| Visante® omni – case examples |
| |
|
| | Case 1: Normal Cornea
The anterior map shows a regular WTR bowtie astigmatism. The anterior mean curvature map is symmetrical with a max power of 44 D. The minimum pachymetry is 510 microns and the Relative Pachymetry map is uniform with no significant localized thinning. Both anterior and posterior elevation maps show less than 2 microns of elevation.
|
|
| | Case 2: Visante® omni posterior topography rules out keratoconus
The Relative Pachymetry Map is uniform with a minimum pachymetry of 524 microns, and there is no significant posterior elevation. |
|
| | Case 3: Visante® omni confirms localized thinning and posterior elevation
This case shows an area of localized thinning on the 8%, but the change in Relative Pachymetry across the cornea is more like 12%, which can be considered abnormal. The posterior elevation map is also 11 microns elevated. |
|
| | Case 4: Visante® omni confirms localized thinning and posterior elevation
The Mean Curvature map shows a maximum of more than 49D. The change in Relative Pachymetry across the cornea is larger than 12%, and there is 37 microns of elevation posteriorly. |
