A non-contact tonometer includes a fixation axis (12) intersecting the corneal vertex (7), and a fluid axis (18) angularly displaced from the fixation axis (12) to form a non-zero angle therewith. A nozzle (20) is axially aligned along the fluid axis (18) for discharging a fluid pulse along the fluid axis to the corneal surface (4) of the eye. In a preferred embodiment, the fixation and fluid axes (12, 18) reside in the same vertical plane, with the fluid axis (18) below the fixation axis (12) approaching the eye. Alignment and applanation detection optics are arranged coplanar with the fluid axis.
