Geuder Yamane Double Needle Stabiliser

Description

Fixing ring and needle guide for flanged intrascleral IOL fixation. The Yamane double needle stabiliser simplifies the location of the sclerotomy positions and provides control over the insertion angles to form the intrascleral tunnels. Thanks to its ring shape and the fixing teeth, it also offers excellent eye fixation when the needles are inserted.

Challenge

When performing Yamane’s double-needle technique, you find your sclerotomy sites by combining the use of an axis marker, caliper, and ink. In addition, when piercing the conjunctiva and advancing through sclera, you have no control over recommended insertion angles for creating the scleral tunnels. The combination of these variables are a challenge for reproducibility and standardisation.

Solution

The Yamane double needle stabiliser simplifies the location of the sclerotomy positions and provides control over the insertion angles to form the intrascleral tunnels. Thanks to its ring shape and the fixing teeth, it also offers excellent eye fixation when the needles are inserted.

Advantages

The instrument has two landmarks for visualisng the sclerotomy positions, which are 2 mm from the limbus and 180 ° apart. Thus it replaces the use of an axis marker, compass and colour.

Since it is difficult to insert a needle with a free hand at a certain angle, the instrument offers two grooved plates to guide the needles through the annular grooves. This makes it possible to insert the needles at a predetermined angle of 20 ° with respect to the limbus and 10 ° with respect to the iris surface in order to form reproducible scleral tunnels and to avoid stress on the IOL haptics.
