Ophthalmological analysis method and analysis system

An ophthalmological analysis system for measuring an intraocular pressure in an eye, comprising:

• (i) an actuating device that can deform a cornea of an eye in contactless manner, wherein the actuating device applies a puff of air applied the eye in such manner that the cornea is deformed;
• (ii) an observation system that observes and records a deformation of the cornea, wherein the observation system creates sectional images of the cornea when the cornea is deformed or when the cornea is not deformed or when the cornea is deformed and when the cornea is not deformed;
• and
• (iii) an analysis device that derives an intraocular pressure from the sectional images of the cornea,
• wherein a structural characteristic or a material characteristic or a structural characteristic and a material characteristic of the cornea can be derived from the sectional images of the cornea in the analysis device, wherein a corneal stress is derived as the structural characteristic or the material characteristic or the structural characteristic and the material characteristic, wherein the stress is rendered visible in the material of the cornea.

An ophthalmological analysis method for measuring an intraocular pressure in an eye with an analysis system including an actuating device with which a cornea of the eye is deformed in contactless manner, the method comprising the following steps:

• (a) applying a puff of air to an eye with an actuating device in such manner that a cornea of the eye is deformed, wherein the actuating device includes a pump;
• (b) observing and recording a deformation of the cornea with an observation system, wherein the observation system comprises an illumination device and a camera device, wherein both the illumination device and the camera device are equipped with a polarizer, and wherein the illumination device is a slit lighting device and the camera device is a Scheimpflug camera;
• (c) creating sectional images of the cornea when the cornea is deformed or is not deformed according to step (a) with the observation system;
• and
• (d) deriving an intraocular pressure from the sectional images of the cornea with an analysis system, wherein the analysis system is designed in the manner of a polariscope,
• wherein a structural characteristic or a material characteristic or the structural characteristic and the material characteristic of the cornea are derived from the sectional images of the cornea in the analysis device, wherein a corneal stress is derived as the structural characteristic or the material characteristic or the structural characteristic and the material characteristic, wherein the stress is rendered visible in the material of the cornea.
