Total diameter: standard 9.50 mm
Bitoric Geometry (BT):
The optimal fluorescein pattern shows a small fluor lake in the center and a larger fluor ring in the periphery (env. 0.75 mm).
Vertical movement should be around 1 mm. In case of too much movement, decrease both central back curves (r0fl and r0st) with -0.10 mm. In case of low riders increase both central back curves (r0fl and r0st) with +0.10 mm or in case the upper lid is pushing the lens down, increase the total diameter ØT.
In case of high riders, decrease total diameter ØT
In case of instable stabilisation and/or high riders, increase the prism to 2.0 cm/m.
WARNING: the stabilisation prism induce an optical prism. This should be adjusted on both eyes.
