The invention relates to an assembly comprising an orbital implant of substantially spherical shape intended to replace an eyeball after enucleation and / or evisceration and at least one suture thread. The implant consists of a basic body (1) made of porous material, in particular which promotes colonization by the body, and a posterior or rear element (2) with through windows； the posterior element comprises a plurality of through windows for the passage of sutures which defin a reference axis of the implant of substantially spherical shape passing through its center, a vertical axis Z corresponding to anterior-posterior axis and two XY axes in the equatorial plane, and a coordinate system with respect to which the angles of latitude and longitude are defined from any point to the surface of the implant； wherein the longitude angle of the most posterior or rear pole, called the upper pole, is 90 degrees while the longitude angle of a point at the equator is 0 degree. The window element (1) comprises at least a first lower through window (7), which extends over a first lower range of longitudes, and at least a second upper window (9), which extends over a second upper range of longitudes； there is at least one meridian (M) extending from the equator to the pole which crosses or passes through the two lower windows (7) and the two upper windows.
