Manny’s Tip from the Lab: Lens Wettability

One of the most important lens parameters is the material’s oxygen permeability or Dk value. Did you know that higher DK materials have a lower wettability? Patients with severe ocular surface disease may benefit from a lower Dk material and thus higher wettability. See below for BostonSight SCLERAL material options and their accompanying Dk value.

Remember that Hydra-PEG significantly improves lens wettability. Hydra-PEG coating can be added for a one-time additional fee of $25 per lens.

If you would like more information on selecting lens materials, please refer to this article from the Review of Contact Lenses.
