A method and apparatus for performing eye surgery. A deformable body having shape memory retentive properties is formed with one or more open loops. The body is longitudinally stretched so that it can follow a needle through a small caliber needle track formed in the cornea, into the anterior chamber in front of the iris. There, the body has relaxed and reverted to its original shape. The needle is of such size that the needle track self-closes and no closure stitch is needed. Two sutures are connected to opposite ends of the body and one of the sutures connects the body to the needle. After the body is in the pupil of the iris, the loop openings face the wall of the iris and then the sutures are pulled to displace the body and press it against the wall of the iris to dilate the pupil.
