Pupillary extension can be operated safely and reliably with these two hooks.

In such cases as microcoria or IFIS, pupillary extended operation is required during surgery. Any unreasonable operation may harm pupillary margin, iris, or angle to lead to hyphemia.　In order to prevent such situations and for smooth insertion ①TOME1hook and ②TOME2 push hook are developed. By using two hooks like in the video, it is possible to prevent tissue damage and decrease post operative inflammation.
TOME 1 hook can be used for the operation of taking the ring out of the injector or attaching it to iris. The top is processed in a round shape to prevent damages of iris and anterior capsule of lens. It can also be used for nucleus treatment or adjusting the location of intraocular lens.
TOME 2 push hook is used for the insertion at twelve o’clock. It is designed, when the ring is pushed to control the ring location without sliding, and after insertion, to take off naturally without any damage for iris, if this instrument is pulled out straight.
Basically, two hooks are operated shrinking the ring like a diamond type pantograph on a train. According to iris condition, only TOME 2 push hook can be used for insertion.
