（25）亂視手術の家兎に於ける量定實験

Quantitative investigation of the operation to astigmatismus in rabbits

　乱視に対する佐藤氏の角膜後面切開手術は既に人眼にも施行されて居るが私は手術手技の平易な亦手術に依る偶発症の出来るだけ少い，而も手術時に於ける量定が可能であればと考へ，「田川式RK-D型電気メス」に自家考按（渡辺）の量定用凝固針（銀製）を用いて乱視手術の量定実験を行つたので報告する。

Using six kinds of coaggulation needles made by ourselves 3.0mm, 5.0mm and 7.0mm long (diametre 1.5mm and 0.5mm), the operation to astigmatismus in 20 rabbits was quanti-iatively investigated.

Expected results were not achieved. It may be advisable to use a fine needle in such operation. Electric needle used in these investigations is Tagawa's RKD Type electric knife.
