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.
