OCULUS - Easygraph

A compact yet powerful corneal topographer and keratometer designed to bring advanced anterior corneal diagnostics directly into routine eye examinations. Built on the same proven Placido-based measurement technology used in OCULUS Keratograph systems, Easygraph combines high-resolution topography with integrated keratometry to capture detailed maps of the corneal surface using 22,000 non-contact measuring points with digital image transmission and automatic release for excellent reproducibility.

The unit mounts easily onto a conventional slit lamp, making it ideal for practices where space is limited or workflow efficiency is paramount. Its compact design doesn’t compromise performance: it delivers sagittal (axial) and tangential curvature maps, refractive power maps, elevation data, and multiple graphical displays (2D/3D and various colour scales) that support comprehensive corneal analysis and quantitative assessment.

Easygraph’s intuitive interface in a Windows™ environment and seamless PC connectivity (USB, network-ready) make operation straightforward, while its software tools enhance clinical value. Optional modules include contact lens fitting with simulated fluorescein imaging and a pre-programmed database to aid lens selection, topographic keratoconus screening with indices and Zernike analysis for early ectatic detection, and OCULUS OxiMap® to visualise oxygen transmissibility of soft contact lenses in a clear, colour-coded format for patient education.

The system also supports progression tracking by comparing up to four examinations side-by-side, helping clinicians monitor corneal changes over time — whether due to ectatic disease, contact lens wear, Ortho-K effects, or post-surgical outcomes. Mounted directly on the slit lamp, Easygraph enhances efficiency by integrating corneal topography into the examination workflow without needing dedicated standalone space.
