What is HFDS®?

HFDS (High Frequency Deep Sclerotomy) is the implant-free MIGS solution for glaucoma treatment. But what exactly is HFDS? This video explains in which cases the HFDS procedure is used and which instruments are applied.

The HFDS® procedure

The HFDS (High Frequency Deep Sclerotomy) procedure is an implant-free MIGS procedure to lower intraocular pressure by reducing the outflow resistance of the aqueous humour. In this animation, all surgical steps of the HFDS procedure are explained.

Recent studies & postoperative treatment

With HFDS, a reduction in intraocular pressure is already noticeable in the first few days after the operation. In the following video you will learn why you do not need pressure-reducing eye drops and how the reduction in intraocular pressure is measured using the latest studies.
