The present application relates to an electroporation device for injecting a product into a ciliary muscle of an eye, said device comprising: - a support (16) having a support contact surface (18) extending along a virtual sphere (S) having a radius between 10 and 15 mm, so as to match the outside surface of an eye, - a first electrode (10) comprising an invasive electrode needle, - a second electrode having an electrically conductive electrode contact surface and - optionally an injection needle, wherein the support comprises an insertion guide (28) configured to guide a sliding of said electrode needle and/or injection needle along a respective insertion axis (” 28 ), so that the angle between said insertion axis and a plane tangential to the virtual sphere at the insertion point (P i ) is less than 40°, the insertion point being the point where said insertion axis crosses said virtual sphere.
