Contact lens

An ophthalmic apparatus adapted to project a waist of a beam of the light, such that a portion of the confocal region of the waist is projected onto the cornea. The source can be at least partially coherent and/or monochromatic. The source may be a laser or a laser diode. The beam can be a Gaussian beam, or a non-Gaussian beam. The apparatus can comprise a wavefront aberrometer, an axial eye length measuring apparatus or a refractometer.

Eye illumination apparatus and method

An interferometric axial eye length measurement apparatus having a light source adapted to produce a beam of partially coherent light, a first mirror and a second mirror disposed in the reference arm, and a processor adapted to control at least the second mirror such that a corneal interference peak and a second interference peak have a non-zero separation. There is at least one variable delay optical element having a delay signal, wherein the delay signal corresponding to a region between the corneal interference peak and second interference peak is substantially linear.
