Figure Lengend Snippet: Enlargement of the retinal hole and insertion of the subretinal prosthesis. (a) Diathermy was used and the hole was gradually widened by about 4.5 mm. (b) The subretinal prosthesis was inserted into the subretinal space with micro-forceps. (c) A curved directional laser probe tip was used to push the implanted prosthesis forward and adjust its position. (d) After the oil tamponade, the subretinal prosthesis was settled into its desired location. (e–g) Schematic images of manipulation of the plate using a curved laser probe in the subretinal space. A directional laser probe with a fixed fiber and movable shaft measuring 3.2 mm in height to its tip and 0.54 mm wide at the tip was used. (e,g) Press down the subretinal prosthesis with the laser probe without projection of curved fiber (black arrowhead). (f,g) After insertion of the subretinal prosthesis, the curved fiber (black arrowhead) of the laser probe was directed away (black arrow) from the actuation button in the subretinal space.

Article Snippet: To mitigate the possibility of an iatrogenic retinal tear, a curved directional laser probe tip (23-gauge directional endo ocular laser probe; synergetics USA, Inc., O'Fallon, MO, USA) with an expandable fiber or a moving shaft was applied to push the implanted prosthesis forward and adjust its position (Fig. ) (see Supplementary Video and online).
