Small, but efficient as a big one !
The Easygraph offers the ideal solution to practices struggling with limited space. Mounting directly on the slit lamp, this space-saving corneal topographer incorporates assessment of the cornea directly into the examination process. The Easygraph uses the same precise measuring technology as the Keratograph and is both a topographer and a keratometer combined into one unit. Numerous analysis and display formats support you in the quantitative classification of the cornea. The optionally available Contact Lens Fitting and OxiMap® software modules can also be integrated to add confidence and trust to all contact lens consultations.
- The Easygraph – The Small Performance Wonder
The Easygraph works with the tried and tested measuring and device technology that has become indispensable in today’s contact lens fitting and reliable diagnostics fields. Ideal where space is limited.
Functions
Compact Corneal Topographer
The Easygraph combines small construction with grand technology. The tried and tested measuring system is identical to that of the keratograph.
Simple Mounting on the Slit Lamp.
The Easygraph comes complete with a slit lamp adapter and holder. These make it easy to move the Easygraph from the work position to the idle position. After using the Easygraph, you can resume the examination with the slit lamp as normal.
Precise Measurement, Easy-to-Understand Presentation
Precise measurement is the basis for many types of analysis. Graphic presentation of the data supports you in the evaluation and quantitative assessment of the corneal topography:
- Overview with camera image and colour map
- 3D and 2D display
- Various colour maps
- Plot of the Fourier analysis
- Refractive map
- Height map of the topography data
- Map of the sagittal and tangential radii
- Comparison of different examination results for follow-up purposes
Contact Lens Fitting
The topography data provide the contact lens fitter with comprehensive support, whether he is a specialist or a newcomer to the job.
Progression Follow-up Diagnostics
Regular progression follow-ups are essential, not only for cases of keratoconus. In the “Compare examination“ display, up to four examinations can be directly compared with each other and any changes of the corneal topography can be displayed with colour-coding.
Display of Refractive Corneal Changes
Changes in the refractive power of the cornea as a resulting of wearing of Ortho-K contact lenses or of refractive surgery can be analyzed and documented.

Verständliche Kundenaufklärung
Vergleichen Sie unterschiedliche weiche Kontaktlinsen miteinander!
Die Dk/t-Werte werden farblich kodiert, wobei schwarz einer Sauerstoffversorgung geringer als bei geschlossenen Augen entspricht. Um die Integrität der Cornea auch beim Tragen von Kontaktlinsen zu wahren, werden abhängig von der Kontaktlinsen-Tragezeit Mindest-Dk/t-Werte empfohlen. Die Farbkodierung der OxiMap® basiert auf diesen international gültigen Empfehlungen.
OxiMap® wurde in enger Zusammenarbeit mit JENVIS Research und der FH Jena entwickelt.
