capsular bag of the eye;
the at least one support is a chord engaged with, and extending between, a third end and a fourth end of the ring, where the third and the fourth ends lie on a circumference of the ring, and the circumference of the ring lies within a plane;
at least, one portion of the ring is circular and the at least one support chord is a straight chord.
2. The device of claim 1 , wherein the device is made of biocompatible material.
3. The device of claim 2 , wherein the biocompatible material is polymethylmethacrylate.
4. The device of claim 1 , wherein:
the ring further includes a first eyelet on the first end and a second eyelet on the second end.
5. The device of claim 1 , wherein:
the chord is adapted for providing resting support of an interior of a posterior facing side of the lens.
6. The device of claim 1 , wherein
the perimeter of the ring has the circumference and the circumference is smaller than a circumference of the lens, which is supported on the ring.
7. The device of claim 1 , wherein
a shape of the ring is not a complete round circle.
8. The device of claim 1 , wherein:
the engagement of the chord and the ring at the third end and the fourth end is curved, thereby minimizing risk of further damage to the eye.
