Paper Abstract

In phase one of the program, three surface abrading techniques were evaluated for variability within sample sets and between test laboratory sites using lenses prepared from allyl resin homopolymer. Phase two of the program, assessed the ability of each machine-type to rank the performance of three commercially available lens coatings versus uncoated lenses.
