Upon completion of this program, the participant should be able to:
- To learn about the development of ophthalmic lens monomers and coatings
- To learn about lens casting and dip/spin coating.
- To see how a lens monomer is cast into a finished or semi-finished lens blank
- To learn how to communicate the performance benefits of ophthalmic lens materials to the patient
ECP's generally know the benefits of various materials and how they apply to a particular patient's Rx. Yet, we know little about the material science or engineering of ophthalmic lens monomers or lens casting in the production of finished or semi-finished lens blanks used in the making of eyeglasses. Most of us possess a natural curiosity to learn about the making of things, such as ophthalmic lenses. I admit to knowing little about the development of what PPG chemists humorously refer to as the "magic goop." They use this term to describe the chemical solution that is the base of the lens monomer or coating formulary used in casting and coating of ophthalmic lenses. After a tour of the R&D facility of PPG, I was both overwhelmed and impressed by the amount of research and development required to produce the magic goop as was I impressed by the casting process for lenses.
In this course, you will gain a new appreciation for the ophthalmic lens, both semi-finished and finished. You will learn about the chemistry of ophthalmic lens monomers and coating formularies for casting and coating. The next time you hold a PPG TRIVEX® material or PPG CR-39® material or the new PPG TRIBRID® material, lens blank in your hand, take a moment to be amazed. Please take a moment to ponder all of the planning, the R&D, the casting, the coating, and the marketing it takes to get that FDA Class 1 Medical Device into your hands and on the patient's face. As the patient's trusted ECP, your new appreciation and enthusiasm will transfer to the patient, raising their appreciation for the small but essential accessory that corrects their vision.
