The present invention relates to an injection device comprising: &mdasha first support (14) having a cup-shaped first contact surface (18) intented to come into contact with a first region of an outside surface of an eye, &mdasha set of at least four injection needles (17) in fluid communication with each other and protruding from said first contact surface (18) at respective insertion points (22) so that the distance between the distal end (26) of any of said injection needles to said first contact surface is between 0.6 mm and 1.3 mm, the insertion points of the injection needles on the first contact surface being spread on said first contact surface so that the diameter (D&prime) of the largest circle (C&prime) that it is possible to include completely in the convex surface (E) defined by said insertion points on a front view of said first contact surface, without any insertion point being included in said circle, is less than 8 mm.本発明は:眼球の外面の第一の領域と接触するように意図されたカップ状の第一の接触面(18)を有する第一の支持体(14)と、互いに流動的に連通し、任意の注射針の遠位端(26)から第一の接触面までの距離が0.6mm~1.3mmであるようにそれぞれの挿入点(22)において第一の接触面(18)から突き出る、少なくとも4個からなる一組の注射針(17)とを含む注射装置に関し、第一の接触面上の注射針の挿入点が第一の接触面に散在し、第一の接触面の正面図上の挿入点によって画定された凸面(E)に全面的に包含されることが可能な、円内にいかなる挿入点も包含しない最大円(C’)の直径(D’)が8mm未満である。
