    PathFinder II Corneal Analysis Software

    Take the art out of topography analysis

    PathFinder II Corneal Analysis Software for the Atlas Corneal Topography System (Model 9000) is a comprehensive, easy to understand, and reliable anterior topographic screening tool to assist with refractive surgery screening and to help identify abnormal corneal conditions for monitoring and follow-up. Using next-generation analysis technology, PathFinder II instantly provides probabilities for 5 different corneal conditions by comparing topography exams to an extensive clinical database.

    1. Comprehensive Clinical Database

    PathFinder II features a statistically significant clinical database established from a multicenter clinical study that characterized 5 different corneal conditions including:

    Normal corneas

    • Suspect/clinical keratoconus
    • Myopic laser vision correction
    • Hyperopic laser vision correction
    • Other non-normal conditions such as corneal transplant
    pathfinder II next generation analysis software

    Mean curvature analysis eliminates corneal astigmatism to reveal underlying corneal irregularities

    2. Sophisticated, Next-Generation Analysis Software

    Overcoming limitations inherent in traditional corneal topography, PathFinder II incorporates novel three-dimensional mean curvature analysis, which has been shown to be very sensitive to detecting corneal shape abnormalities such as keratoconus1. An advanced Support Vector Machine algorthim analyzes multiple parameters from the mean curvature map and compares them to PathFinder II's extensive clinical database.

    3. Results You Can Use

    You can count on PathFinder II to make topography analysis simple and reliable.

    • Validation of PathFinder II with an independent data set demonstrated greater than 90% sensitivity, specificity, and accuracy in detecting normal versus abnormal corneas2.
    • Color-coding of PathFinder II parameters quickly indicates which parameters are beyond normal limits any may contribute to specific classifications.
    • PathFinder II results may also be tracked over time to monitor changes in probabilities.

    MasterFit Contact Lens Software

    MasterFit™ Contact Lens Software helps streamline the fitting of gas permeable (GP) lenses.

    Corneal conditions such as asymmetrical astigmatism, a decentered apex, contact lens warpage, and irregular, peripheral and central astigmatism can dramatically affect the way a contact lens behaves on the eye. MasterFit II allows customized fitting of GP lenses according to your own fitting preferences.

    • Simulate fluorescein patterns for custom and stock lenses, including spherical, toric, and aspheric designs
    • Automatically design lenses to your preferences by customizing fitting options such as desired tear film clearance
    • Improve trial lens fitting efficiency by adjusting lens parameters, such as peripheral curves, and simulating lens movement to compensate for lens-to-cornea relationship
    • Email lens design and topography exam to your lab for efficient ordering and fulfillment
