ASCON VPT ( anterior prismatic-toric )
Hard gas permeable, individually manufactured contact lens.
The ASCON®-VPT has a rotationally symmetrical back surface in ASCON® design and a toric front surface. An additional prism prevents the rotation of the contact lens on the eye.
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.
