Abstract Details
Purpose:
To report the very first surgical cases of a continuously adjustable glaucoma drainage device (GDD) in glaucoma surgery using seton tubes.
Setting:
Clinique de Montchoisi, Lausanne, Switzerland
Methods:
Mono-centric clinical study. After placement of a classical seton tube, the eyeWatch was inserted into the anterior chamber through a 25G channel. After securing the implant onto the sclera, the device was then connected to the seton tube. The implant was covered by a scleral patch. A magnetic system enables the opening or closing of the system to provide an adjustment of the intraocular pressure (IOP). During the postoperative follow-up, the eyeWatch system can be used to adjust the IOP preventing early postoperative hypotony. The main outcomes were mean IOP, mean number of antiglaucoma medications and postoperative complications
Results:
18 patients were operated, with a mean follow-up of 6.6�Â�±3.9 months. The mean baseline IOP was 26.1�Â�±10.6 mmHg and the number of antiglaucoma medications (AGM) was 2.9�Â�±0.9. The mean postoperative pressure after 1 month was 13.8�Â�±5.3 mmHg and AGM was 0.6�Â�±0.9, and after 6 months IOP was 12.5�Â�±3.9 mmHg and AGM was 0.9�Â�±0.8. The IOP was well controlled throughout the entire follow-up period and no cases of effective hypotony were recorded.
Conclusions:
The eyeWatch can easily be implanted during glaucoma surgery using seton tubes. This system better addresses the hypotony phase observed after insertion of tubes enabling a proper IOP control. Finally, the portion of the implant placed in the anterior chamber has a fixed angle to prevent corneal touch and is of a much smaller diameter compared to the classic seton tubes what could prevent endothelial cells alteration leading to late corneal decompensation.
