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 (Δ28), so that the angle between said insertion axis and a plane tangential to the virtual sphere at the insertion point (Pi) is less than 40°, the insertion point being the point where said insertion axis crosses said virtual sphere.
