Glaucoma is an eye disease caused by raised pressure within the eye.

It is the number one cause of irreversible blindness worldwide, affecting nearly 80 million people.


Glaucoma is especially common, more severe, and

more difficult to treat within the African population.

The OptiShunt device is Liqid Medical's flagship device. OptiShunt is a patented ocular implant designed to be the world's first definitive treatment for severe and refractory glaucoma and pioneer a new class of glaucoma surgery known as Maximally Effective Glaucoma Surgery (MEGS).

First-in-Man clinical trials are planned to commence at Groote Schuur Hospital, Cape Town, in the last quarter of 2019.
