Welcome everybody to this webinar. It's really great to have you around Australia and around the world. I've got a fantastic panel with me, so I expect to learn a lot from tonight. We will talk about glaucoma drainage devices and special emphasis on the Baerveldt, and a special thanks to Johnson & Johnson, Christine and her team to get it all together for us. I just have a disclosure; so we don't have any financial interest in any of the products discussed in this webinar, but certainly it’s been great having Johnson & Johnson on board to support this sort of educational symposium. We're going to look at various parts of the Baerveldt device - the preoperative, the insertion and postoperative care and how to get the most out of glaucoma drainage devices.
