The Siepser Knot Technique performed on our SimulEYE® Iris Suturing & IOL Fixation (ISIF).

Take a look at the Siepser Knot Technique performed on our SimulEYE® Iris Suturing & IOL Fixation (ISIF).

The Technique

The Siepser sliding knot technique for repairing iris lacerations is just one of many surgical techniques that can be practiced on the SimulEYE Iris Suturing and IOL Fixation (ISIF) model. After entering through a paracentesis and then out through the cornea, the suture is retrieved with a hook through the paracentesis. The free and tethered ends are identified to create the sliding knot which is then slid into and cinched down inside the eye. Multiple throws are performed before trimming the suture ends with intracameral microscissors.

The ISIF (Iris Suturing & IOL Fixation) Model

This model provides an eye with a flexible iris that can be easily cut and then repaired with various suturing techniques. The root of the iris can be disinserted to practice iridodialysis repair. Various IOL fixation techniques can be practiced including iris suture fixation, scleral suture fixation, and intrascleral fixation including the Yamane technique. In addition, IOL cutting and exchanges can be practiced. Multiple procedures can be performed on each model before the eye is consumed.
