Unisil
Unisil is Contamac’s latest silicone hydrogel material, developed specifically to add greater versatility to your soft contact lens portfolio via its finely-tuned and balanced blend of monomers. Unisil’s unique polymer matrix provides outstanding surface wettability, visual acuity, and a higher Dk than conventional hydrogels to improve corneal health. The result is a material offering superior levels of stability and reproducibility. Unisil also has a Class II UV blocker as standard to satisfy the demands of daily wear and daily life.
Unisil is dimensionally stable making it ideal for a wide range of multi-pack modalities.
