Glaucoma surgery

Intraocular pressure is essentially controlled by the aqueous humour. If the aqueous humour drainage is disrupted or too much aqueous humour is generated, it builds up inside the eye and intraocular pressure rises.


During surgery, a type of artificial drainage is created for the aqueous humour through a very small opening in the sclera.

The aqueous humour can then drain from inside the eye and collects under the conjunctiva. A so-called bleb forms, improving aqueous humour drainage from inside the eye and lowering intraocular pressure.

New: XEN Gel Stent and iStent Inject® implant

The XEN Gel Stent and the iStent Inject® implant belong to the so-called micro-invasive glaucoma surgery (MIGS). Micro-invasive glaucoma surgery represents a modern and innovative glaucoma treatment option. The recovery is faster and there are fewer side effects compared with classic glaucoma surgery.
