The eyeWatch™ is inserted in a procedure analogous to standard trabeculectomy. The eyeWatch™ is positioned onto the sclera and covered with a patch (i.e., Tutoplast® or similar). The nozzle of the device is inserted into the anterior chamber via an opening created with a 26-gauge needle. The device is secured onto the sclera with simply Nylon® stiches. A standard seton tube device (inserted prior to the eyeWatch™) is then connected to the rear side of the eyeWatch™.
The adjustment of the IOP levels is performed using the eyeWatch Pen. The adjustment procedure is simple and atraumatic. After measurement of the IOP, using standard tonometry equipment, the eyeWatch™ implant is adjusted by following these steps:
Step 1: Reading of the current position of the eyeWatch™ implant. This is simply achived by placing the measuring compass on top of the implant. The scale 0 – 6 indicates the relative position of the implant, 0 corresponding to a fully open position and 6 corresponding to a fully closed position.
Step 2: Placement of the magnet of the control unit on top of the magnet position measured in step 1.
Step 3: Adjustment of the position of the implant by turning the magnet around the implant until the new selected position.
Step 4: Reading and verification of the new position of the implant using the compass.
After the adjustment, another IOP measurement is performed. This may require having the patient at rest for a period of about 15 minutes, allowing IOP to reach a new steady state. The adjustment procedure may be repeated as requested if the IOP level has not reached the target level.
Early data from a pilot clinical trial in Lausanne provide clear evidence of the clinical benefits of the technology:
Easy implantation using standard surgical procedures
Adjustment of IOP levels is a safe, fast and easy procedure
Clear limitiation of the early-phase hypotony and the related complications
Prevention of corneal touch and damage to the endothelial cells
