August 2012 EWINTERNATIONAL 59 Xenoplast implantation Complete long-term success was achieved in 75% of cases observed during a post-op observation period of 2-10 years. A qualified success was achieved in 87% of cases. The num- ber of medications used was reduced IOP compared with those patients who were treated only with drops. CAD remains one of the most popular antiglaucomatous devices in Russia and the Ukraine. EW Editors' note: The authors have no fi- nancial interests related to this article.
