Characterization of Contact Lens Plastics

作者: William E. Meyers ; Lyle M. Bowman ; Thomas B. Harvey

In the development of contact lens material, characterization of the materials includes measurement of gas transport, and mechanical properties, including the modulus of elasticity, tensile strength, percent elongation and tear strength. Physical properties determined on contact lens plastics include percent hydration, wetting angles, glass transition temperature, percent visible transmission, indentation hardness, refractive index, and percent linear expansion. In addition to polymer measurements, the protein and lipid deposition must be measured to determine biocompatibility in the eye. Each of the measurements must be performed on a finished contact lens which weighs 10 mg at a thickness 0.01 cm. This paper will describe how each of the listed measurements is performed on a contact lens and representative measurements will be given for contact lens polymers. This data will include both rigid gas permeable and hydrogel contact lenses.

Contact Lens Materials: Their Properties and Chemistries

作者: Thomas B. Harvey ; Lyle M. Bowman ; William B. Meyers

The use of poly(methyl methacrylate) (PMMA) in corneal contact lenses led to the popularization of the contact lens in the early 1950s. PMMA is lighter than glass, clear, rigid, and relatively inert biologically. Its largest failing as a contact lens material is its lack of oxygen permeability, and a variety of materials have since been developed to overcome the oxygen deprivation problem that arises with PMMA lenses. More modern contact lens materials have much higher oxygen permeability than PMMA, and most of these materials fall into one of two categories: (1) soft hydrogels, or (2) rigid gas permeable. The chemical compositions and physical properties of both types of materials will be discussed.

Contact Lens Manufacture and Function: Material Related Issues

作者: Lyle M. Bowman ; William E. Meyers ; Thomas B. Harvey

Every month, 4–5 new patents for contact lens materials appear in the international chemical literature. However, rarely do more than one or two new materials reach the market during the year. In addition, almost all new materials are minor variations of the basic lens polymers that have been available for the last 10 to 15 years. The problem which keeps the new materials from entering the marketplace is not a lack of demand for improved materials, but that most of the potential polymers satisfy only one or two of the requirements for clinical success. This paper will discuss 20 aspects of lens polymers which must be considered by investigators hoping to bring their new polymer to the ophthalmic market.
