At this time, human knowledge are missing for this technique. Todani et al123 had been able to evaluate IOP consistently utilizing a ring-formed intraocular sensor positioned in the lens capsule of rabbit eyes for as much as twenty five months (Implandata Ophthalmic Goods GmbH, Hannover, Germany; Fig. one).
