IMPLANTATION INSTRUMENT AND METHOD

摘要

The disclosure relates to a method and instrument for implanting retinal tissue into the sub-retinal space (80) of the eye. The method includes the steps of inducting a fragment of retinal tissue (120) into a tubular nozzle (110) of an instrument by retracting a mandrel (106) telescoped internally of the nozzle, incising the pars plana (70) region of the eye, incising the retina (68) of the eye to expose a sub-retinal target area, inserting the nozzle of the instrument through the incisions in the pars plana and retina of the eye, orientating an open end (118) of the nozzle over the target area of the retina, and retracting the nozzle relative to the mandrel of the instrument to deposit the tissue in the target area of the eye.
