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 consisting of a body (1) in one base. porous material, in particular which promotes colonization by the body, and a posterior or rear element (2) with through windows covering a part of the basic body, the posterior element comprising a plurality of through windows for the passage of sutures for suturing the oculomotor muscles in and out of the space defined between the base body and the posterior element, and by defining for the implant of substantially spherical shape a reference mark passing through its center, a vertical axis Z corresponding to l anterior-posterior axis and two XY axes in the equatorial plane, coordinate system with respect to which the angles of latitude and longitude are defined from any point to the s urface of the implant, the longitude angle of the most posterior or rear pole, called the upper pole, being 90 ° while the longitude angle of a point at the equator being 0 °, characterized in that 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, and 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 (9) upper.L'invention concerne un assemblage comportant un implant orbital de forme sensiblement sphérique destiné à remplacer un globe oculaire après énucléation et/ou éviscération et au moins un fil de suture, l'implant étant constitué d'un corps (1) de base en un matériau poreux, notamment qui favorise la colonisation par l'organisme, et un élément (2) postérieur ou arrière à fenêtres traversantes recouvrant une partie du corps de base, l'élément postérieur comportant une plurali
