Implant coatings may change contact lens design

Implant coatings may change contact lens design

New research has revealed that it may be possible to permanently bind antibacterial coatings to medical devices - a development which may affect the contact lens industry.

According to experts at University of South Australia, this can be achieved through first binding the coatings them to a polymer layer, and could have ramifications for the development of orthopedic implants and catheters, as well as contact lenses.

Hans Griesser from the University of South Australia, an author of the report, said that no solution is universal so it is important to establish an array of approaches.

"The new diterpene compounds that we are testing are structurally quite different from established antibacterial compounds, and they are effective against methicillin-resistant Staphylococcus aureus. That is what got us excited about them," he explained.

In other research, specialists at St Andrews University recently developed a new technique which involves separating the meta-atoms from the substrate they are constructed on and stacking them together to create a flexible material.

Called Meta-flex, the material is almost invisible and could lead to the perfect contact lens, the experts claim.
