ASCON RT ( back surface toric )
Hard gas permeable custom contact lens.
The ASCON®-RT has a toric back surface in the ASCON® design, combined with a spherical front surface. It is fully corrective when the induced astigmatism is corrected by the internal astigmatism.
Please only order this type of lens if you are already wearing it successfully.
It will be made individually for you. Exchanges, cancellations or returns, even if the contact lens is in perfect condition, are excluded.
