Title:
SYSTEM FOR CHARACTERIZING A CORNEA AND OBTAINING AN OPHTHALMIC LENS
Document Type and Number:
Japanese Patent JP2015221375
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a system for determining the shape of a cornea of an eye.SOLUTION: The system illuminates at least one of the interior surface, the posterior surface, and the interior region of the eye with infrared light of a wavelength that can generate fluorescent light from the portion of the cornea illuminated. The generated fluorescent light is then detected. A step of illuminating can comprise focusing the infrared light in a plurality of different planes substantially perpendicular to the optical axis of the eye. From the detected light it is possible to create a map of at least a portion of the interior surface, at least a portion of the posterior surface, and/or portion of the interior region of the cornea. Clarity of vision can be determined by generating autofluorescence from proteins in the pigment epithelial cells of the retina.
