Abstract
A method of implanting a continuous iris-expanding ring in an eye involves ejecting the continuous iris-expanding ring from a distal end of a cannula toward an iris of the eye, securing a distal portion of the continuous iris-expanding ring device ring to the iris of the eye, and securing a proximal portion of the continuous iris-expanding ring to the iris of the eye. The continuous iris-expanding ring is in a collapsed configuration in the cannula prior to being ejected and in an expanded configuration when the proximal portion and the distal portion of the continuous iris-expanding ring are secured to the iris of the eye and extend across the pupil.
