EW SHOW DAILY 31 and scheduling your initial iStent cases toward the end of the OR day. Practicing gonioscopy was a thought echoed by Robert J. Cionni, MD, Salt Lake City, who also recommended use of the web- site www.gonioscopy.org. "Although a learning curve is certain, the procedure is elegant and artful," said Dr. Cionni. Glaucoma specialist Thomas W. Samuelson, MD, Minneapolis, shared some of the clinical evidence behind the iStent. The existing studies demonstrate how the device offers sustained long-term IOP re- duction and decreased medication use following phaco and single iStent implication. "There are some data being pub- lished now that are even better than that from the U.S. trial, but we know that the iStent has a learning curve," Dr. Samuelson said, noting that the learning curve in the earlier study likely affected clinical results. "There's still a lot we don't know about the iStent and that we're learning," he said. The available results show the iStent is effective to treat mild to moderate glaucoma, Dr. Samuelson said. He will sometimes use the iStent in more advanced glaucoma cases, but he will treat them slightly differently. Some additional surgical pearls for iStent implantation, according to Paul Singh, MD, Racine, Wis., include hydrating the wound and paracentesis prior to viscoelastic material insertion, using just enough viscoelastic material (too much can compress the canal while too little will make it hard to see the angle), and using a moderate amount of gonioprism pressure. John P. Berdahl, MD, Sioux Falls, S.D., addressed, among other topics, how to better educate patients about the iStent. Opportu- nities to reach patients include via your website, phone on-hold service, welcome packets and greetings, lobby materials and DVDs, technician introduction, patient exam lanes, and via the referring physician. Dr. Berdahl also uses visual aids to show patients how small the iStent actually is. EW Editors' note: This event was supported by an educational grant from Glaukos.

However, Dr. Donnenfeld advised that before going full force with the iStent, cataract surgeons should be mindful of the learning curve involved. "Spend some days doing gonioscopy before doing your first MIGS procedure," Dr. Donnenfeld suggested. He also recommended practicing in wet labs
