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. Contact Lens Fitting and Fluorescein Image Simulation A list of recommended contact lenses available from well-known manufacturers is generated based on your patient’s corneal topography data. Prior to fitting, fluorescein images can be simulated and adjusted (rotate, offset, change parameters). OxiMap® – Visualization of the Oxygen Transmissibility of Soft Contact Lenses Easy to understand OxiMap® presents a color map of the oxygen transmissibility of soft contact lenses based on the lens power, which is easy to understand – even for your customers! 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. This compact topographer is a combination of a topography system and an integrated keratometer. In the non-contact examination process, 22,000 measuring points are used to map the cornea. Digital image transmission and automatic release guarantee the best possible reproducibility. Simple Mounting on the Slit Lamp. The Easygraph comes complete with a slit lamp adapter and optional guide rail. 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 color map 3D and 2D display Various color 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. The first placement of the contact lens and initial checking of the fit take place without any actual physical contact – simulated on the PC. This saves time and paves the way to the ideal contact lens for the patient. For hard contact lenses, a fluo-image is simulated based on the topography and the contact lens data. The contact lens can be moved with the click of a mouse, and can be rotated too for optimal fitting of toric contact lenses. After the virtual contact lens has been positioned on the real eye, the fluo-image simulation is recalculated and can be compared with realistic, static and dynamic images. 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 color-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. Software Keratoconus Detection at the Highest Level Thanks to topography measurement, corneal abnormalities can often be detected and diagnosed in the early stages. The measurements are compared with those in a norm database. If abnormalities are present, the measured values are displayed in yellow or red. If a keratoconus is present, it is classified based on the existing topography. The indices map also helps you in progression follow-ups and where applicable, shows you whether and how the keratoconus has changed. Zernike-Analysis Corneal abnormalities can be displayed in 2D and 3D using the Zernike Analysis. The displayed aberration coefficient provides information about the optical image quality of the cornea. In addition to this corneal wavefront analysis, the software also marks the location of the apex and is easy for the user to recognize.
