<p>The invention concerns a device for injecting an intraocular implant in a patient's eye comprising a chamber for folding the optical part of the implant, a folding member, a cannula for injecting the folded implant into the eye, said cannula emerging at a first end of said chamber, a guiding channel emerging at the second end of said chamber, and a mobile piston mounted in said guide channel to drive the folded implant into said cannula. The piston (40) comprises a cylindrical end (44) designed to co-operate with said implant, said end comprising an end surface (50) substantially orthogonal to the length of the piston, said end surface having an opening (52) emerging in the side wall of the piston end and extending over part only of the piston diameter, said end being provided with a slot (54) extending over a length l such that, with the length of said opening, the total length is at least equal to that of the haptic branch, said slot communicating with said opening and further extending over the whole piston diameter to emerge at diametrical ends in the outer wall of the end of said piston.</p> |
