Optimum Infinite

Optimum Infinite is a gas permeable (GP) material with a unique combination of oxygen permeability and flexural modulus. Optimum Infinite has a hyper oxygen permeability value of 180Dk and a high flexural modulus of 1341MPa, defying the high-Dk-low-flexural modulus convention. This breakthrough was motivated by the requirements raised for a dedicated scleral material at several laboratory panel and Key Opinion Leader meetings. Optimum Infinite is FDA cleared for a broad range of indications and its excellent surface wettability can be further enhanced through the use of Tangible Hydra-PEG coating.
