Micro-invasive glaucoma surgery (MIGS): HFDS



HFDS stands for High Frequency Deep Sclerotomy ab interno. In microinvasive glaucoma surgery (MIGS), HFDS provides direct access from the anterior chamber to Schlemm's canal and further into the sclera, thus bypassing the resistance of the trabecular meshwork. The HFDS glaucoma tip is inserted through a 1.2-mm paracentesis and uses diathermy delivery to create six small sclerotomy pockets in the chamber angle, which ensure improved drainage of aqueous fluid.


Ahmed glaucoma valve


The drainage system with a unique valve function. 

Successfully tried and tested in a clinical setting for many years, the Ahmed valve impresses with its unique valve function. This prevents a hypotonic drop in intraocular pressure following an operation. The silicone or PMMA implant consists of a valve plate, a valve, and a drainage tube that is placed in the anterior or posterior chamber. The implant is available in different sizes and designs and is also ideal for use with children.

Would you like to improve your results with trabeculectomies, viscocanalostomies or deep sclerectomies? Here is your solution.

Healaflow is a viscoelastic implant to help reduce pressure in combination with trabeculectomy, viscocanalostomy or deep sclerectomy. The gel-like implant is injected under the scleral flap and conjunctiva and dissolves over the course of a few months, while keeping the space created during the procedure open so as to improve drainage of the aqueous humor. Healaflow is non-toxic, is not of animal origin, and has anti-inflammatory properties.

Kahook Dual Blade®


A sustainable, minimally invasive ab interno trabeculectomy with the Kahook Dual Blade is currently one of the most attractive surgical methods for patients with glaucoma.

The Kahook Dual Blade® is an FDA-approved single-use ophthalmic knife for performing ab interno trabeculectomies that was designed for precisely excising a section of the trabecular meshwork which has ceased to function.

ologen™ Collagen Matrix


Using the ologen™ Collagen Matrix for healing wounds from ophthalmic and glaucoma surgery


The ologen collagen matrix (ologen™ CM) is a modern product for treating wounds that consists of a porous matrix of cross-linked atelocollagen and glycosaminoglycan (GAG). ologen was specially developed to promote scar-free wound healing by guiding the engraftment of fibroblasts during various ophthalmic operations, in order to form a healthy, prominent filtering bleb during glaucoma surgery, for example. ologen can be used for deep sclerectomies and trabeculectomies. The collagen matrix has an extremely porous structure and is broken down completely. Healing wounds in the eye is supported by wound modulation and randomised collagen deposition to ensure the wounds heal in a scar-free, physiological manner.
