This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,392.

Summary of the Inventive Concept

This inventive concept adapts multifocal intraocular lenses for specific, narrow markets or unique operational environments, such as high-security needs, disaster relief, or extreme weather conditions.

Background and Problem Solved

The original multifocal intraocular lens patent addressed the limitations of existing IOLs in providing clear vision and independence from eyeglasses. However, these lenses were not designed to operate in specialized environments, which posed unique challenges to their performance. The present inventive concept solves this problem by introducing adaptations to the original design to cater to these specific environments.

Detailed Description of the Inventive Concept

The inventive concept comprises a family of multifocal intraocular lenses, each tailored to a specific environment or application. For high-security environments, an additional diffractive order provides a high-contrast image focal point for surveillance purposes. In disaster relief scenarios, an asymmetrical diffractive profile enables the lens to operate effectively in extreme weather conditions. For high-altitude environments, a variable thickness and constant curvature ensure clear vision at high elevations. Additionally, the inventive concept includes a method for customizing the lens to a specific user's occupation and environmental conditions.

Novelty and Inventive Step

The novelty of the present inventive concept lies in its adaptation of the original multifocal intraocular lens design to specific, narrow markets or unique operational environments. The inventive step is the introduction of specialized features, such as additional diffractive orders, asymmetrical diffractive profiles, and variable thickness, to address the unique challenges of these environments.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include lenses with adjustable diffractive orders, dynamic curvature adjustment, or integrated sensors to monitor environmental conditions. Variations could also include lenses designed for specific occupations, such as pilots or miners, or for use in extreme temperatures.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential in various industries, including high-security surveillance, disaster relief, aerospace, and occupational health. The target market includes government agencies, disaster relief organizations, and companies operating in extreme environments.
