METHOD FOR PLACING IMPLANT IN CHOROID THAT CAN LESS INVASIVELY AND SIMPLY PLACE IMPLANT IN CHOROID IN OPTIC DISC-MACULA AREA, AND TOOL FOR PLACING IMPLANT IN CHOROID
An implant is placed in the choroid in the posterior eye segment. The conjunctiva is incised, and an injection needle is inserted between the conjunctiva and the sclera. The tip of the injection needle is advanced to the vicinity of the optic disc along the surface of the sclera. After placing a vitrectomy lens over the cornea so that the eyeground can be observed, the tip of the injection needle that appears white is observed while observing the eyeground through the vitrectomy lens and pressing the sclera using the injection needle. The injection needle is moved to determine an appropriate insertion position of the implant in the vicinity of the optic disc, and is inserted diagonally into the sclera. The tip of the injection needle is advanced into the choroid, and the implant is inserted into the choroid through the tip opening formed at the tip of the injection needle.
