Unisil was developed following feedback from leading eye care practitioners, who shared their desire for a wider range of silicone hydrogel options to meet the needs of their custom soft lens patients.

Unisil offers outstanding surface wettability, and the increased oxygen permeability of a silicone hydrogel, combined with a higher modulus to enable more complex lens designs, improving visual acuity and supporting corneal health.

Features and benefits

  • Higher oxygen permeability (50 Dk)
  • Increased modulus of elasticity (0.80 MPa)
