CGS Meeting Wet Labs

Learning Objectives

  • Identify proper location of the various MIGS devices
  • Describe the implantation techniques for MIGS devices
  • Identify preferred MIGS device(s) to implement into current practice


The Canadian Glaucoma Society Wet Labs will run from 1:30pm – 4:00pm. Participants will rotate through 10 stations of Xen, Hydrus, iStent, Preserflo and Kahook Dual Blade in 15-minute increments. Each device with have one station with two scopes.

The CGS Wet Labs are physician led and will have a ratio of 2:1 for participant to physician expert.

At each station, physician leads will provide an overview of the simulation and the knowledge areas that will be tested. Participants will work through the implantation of the device, while receiving live feedback from the physician. Once the first round is completed, the participant will receive feedback from the physician to incorporate into three to four more simulation practices of implantation.

All feedback from the physician to participant will be given during the simulation and live.

During the simulations, participants will test their knowledge areas in expanding their current competenciesor developing new implantation techniques. For each of the devices, participations will:

XENDr. Sébastien Gagné

Understand the Xen 45 device, lumen size, length and inserting device.  During the simulation participants will understanding the conventional ab-interno insertion technique, feel of injector release, surgical positioning, incisions required, proper entry and exit from the eye. Participants will also have the opportunity to understand ancillary techniques to maintain flow, MMC augmentation and potentially alternative techniques for implantation.
