Abstract
A ring that can maintain a pupil in an extended position during an ophthalmic procedure. The ring has a plurality of loops that capture iris tissue. The ring is configured to extend the pupil when iris tissue is inserted into each loop. An ophthalmic procedure such as phacoemulsification can then be performed on the patient. The ring has a center opening that provides a wide view of the ocular chamber during the procedure.
Claims14
An ophthalmic ring sized to maintain a pupil of a subject's eye in an extended position during an ophthalmic procedure, the ring comprising:
- a strand, the strand including:
- at least three side elements;
- and
- at least three loops, each loop further including a top portion and a bottom portion,
- wherein, in the extended ring position:
- each side element of the at least three side elements connects the top portion and the bottom portion of two adjacent loops of the at least three loops to form the ring, the ring circumscribing a central opening through which a posterior chamber of the subject's eye can be accessed during the ophthalmic procedure, the central opening being disposed in a plane between the at least three side elements and the at least three loops, and
- each loop of the at least three loops defines an iris-retaining gap between the top portion and the bottom portion of the loop, the iris-retaining gap of each loop facing away from the central opening of the ring and dimensioned to receive iris tissue of the subject's eye during the ophthalmic procedure.
