20110319740 | OPHTHALMOLOGICAL ANALYSIS METHOD AND ANALYSIS SYSTEM - The invention relates to an ophthalmological analysis method for measuring an intraocular pressure in an eye with an analysis system consisting of an actuating device, wherein the actuating device causes a puff of air to be applied to the eye in such manner that the cornea is deformed, an observation system with which the deformation of the cornea is observed and recorded, wherein sectional images of the cornea when it is deformed and not deformed are created with the observation device, and an analysis device with which the intraocular pressure is derived from the sectional images of the cornea, wherein a structural characteristic and/or material characteristic of the cornea is derived from the sectional images of the cornea in the analysis device, wherein a stress of the cornea is derived as a structural characteristic and/or material characteristic, wherein stresses in the corneal material are rendered visible. | 12-29-2011 |
20130050650 | Ophthalmological Analysis Instrument And Method - An ophthalmological analysis instrument includes a first analysis apparatus for measuring a curvature of a cornea of an eye, such as a keratometer or the like, and a second analysis apparatus. The second analysis apparatus includes a projection device and a monitoring device. The projection device includes at least one slit projection unit for projecting a light slit onto a surface of the eye. An image of the light slit is recordable by the monitoring device, the light slit being projectable onto a region of a limbus of the eye by the slit projection unit. A topography of the surface in the region of the limbus is derived from the image of the light slit imaged on the surface. | 02-28-2013 |
20130329187 | Method and Analysis Apparatus For Measuring A Cornea - A method and an analysis apparatus for measuring a cornea of an eye includes an ophthalmological analysis system. The ophthalmological analysis system measures a topography of a cornea in a measurement time interval to obtain a number of image data sets of a surface area of the cornea experiencing a change in intraocular pressure. A repeated change in the topography of the cornea is determined from the number of image data sets. | 12-12-2013 |
20140320815 | Method And Analysis System For Eye Examinations - An ophthalmological analysis system for examining an eye, in particular in the region of a front eye section of an eye includes first and second analysis systems obtaining sectional images of the eye. The first analysis system includes a projection device and a monitoring device arranged relative to each other according to the Scheimpflug rule. The second analysis system is an optical coherence interferometer. A processing device processes a first image data set obtained by the first analysis system and a second image data set obtained by the second analysis system to supplement the first image data set, at least partially, with data of the second image data set. | 10-30-2014 |
