CA-800 ease of use The CA-800 is extremely easy to handle and use. From image acquisition to analysis, the onboard software is intuitive, user friendly and the 10.1 inch capacitive touchscreen provides quick navigation. Visual guidance supports fast and easy alignment and focusing of the instrument; the “best image” selection modus automatically acquires the best focused image. Contact lens fitting The Topcon CA-800 is the perfect support for contact lens fitting. A simulation software is provided onboard including a complete contact lens database for all the main manufacturers (upgradable and customizable by the user). The onboard fluorescein acquisition system allows full control of the contact lens position on the eye. Thanks to the onboard pupillometer the user can check the pupil position and diameter (from photopic to scotopic condition) in relation to the position of the optical zone in Ortho-K or refractive surgery treatments.
Pupillometry, fluorescein & meibography
The Topcon CA-800 is a placido-based topographer with 24 rings that measures up to 6,144 data points, with axial and instantaneous curvature evaluation. Moreover, it is equipped with four infra-red LEDs and two white LEDs for dynamic and static pupillometry and eight blue LEDs for fluorescein images and videos to carry out full contact lens analysis. With the four infra-red LED’s meibomian glands can easily be analyzed for any possible defects.
Fast, comprehensive analysis of the cornea
Curvature mapping
The CA-800 corneal analyzer is a comprehensive solution for evaluation of the anterior corneal surface. In addition to curvature mapping which can also be displayed in 3D, the instrument provides a complete analysis of the cornea including the keratoconus probability index and height map of the corneal surface. The Topcon CA-800 also provides fluorescein imaging and real time fluorescein videos for contact lens fitting.
Non-invasive tear film analysis
The CA-800 offers a comprehensive analysis of the Tear Film by using the Blink Detection and Tear Breakup Time measuring modes. The Blink Detection automatically detects blinks and calculates the average blinks per minute and blinks interval. The Tear Breakup Time (TBT) records the patients tear film condition while they hold their blink and calculates the time of first breakup and average time for breakup of the Tear Film. This new feature allows video playback with a colored overlay to show the quality of the corneal surface and is extremely easy to interpreted using color coded sectors.
