1. A method for performing a capsulotomy using a capsulotomy device, comprising:
receiving fluid from a fluid line of a phacomachine via an interface of the capsulotomy device;
delivering the received fluid into a space between a suction cup of the capsulotomy device and a surface of an eye via an irrigation inlet opening of the suction cup, wherein the suction cup forms a single chamber that forms the space with the surface of the eye;
forming, via an aspiration outlet opening of the suction cup, a suction seal between the suction cup and the surface of the eye by removing at least a portion of received fluid from the space using suction from an aspiration line of the phacomachine, wherein the interface is configured to simultaneously enable the fluid from the phacomachine to enter the suction cup via the fluid line and the irrigation inlet opening and to enable the received fluid to be aspirated from the suction cup to the phacomachine via the aspiration outlet opening and the aspiration line;
driving, by a control console of the capsulotomy device, a series of electrical pulses through an elastic ring of the capsulotomy device to perform the capsulotomy, wherein the elastic ring comprises a conductive surface for tissue cutting; and
breaking, via the irrigation inlet opening, the suction seal by delivering additional fluid received from the fluid line, into the space.
