摘要： A device for determining biometric variables of the eye, as are incorporated in the calculation of intraocular lenses including a multi-point keratometer and an OCT arrangement. The keratometer measurement points are illuminated telecentrically and detected telecentrically and the OCT arrangement is designed as a laterally scanning swept-source system with a detection region detecting the whole eye over the whole axial length thereof. The multi-point keratometer ensures that a sufficient number of keratometer points are available for measuring the corneal surface. By contrast, telecentricity ensures that the positioning inadequacies of the measuring instrument in relation to the eye to be measured do not lead to a local mismatch of the reflection points. The swept-source OCT scan detects the whole eye over the length thereof so that both anterior chamber structures and retina structures can be detected and a consistent whole eye image can be realized.

摘要： The invention relates to an ophthalmological measuring system, for obtaining biometric data of an eye, provided with the necessary calibration and check means for monitoring the functionality and the calibration status. The ophthalmological measuring system at least comprises means for illuminating an eye with light and with means for recording and analysing back-scattered or reflected light components and a controller. At least one calibration and check system integrated in the ophthalmological measuring system for monitoring the functional and calibration status is provided. A device is also provided which houses the calibration and test means and which reads off the individual physical data therefrom by means of an interface. Said ophthalmological measuring system is in particular provided for determining biometrical data but can also be used for ophthalmological, dermatological or other devices which require calibration and/or functional checking at regular intervals.
