Abstract
A device for use in a surgical procedure on an eye of a living being, includes a retraction member, destined for insertion into the anterior chamber of the eye. The retraction member has a hook-shaped engagement part for retracting the iris, whereby at least the engagement part of the retraction member is made of a deformable material with shape memory. Thus, the retraction member is insertable into the anterior chamber with the engagement part exhibiting 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.
