Ophthalmics

The production of ophthalmic products including contact lenses, solutions for cleaning and storing contact lenses and solutions for flushing as well as eye treatment products must meet the strictest requirements and specifications for particle and microbial control in order to assure product quality and user safety. Filtration is a significant part of product quality management and the various processes can present notable challenges for a manufacturer. A main component of the most ophthalmic solutions is water which requires a series of high purity processing steps. The various ingredients such as sodium chloride, protective substances, various polymers, viscosity enhancers and the polymer used for the lenses all require careful optimization to ensure cost effective and consistent products and processes.
