Thermal Processing for the Ophthalmic Industry

Ophthalmic

Thermal processing is a quality-critical step in the production of contact lenses and intraocular lenses. As the market leader for thermal processing in the ophthalmic industry, we plan, develop, and produce customized industrial ovens and oven systems for all thermal processing needs. The most important products of the ophthalmic industry include intraocular lenses (IoL) and contact lenses. Thermal processing is mostly involved in the production of both types of lenses. Depending on the production method adopted, these products are mostly subjected to thermal processing for either curing or sterilization. Curing for instance is commonly used in the production of molded intraocular lenses. In this process, the mold is heated beyond the phase of transition, held at a certain temperature long enough to achieve uniform heating. In the process, the chemical properties of the monomer(s) are processed to achieve specific results. A similar process is used in the production of contact lenses.

Weiss Technik’s thermal processing solutions are engineered to meet the most stringent requirements of the ophthalmic industry. Whether it’s curing molded intraocular lenses or processing contact lenses, our technology ensures precise temperature control and uniform heating. We adapt to each manufacturer’s specific requirements, with maximum temperature deviation customized to exact specifications.

Our industrial heating technology meet standards such as:

  • FDA 21 CFR part 11
  • EN 1539
  • UL Standards
