Abstract: A corneal topographer, and a method for corneal topography are disclosed. In one embodiment, the topographer includes an illumination projection subsystem to project a series of preselected different stationary patterns of one or more slits of light in ordered succession onto the surface of the cornea. An image capture subsystem captures a still image of each projected pattern. An image processing subsystem converts the still images into topographical information of the cornea. The method involves projecting a series of preselected different stationary patterns of one or more slits of light in ordered succession onto the surface of the cornea, capturing a still image of each projected pattern and converting the still images into topographical information of the cornea.

Abstract: This invention is directed to a corneal topographer (1) and a method for corneal topography. The topographer (1) includes an illumination projection subsystem to project a series of preselected different stationary patterns of one or more slits of light in ordered succession onto the surface of the cornea (100),an image capture subsystem to capture a still image of each projected pattern and an image processing subsystem to convert the still images into topographical information of the cornea. The method involves projecting a series of preselected different stationary patterns of one or more slits of light in ordered succession onto the surface of the cornea, capturing a still image of each projected pattern and converting the still images into topographical information of the cornea.
