Provided is an ocular instillation assisting tool which, when the remaining volume of an eye drop gets low, makes it possible to apply the eye drop to eyes to the last drop while having the eyes fixed ahead, as in the case where a sufficient volume of the eye drop still remains. An ocular instillation assisting tool (100) according to the present invention is provided with an assisting tool main body (20) which can hold an eye drop container (10) at one end thereof in such a manner that a nozzle part (14) can be positioned below a container main body (11) while fixing a position at which the eye drop is to be applied by means of a cup (40), and which can support an eye drop discharge lever (30) in a rotatable manner at the other end thereof.本發明提供一種點眼藥水輔助器，即使眼藥水的殘量變少，亦可如同殘量多的狀態般以面向前方的狀態將眼藥水用到最後為止。本發明的點眼藥水輔助器(100)，係具備輔助器本體(20)，其在一端由杯罩(40)決定眼藥水之應投予之位置的狀態，使噴嘴部(14)成為比容器本體(11)還要下方的方式，固定點眼藥水容器(10)，且在另一端將眼藥水吐出用的控制桿(30)支撐成旋動自如。
