In a method for introducing a retinal implant to a position within a subretinal region of an eye, the following steps are performed: a) preparing a fornix-based scleral flap at a distance from the limbus; b) detaching the retina by subretinal injection of balanced salt solution, from the vitreous cavity and creating a localized bubble in the area of the scleral flap; c) performing in the upper hemisphere of the eye a peripheral retinotomy and detaching a part of the retina; d) advancing the implant into the subretinal space and placing an inner portion of said implant on the retinal pigment epithelium onto the desired position; and e) closing the sclera flap.
