• PMMA corneal lenses became the first CLs to have mass appeal through the 1960s, as lens designs became more sophisticated with improving manufacturing ( lathe ) technology.
• Isseroff and Schwab recently decided to try growing their corneal lenses in a protein mix that the Sacramento biotech firm Thermogenesis is testing as a wound-sealing compound.
• Regardless of the lens size, it is thought that the larger the RGP lens will in most cases be more comfortable then standard rigid corneal lenses, and at times more comfortable than soft lenses, regardless of the fact that it is a rigid lens.
