Effect of Misalignment between Successive Corneal Videokeratography Maps on the Repeatability of Topography Data
Fig 4
Distribution of elevation difference between successive corneal topographies before and after correction for misalignment: Case 2.
Before ICP correction, the RMS of fit error was 12.07 μm for both anterior and posterior surfaces, considered simultaneously, and reduced by only 0.78% to 11.98 μm following correction.
