The Head of the Glaucoma and Research Department inserted the CyPass implants into the eyes of several patients during the live surgery at the ICR, which was watched by doctors from 12 different countries. As well as being able to learn about the details of the surgery first-hand, the participating physicians were able to ask questions in real time.
CyPass micro-stent device for glaucoma treatment
The CyPass micro-stent is a latest generation device that is implanted beneath the surface of the eye. The device acts to help drain excess fluid and prevent a build-up of pressure, which causes glaucoma. It does this with only minimal changes to the eye’s tissue structure.
Minimally invasive surgery
This kind of micro-implant is part of a series of new minimally invasive glaucoma surgery (MIGS) techniques. These have been developed in recent years with the aim of draining excess liquid (aqueous humour) from the eye. When this liquid accumulates it can cause an increase in eye pressure, leading to glaucoma. The new techniques have led to positive surgical outcomes without the risk of serious complications.
The device, which ICR surgeons have been using for over 5 years, is compatible with other types of glaucoma surgery. This is because the specific part of the eye in which it sits is not affected by or involved in other types of glaucoma procedure. This is an important advantage given that many glaucoma patients will have to undergo more than one surgery.
The devices are effective in early-stage or moderate glaucoma but are not recommended for very advanced stages of the disease. This is because in such advanced stages a very low eye pressure is required and the micro-stent is rarely capable of achieving this.
