Embodiments of the present invention provide a method and system of treating intraocular pressure. Laser light is directed to the ciliary region of the target eye. The light stimulates the ciliary region and ablates debris lodged therein. An immune response may be triggered by the stimulation of the ciliary body. Intraocular pressure is reduced by the increase in aqueous flow from the anterior chamber in the eye permitted by the resultant removal of debris blocking the uveo-scleral outflow pathway.

Delivery devices, systems and methods are provided for inserting an implant into an eye. The delivery or inserter devices or systems can be used to dispose or implant an ocular stent or implant, such as a shunt, in communication with the suprachoroidal space, uveal scleral outflow pathway, uveoscleral outflow path or supraciliary space of the eye. The implant can drain fluid from an anterior chamber of the eye to a physiologic outflow path of the eye, such as, the suprachoroidal space, uveal scleral outflow pathway, uveoscleral outflow path or supraciliary space. Alternatively, or in addition, the implant can elute a drug or therapeutic agent. The delivery or inserter devices or systems can be used in conjunction with other ocular surgery, for example, but not limited to, cataract surgery through a preformed corneal incision, or independently with the inserter configured to make a corneal incision.
