The Medmont E300 USB Corneal Topographer offers the practitioner extreme accuracy for the mapping of a patients cornea. Using a PC, the patients full corneal history can be stored and accessed quickly and efficiently. A huge range of display options is now available providing the user with information that they previously would only have dreamed about.

The Advantages of the E300 Topographer

  1. Largest Capture Area of Any Placido Ring Topographer Providing Full Limbus to Limbus Coverage.
  2. Tear Film Surface Quality (TFSQ) Algorithm, Understand and Analyse Tear Film Breakup.
  3. Exceptional Accuracy With a Standard Deviation of Error of 2 μm, Considered the Gold Standard for Fitting Specialty Contact Lenses.
  4. Comprehensive Database of Contact Lens and Orthokeratology Lens Designs.

Analysis and display

Easily configurable to specific preference of the user, the E300 USB is able to present a wide variety of different display options, with up to four images per screen.

Examples of multiple images of the same type to identify trends, a difference display and acombination map which can present four different views (e.g. axial power, tangential power, elevation and video image) of one examination.

Zernike analysis software is also provided, including analysis of corneal height data and wave front error.
Individual Zernike components can be displayed and analysed.

Practice Management integration

Database integration with practice management systems and other Medmont products is now possible utilising Medmont Studio. This negates the need for multiple patient entry and improves markedly the efficiency of the practice. Several E300 USB units can operate on a local or geographically remote network, sharing a database.

The E300 USB Corneal Topographer has applications in a wide range of corneal analysis and treatment proce-dures, including: Orthokeratology, Keratoconus, Contact Lens fitting, Corneal Grafts, PRK and LASIK procedures.

Based on an unobtrusive compact cone designin corporating precision optics and using 32 rings with 9600 measurement points, the E300 USB provides detailed topography data over a wide area of the human cornea.

Coverage extends from a minimumring diameter of 0.25mm up to 14mm when using Composite Capture, which is ideal for detail edassessment of corneal pathologies and detail edcontact lens fitting.

Images are captured automatically with a simplealignment system and progressive storage of the four best images. Difficult surfaces or patients become a simple task.

The advanced analysis software corrects defocused, off-centered images and corrects for errors due tomis alignment, providing extreme accuracy. A simple image scoring system provides information to the user on the captured image quality.

Automatic fitting of RGP lenses, including multiple peripheral curves, toric, aspheric and conic designs is quickly andeasily performed with the E300 USB. An expandable database of standard lens designs is included.

Manual adjustment and repositioning of the lens can be performed, with the results presented on a simulated fluorescein display and a tear film clearance graph.

Changes in corneal topography maps are easily displayed with the difference map view, this map showing the change induced by orthokeratology lens wear.

The contact lens fitting package is fully integrated with the rest of the software. It supports the fitting of Multi-Curve, Toric, Custom Designed Lenses and Sclerals. The contact lens database provides standard lens designs.

Fully Automatic image capture makes patient testing simple and quick. Simply position the instrument, guided by the intuitive 3D focusing target, and the software does the rest. Each video frame is analysed for centering, focus and movement. The best four frames are automatically captured and displayed in the image windows above.
