OS4 IN GLAUCOMA SURGERY
In operative treatment of glaucoma, the OS 4 has created significant added value in micro-invasive glaucoma surgery (MIGS). High Frequency Deep Sclerotomy (HFDS) ensures excellent long-term results and has an extremely low complication rate, and short intervention time.

MAKING THE DIFFERENCE IN GLAUCOMA SURGERY
«For me, HFDS is an easy to apply MIGS solution, which convinces not only because of the fast rehabilitation post-op. High frequency diathermy is used to reduce the outflow resistance and shows excellent eye pressure reduction. HFDS can be excellently combined with cataract surgery.»
Prof. Bojan PajicEye Clinic Orasis, Reinach, Switzerland
HFDS
HFDS stands for High Frequency Deep Sclerotomy. In micro-invasive glaucoma surgery (MIGS), HFDS creates direct access from the anterior chamber to the Schlemm’s canal and further into the sclera. The resistance of the trabecular meshwork is thus bypassed. The abee glaucoma tip is inserted through 1.2 mm paracentesis and, by means of diathermy output, it creates six small sclerotomy pockets in the iridocorneal angle, ensuring improved outflow of aqueous fluid.
HFDS can be used individually and can also be ideally combined with cataract surgery. HFDS is characterised by a very short intervention time. Bleb formation is prevented, and so is fibroblast movement to the sclerotomy. Moreover, there are no corneal scars. Oertli’s High Frequency Deep Sclerotomy boasts excellent long-term results. If required, a further HFDS intervention can be made to optimise results.
Advantages of HFDS
- Ideal in combination with cataract surgery or as individual application
- Very short intervention time
- Excellent long-term results
- No bleb-formation, no corneal scars
- Surgery can be repeated
- Very low complication rate
