Purpose: This study investigated the effect of DPDMS on the oxygen permeability of contact lenses.
Methods: The functional silicone monomers MPDMS [poly (dimethylsiloxane) methacrylate modified] were used and the hydrophilic monomers amino substituted methacrylate and HEMA (2-Hydroxyethyl methacrylate) were polymerized in proportions.
Results: Oxgen transmissibility was measured in the range of 8.158 to 20.389 x 10-9 (cm/sec)( mlO2/ml x mmHg), and the oxygen permeability was measured in the range of 37.511 to 75.691 x 10-11(cm2/sec)(mlO2/ml x mmHg). As the addition ratio of MPDMS increased, the oxygen permeability increased.
Conclusions: MPDMS is considered to be useful as a highly oxygen permeable contact lens material.
