Surgical Procedure

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™.

 
Adjustment Procedure

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.

Clinical evidence

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
