Abstract
A pupil expander is formed from a frame of shape-memory material with a covering made of elastomer. The frame is in the form of two arc-shaped sections connected together at one end to form a broken circle having free distal ends. Each arc-shaped section has an upper frame portion and a lower frame portion connected to each other at the distal ends thereof. The covering is disposed over each arc-shaped section and has a C-shaped cross section so as to form an outwardly facing groove between the upper frame portion and the lower frame portion. The pupil expander is configured to be folded in half with the grooves facing each other and straightened so as to form a cylindrical body for insertion into a tubular applicator and upon release from the applicator, the pupil expander resumes the shape of the broken circle to push the margins of the pupil wider.
