The Eye Surface Profiler (ESP) offers the precise limbus-to-limbus topography required for successful OrthoK fitting.
The ESP has revolutionized the way scleral lenses are fit. The same precision can now be applied to OrthoK fitting.
The Eye Surface Profiler (ESP) offers an OrthoK module to fit and provide precise follow-up care for orthoK patients.
Use the ESP to get a scan of the complete cornea, limbus to limbus.
Remember that these baseline scans are the most important as these will be used for your comparisons to treatment maps going forward.
Go to the First Lens Fit OrthoK tab and select the Supplier and Lens you want to design. Click on Calculate and all the first lens parameters will be calculated, including the lens diameter based on the HVID value.
Use the ESP to get a follow up scan of the complete cornea.
Use the automatic generated difference maps to compare the follow up maps to the baseline scans: | Axial curvature and Power profile maps give you data about the change in corneal power (Figure 1 & 2). | Tangential curvature map shows you the lens position and is most helpful to evaluate lens centration (Figure 3).
