The Graether Collar Button offers a wide range of surgical advantages during anterior segment surgeries. These advantages come in handy for manipulating the iris and the pupillary margin.

In addition, the instrument is available in straight and angled shank designs. This particular feature allows surgeons to pick between models according to the surgical scenario.

All our Graether Collar Buttons have solid, square handles with side vertical ridges. As a result, surgeons obtain a strong grip and comfort.
