Abstract
An iris retractor made of two slender elements operatively coupled via a joining mechanism, wherein each slender element has an iris grabbing hook located at its distal end; and a handle located at the proximal end of the slender element, wherein the joining mechanism is configured to endow the iris retractor with at least two configurations: a retracted configuration and an expanded configuration, wherein the length of each slender element is between 4 mm to 14 mm.
Claims8
A method for iris retraction, comprising:
- (a) providing an iris retractor that comprises:
- a first slender element and a second slender element, each slender element comprising:
- a proximal handle and a distal grabbing hook having a concave side, and a proximal handle, and
- a joining mechanism operatively coupling the first and second slender elements, and being configured to endow said iris retractor with at least two configurations:
- a retracted configuration and an expanded configuration, wherein, in the retracted configuration, said concave sides of said distal grabbing hooks face one another, and wherein, in the expanded configuration, said concave sides of said distal grabbing hooks face away from one another;
- (b) inserting the first and second slender elements through an incision at or near the limbus of an eye, when the iris retractor is in the retracted configuration;
- and
- (c) manipulating the proximal handles to transform the iris retractor from the retracted configuration to the expanded configuration, while grasping and retracting the iris of the eye with the distal grabbing hooks.
