Abstract:
1. A pupil dilator, comprising: a generally circular deformable ring member made of a flexible material configured to expand circumferentially for application of an expansile force substantially uniformly around a pupillary margin of a pupil of an eye, for dilating said pupil along an entirety of a circumference of said generally circular deformable ring member, said generally circular deformable ring member comprising opposing ends that define an expandable space therebetween; said generally circular deformable ring member configured in an uncoiled configuration to allow insertion of said generally circular deformable ring member through a single incision in said eye, and configured to unfold from said uncoiled configuration into a generally coiled configuration that conforms to a pupillary aperture of said pupil for engaging said pupillary margin of said pupil; a circumferential groove defined on an outer surface of said generally circular deformable ring member and configured to be in continuous contact with said pupillary margin of said pupil along said circumference of said generally circular deformable ring member; and one or more connector members positioned at one or more predetermined locations on one or more of said circumference of said generally circular deformable ring member and said opposing ends of said generally circular deformable ring member, each of said one or more connector members configured to engage with a surgical manipulating element that allows movement and manipulation of said generally circular deformable ring member around said pupillary margin of said pupil.
