Clinical benefits

No hypotony

The eyeWatch features a drainage tube which opening can be controlled externally. The eyeWatch can be closed in the first post-operative days to avoid hypotony

Reduction of corneal complications

The eyeWatch is small and rigid, thus reducing corneal damage and avoiding tube motility in the chamber. 

Limitation of strabismus

The eyePlate is designed to be inserted easily right between the rectus muscles thus reducing complications related to diplopia or strabismus. 

More details on the benefits below


The eyeWatch can be closed during the first post-operative days, to minimize over-drainage of aqueous humor, avoiding thus hypotony and its related complications. Subsequently, with the development of the fibrotic bleb, the eyeWatch is progressively opened, eliminating the need of re-interventions (suture lysis, stent removal, etc.).

Limitation of hypotony


The adjustment of the eyeWatch is performed externally using the eyeWatch Pen. The adjustment is easy to perform, it is a fast procedure (about 1 minute) and is completely atraumatic. 

Non-invasive adjustment


The eyeWatch system allows a very precise tuning of the IOP, which can be adapted according to each patient needs. 

Patient-specific IOP management


The eyeWatch's nozzle is small and rigid. This prevents contact of the nozzle with the cornea, avoiding thus related complications. A 26-gauge needle is used for creating the channel entry into the anterior chamber, much smaller than commercially available seton tubes, minimizing corneal endothelium damage.

No corneal touch
