Summary:Embodiments of the invention are generally directed to apparatus and methods for measuring a deformation characteristic of a deformable target surface. The measurement principles of the invention may be applied to a large variety of organic (e.g., human, animal or plant tissue) and inorganic materials having a surface that can be deformed by an applied non-contact force. The surface may be light diffusing and non-transparent or non-diffusing and transparent. An illustrative embodiment of the invention is directed to a device for measuring a deformation characteristic of a cornea. The device comprises a corneal topographer and a non-contact tonometer that is operationally integrated with the corneal topographer. In an aspect, the corneal topographer is a rasterstereography-based topographer. Use of the inventive device enables a method for measuring a deformation characteristic of the cornea. In addition to the measurable deformation characteristics listed above, dioptric power, intraocular pressure, corneal h
