WÖHLK S BTK (bitoric-compensated)
The new, simply called WÖHLK, gas permeable hard lens is manufactured in a variety of different materials and spherical back surface shapes. It can be individually adapted to the customer's specific corneal shape and tear film situation.
The BTK design is used for toric corneas and improves the lens fit...
Please order this type of lens only 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.
