Abstract
An apparatus (10′) for detecting the surface topography of a cornea (24) of an eye (22) by dynamic or static projection of a pattern onto the surface of the cornea and detection of the pattern reflected by the cornea, providing preferably simultaneous detection of at least one optical property of a layer disposed beneath the cornea.
Claims23
An apparatus for detecting the surface topography of a cornea of an eye comprising:
- (a) means for dynamic or static projection of a pattern onto the surface of the cornea;
- (b) means for detecting the pattern reflected by the cornea;
- and
- (c) means for detecting at least one optical property of a layer disposed beneath the cornea, wherein said means for detecting at least one optical property comprises coherence tomography means.

A method for detecting the surface topography of the cornea of the eye, the method comprising:
- (a) projecting by dynamic or static projection of a pattern onto the surface of the cornea;
- (b) detecting the pattern as reflected by the cornea;
- and
- (c) detecting at least one optical property of a layer disposed beneath the cornea wherein said detection of said optical property of a layer disposed beneath the cornea is detected by coherence tomography.
