Devices, methods and kits are described for reducing intraocular pressure. The devices include a support that is implantable within Schlemm's canal and maintains the patency of the canal without substantially interfering with transmural fluid flow across the canal. The devices utilize the natural drainage process of the eye and can be implanted with minimal trauma to the eye. Kits include a support and an introducer for implanting the support within Schlemm's canal. Methods include implanting a support within Schlemm's canal, wherein the support is capable of maintaining the patency of the canal without substantial interference with transmural fluid flow across the canal.
