OCULUS Easygraph

Small and Almighty!

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.

Description

Highlights

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

 

 

 

 

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

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.

 

 

 

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

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

Additional Options

You can supplement the main functions of your Easygraph with various software modules customized to meet your individual requirements.

Software

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 Topographic Keratoconus Screening also helps you in progression follow-ups and where applicable, shows you whether and how the keratoconus has changed.

OCULUS OxiMap®

The 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

How Much Oxygen Really Reaches the Cornea?

Until now, only the oxygen transmissibility values for the center of a contact lens with -3.0 D were available. The OxiMap® shows the oxygen transmissibility depending on the lens material and the lens thickness. The OxiMap® is available for the most frequently sold spherical soft contact lenses. This impressive tool assists you in helping your patients select the most suitable contact lens.

The OxiMap® is individually adapted based on the lens power and supports you in your consultation with the patient and helps you to choose the most suitable contact lens. New materials used for soft contact lenses provide excellent oxygen transmissibility.

OxiMap® was developed in close cooperation with JENVIS Research and the University of Applied Sciences in Jena.
