High-Purity Monomers & Polymers for Ophthalmic Applications

The development and manufacture of contact and intraocular lenses requires a dependable supply of innovative, reliable raw materials including polymers and reagents. New materials can help enhance oxygen and water permeability, providing increased comfort and safety to contact lens wearers.

Monomer selection impacts a number of lens attributes such as modulus, permeability, surface smoothness, UV radiation absorption and resistance to tearing and surface defects.

We offer a wide and growing selection of monomers and polymers for ophthalmic applications, along with a full range of initiators, crosslinkers, dyes, and solvents. Our broad selection is backed by known quality levels and outstanding service, enabling contact lens manufacturers to quickly and successfully develop revolutionary new products.

From Research to Commercial Scale Manufacturing – Your Monomer Expert

We have extensive expertise in helping to the right products and process to scale up your production. As a global manufacturer and supplier of ophthalmic materials we can ensure you have a continuous supply of your critical reagents.

Custom capabilities to keep your project on track

If a monomer of interest is not on this product list, or if you have a unique requirement, we invite you to take advantage of our extensive custom manufacturing capabilities. Our state-of-the-art facilities enable us to provide customized support from process development through scale-up and production. We offer a variety of services including multi-step organic synthesis, handling of air-sensitive compounds and high-efficiency flow chemistry. Whatever your specific needs may be, your manufacturing program will be managed by an experienced dedicated project team that will ensure timely and cost-effective completion.

Examples of specialty monomers on manufacturing scale:

  • 3-[Tris(trimethylsiloxy)silyl]propyl vinyl carbamate
  • 3-(Trimethoxysilyl)propyl vinyl carbamate
  • N-(3-Aminopropyl)methacrylamide hydrochloride
  • (3-Acrylamidopropyl)trimethylammonium chloride
  • 2-Hydroxyethyl acrylate
  • N-Diphenylmethylacrylamide

Choosing raw materials with clear quality expectations

Reagents and raw materials come with predetermined levels of quality documentation. Our documentation and change notification support is structured around our M-Clarity™ Program. The Quality Segments of the M-Clarity Program provide transparency so that you can choose, with confidence, suitable products that meet your needs with respect to:

  • Compliance with the appropriate quality and regulatory standards
  • Portfolio transparency
  • Change notification service
  • Documentation and support
