| ZEISS CONTACT DAY COMPATIC Spheric | ZEISS CONTACT DAY COMPATIC Toric |
|---|---|
| DIA corneal diametre +2.0 mm (variations of 0.5 mm possible, also with prominent CSP, smaller corneal diameters or poor mobility, change to 13.6) |
DIA corneal diametre +2.5 mm (variation of 0.5 mm possible, ZEISS compatic toric fit tendencially smaller, ZEISS air_toric fit tendencially bigger) |
| BC flac corneal meridian > 8.0 // BC = 8.8/8.9, flac corneal meridian ? 8.0 // BC = 8.6 |
BC add 0.7 mm to flat corneal meridian (variation of +/-0.3 mm possible) |
| D sphere +1/2 cylinder calculate to vertex distance = 0 |
D sphere +1/2 cylinder calculate both main meridians to vertex distance=0 |
