USING THE INSTRUMENT
• Measuring a soft contact lens without astigmatism
1 Use the contact lens support for measuring as measuring a hard contact lens.
2 Select and SOFT.C will be displayed on the screen.
3 Pinch the soft contact lens with special tweezers to remove moisture from the lens. Put
the lens between paper and move three times to remove moisture from the surface.
4 If there is moisture dews on the surface when the contact lens is held to the light, put the
lens in the special solution again, and repeat the above. Moreover, take care about turning
inside out. When in the normal position, the lens looks like a bowl. However, when the
lens turns inside out, the rim looks warped. If the lens is ready for measurement, place it
on the contact lens holder and observe the shape (with tweezers) for alignment. After 30
seconds or more, the lens power changes since the internal moisture evaporates, there-
fore, measure it as quickly as possible.
A:STEP MODE
Select and press MODE button:
Press .
A soft contact lens cannot be accurately measured because of its structure.
Although you can measure a soft contact lens power in following way, consider the
results an average and not the exact value.
If there is moisture on the soft contact lens surface, it is not possible to measure
because the luminous flux malfunctions.
Use the hard contact mode when measuring a toric soft contact lens.
