Abstract
An ophthalmic instrument is constructed with an aligning axis for aligning the instrument to the cornea of an eye and first and second operating modes. The first operating mode measures the corneal curvatures in two orthogonal planes and the second operating mode examines at least the surface of the cornea. The instrument has an eyepiece, an imaging system, and a reflecting system. The eyepiece is disposed on the aligning axis. The imaging system has an axis that is displaced from and substantially parallel to the aligning axis and is used in the first and second modes. The reflecting system displaces an image from the aligning axis to the optical axis and provides an erect image of the displaced image at the eyepiece in the second mode.
