Various ocular fixation devices are disclosed. One ocular fixation device (100, 200, 300, 500, 600) includes first and second rings (106-108, 206-208, 304-306, 506-508, 606-608), where at least one of the rings includes means for fixating ocular tissue of an eye. The means for fixating are arranged to grasp the ocular tissue of the eye and to release the ocular tissue of the eye based on rotation of at least one of the first and second rings. The ocular fixation device may also include one or more structures on which a surgical tool (450, 522, 616) can be mounted on the ocular fixation device at one or more locations. For instance, a dome (112, 204, 302, 504, 604) of the ocular fixation device could include one or more holes (614) that are configured to receive one or more projections from the surgical tool. As another example, a base (110, 202, 502, 602) of the ocular fixation device could include one or more notches (520) configured to receive a projection from the surgical tool.
