Abstract:
A device for use in a surgical procedure on an eye of a living being, comprising a retraction member, destined for insertion into the anterior chamber of the eye, said retraction member made of a flexible filament and having a hook-shaped engagement part for retracting the iris, at least said engagement part of the retraction member being made of a deformable material with shape memory so that the retraction member is insertable into the anterior chamber with the engagement part in a substantially straight configuration, and subsequently the engagement part is able to recover its original hook-shaped configuration as a consequence of its material characteristics, to implement a retraction of the iris, wherein the engagement part of the retraction member is bendable into the straight configuration for insertion into the anterior chamber at a temperature below a temperature in the anterior chamber and recovers the hook-shaped configuration as a result of the temperature in the anterior chamber.
