| titleOfInvention | Eye measurement method and system |
| abstract | Disclosed is a method for determining at least one surface shape of a cornea (54) of an eye (50) by means of a measuring system. In said method, a fluorescent dye, especially fluorescin, is added to the tear film (53), a light pattern of strip-shaped lines (S) is projected onto the cornea (54), and fluorescent radiation from the excited dye in the tear film (54) is detected using a camera (14), the detected signals being evaluated to calculate the surface shape of the tissue (8a). The disclosed method is characterized in that a detected light pattern is composed of pixels which are clearly characterized by the two position coordinates (x, y) and the intensity value thereof, the intensity of each pixel in relation to the adjacent pixels thereof is determined, and the surface shape or a contour map of the cornea (54) is calculated from the three values for each pixel on the basis of calibration data. The invention also relates to a corresponding measuring system. |
