An ophthalmic surgical system includes a chassis comprising a laser source.The system includes a gantry coupled tothe chassis. The position of the gantry is adjustable. The system includes areference interface coupled to the gantry. The referenceinterface comprises an attachment interface at a distal portion of thereference interface, configured to couple to a patient interface fordocking with an eye. The reference interface is configured to move to a firstplate position proximal to the chassis and a second plateposition distal from the chassis. The system further includes an optical headunit coupled to the reference interface. The optical head unitcomprises a laser scanner and a beam splitter. The optical head unit isconfigured to move to a first head unit position near a proximal endof the reference interface and a second head unit position which is a lockablesurgical position near a distal end of the reference interface.
