ABSTRACT:
An iris retractor for use in operating on the eye of a living creature is proposed, by means of which the iris is drawn outwards for widening the pupil and is held at the outer edge, which is essentially formed by the transition from the cornea to the sclera.
The iris retractor essentially comprises a suspended part having a hook portion and a guide part and on which a platelet-like clamping part is displaceable relative to the hook portion.
