A docking method for an ophthalmic system may include the steps of aligning a docking unit of the ophthalmic system and an eye； generating an image of an internal structure of the eye by an imaging system； improving an alignment of the docking unit with the internal structure of the eye in relation to the generated image； and docking the docking unit to the eye. The generating the image step may include computing scanning data by a processor corresponding to a scanning pattern； storing the scanning data in a data buffer； transferring the scanning data by the data buffer to an output module； outputting scanning signals by the output module to one or more scanners based on the scanning data； and scanning an imaging beam with the one or more scanners according to the scanning signals.
