A method of, and apparatus for, aligning an ophthalmic instrument relative to an eye is disclosed, and can include aligning an esthesiometer with a patient's eye. The method can include steps of: directing a beam of light from an ophthalmic instrument to an eye; taking, at a plurality of locations around the beam, measurements of reflections of the light from the eye; determining the position of the ophthalmic instrument relative to the eye from the measurements; and moving the ophthalmic instrument relative to the eye from the determined position to a desired position. The apparatus can include an aperture, a source of collimated light, a plurality of detectors, and a control unit. The control unit determines a position of the ophthalmic instrument relative to the eye and can move relative positions of the ophthalmic instrument and the eye from a determined position to a desired position.
