Ocular tissue separation areas having a barrier region are described herein. In one embodiment, the tissue separation area can have an implant placement site configured to accept an ocular implant. The barrier region can be located about at least a portion of the periphery of the implant placement site. The barrier region can include one or more barrier structures. An example barrier structure is a channel formed on one side of the tissue separation area with a corresponding ridge formed on the opposite side. The channel/ridge structure can be configured to impede epithelial ingrowth to the implant placement site.
