Abstract
An instrument for subretinal implantation comprising an elongate tube having a distal end and a proximal end, the tube having a lumen passing from the proximal end to the distal end, the distal end having a distal tip, wherein the lumen forms an opening in the tip, the instrument further including a plunger, the plunger being capable of sliding motion within and with respect to the tube, wherein the outer diameter of the distal end of the elongate tube is sufficiently small to be inserted through the pars plana area of an eye and the length of the distal end of the elongate tube is sufficient long to permit the opening in said tip to thereafter be inserted beneath the retina through an opening therein, wherein the plunger can express material within the lumen therefrom through the opening in the tip into the subretinal space of an eye into which the tip is inserted.
