Title: Innovations by Richard Govan in Contact Lens Technology
Introduction
Richard Govan is an accomplished inventor based in Fairburn, GA (US), known for his significant contributions to the field of contact lens technology. With a total of two patents to his name, Govan has focused on developing methods that enhance the performance and usability of silicone hydrogel contact lenses.
Latest Patents
Govan's latest patents include a method for making coated silicone hydrogel contact lenses. This invention relates to a process for producing contact lenses that feature a hydrogel coating, which provides a high resistance to the uptake of polycationic antimicrobials. The method involves covalently attaching a hydrophilic polymeric material onto a base coating of a polyanionic polymer on a silicone hydrogel contact lens. By utilizing a rinse solution with a higher pH and/or higher ionic strength, Govan's method achieves a lower polyquaternium-1 uptake of less than 0.40 micrograms per lens.
Another notable patent is the method for producing MPS-compatible water gradient contact lenses. This invention outlines a process for creating contact lenses that not only possess a water gradient structural configuration but also minimize the uptake of polyquaternium-1. The lenses maintain long-lasting surface hydrophilicity and wettability, even after undergoing a simulated 30-day lens care regime.
