Clinical Solutions
PathFinder™ II Corneal Analysis Software
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

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 keratoconus*. An advanced Support Vector Machine algorthim analyzes multiple parameters from the mean curvature map and compares them to PathFinder II's extensive clinical database.

Mean curvature analysis eliminates corneal astigmatism to reveal underlying corneal irregularities
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 corneas**.
  • 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.
