The slit-lamp and biomicroscope can be moved in

headrest to hold the patient still and the
adjustable table or stand instrument for holding the
slit-lamp biomicroscope to position it before the patient.
The accurate term for the instrument is the slit-lamp biomicroscope, however, by convention each individual term is used to refer to the whole instrument.
