BIAS BTX ( bitoric crossed )
Hard gas-permeable, individually manufactured contact lens with UV filter.
The BIAS®-BTX has a toric back surface in the BIAS® design, combined with a toric front surface. The special feature of the BIAS®-BTX is that the main cuts of the back surface and those of the front surface are oblique to each other.
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.
