Abstract

The Polycon II and Paraperm 02 contact lens were compared using a contralateral eye study protocol. Both materials are rendered gas permeable by virtue of PMMA-Silicone copolymer. Each has recently received FDA approval. The lenses were compared with respect to manufacturing accuracy, stability of parameters, lens wetting, subjective and objective assessment and their impact on central corneal thickness. There was no statistically significant difference found between the two lenses in any of the above categories. However, non-statistical observation of the results repeatedly suggest that the Polycon II may be a marginally preferable material to utilize at present.
