A multi-function surgical instrument for facilitating ophthalmic surgery of the eye (3) by laser means, included are a lower ring (1) and an upper ring (2). One or two intermediate rings may also be included. The lower ring (1) includes a central aperture (11) to capture the limbus and aid in positioning of the eye (3). Protuberances on the lower surface (18) of said ring (1), application of vacuum between the lower surface (18) of the ring (1) and the eye (3), or both may be used to more firmly grip the eye (3). Ports (14) disposed on the upper surface (13) of the lower ring (1) and connected to a vacuum source may be used to control hydration of the surgical field. Attached to structures of the lower ring (1) is a sterile platform (17) for reposing temporarily removed tissues (32) during the administration of laser pulses to other tissues. The upper ring (2) is disposed above the surgical bed. Ports (22) disposed along said upper ring (2) and connected to a vacuum source may be used to control smoke and splatters resulting from the ablative procedure and create additional airflow to further control hydration of the surgical field.La présente invention concerne un instrument chirurgical polyvalent permettant de faciliter la chirurgie ophtalmique de loeil (3) au moyen dun laser. Ledit instrument comporte un anneau inférieur (1) et un anneau supérieur (2) il peut également comporter un anneau intermédiaire. Lanneau inférieur (1) comprend un orifice central (11) pour saisir la limbe et aider au positionnement de loeil (3). On peut utiliser des projections sur la surface inférieure (18) dudit anneau (1), lapplication dune dépression entre la surface inférieure (18) de lanneau (1) et loeil (3) pour mieux saisir loeil (3). On peut utiliser les orifices (14) disposés à la surface supérieure (13) de lanneau inférieur (1) et connectés à la source de vide pour contrôler lhydratation du champ chirurgical. Fixée aux structures de lanneau inférieur (1) se trouve un plateau (17)
