Title: Innovations of William L Sturm
Introduction
William L Sturm is a notable inventor based in Calgary, Canada. He has made significant contributions to the field of ocular lens technology. With a total of 3 patents to his name, Sturm's work focuses on enhancing the performance and characteristics of gas permeable ocular lenses.
Latest Patents
One of Sturm's latest patents is for an ocular lens composition and method of formation. This invention discloses a gas permeable (GP) ocular lens composition that combines 98-70% by weight of a first polymer component, selected for its gas permeability, with 2-30% by weight of a second polymer component, chosen for its rigidity and structural stability. The resulting interpenetrating polymer network (IPN) structure forms a thermoplastic composition that exhibits optical clarity and compatibility. This innovation facilitates low-cost formation through molding or thermoforming techniques. The lens composition boasts a flexure modulus ranging from about 2,000-50,000 psi, with preferred values between 5,000-40,000 psi, and more ideally between 20,000-40,000 psi. In one embodiment, the lens features a central portion and an annular portion with different characteristics. Additionally, a cosmetic version of the lens encapsulates a film with an image of an iris.
