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

A novel multifocal intraocular lens design that combines optimized refractive-diffractive surfaces to minimize aberrations and improve visual acuity at multiple focal lengths, providing improved visual performance and reduced dependence on pupil size.

Background and Problem Solved

The original multifocal intraocular lens patent (Multifocal intraocular lens) has limitations in terms of visual performance and pupil dependence. The new inventive concept addresses these limitations by introducing an optimized refractive-diffractive structure that reduces aberrations and improves visual acuity, enabling better visual outcomes for patients.

Detailed Description of the Inventive Concept

The enhanced multifocal intraocular lens features a refractive-diffractive structure optimized using machine learning algorithms to minimize aberrations and improve visual acuity at multiple focal lengths. The lens is fabricated using 3D printing techniques, allowing for precise control over the diffractive profile. Additionally, the lens may include an anti-reflective coating to reduce glare and improve visual comfort. A software module analyzes the patient's visual preferences and prescription, and a manufacturing module fabricates a customized lens based on the analysis.

Novelty and Inventive Step

The new claims introduce an optimized refractive-diffractive structure, which is a novel and non-obvious improvement over the original patent. The use of machine learning algorithms to optimize the diffractive profile and the incorporation of 3D printing techniques for fabrication are also innovative aspects of the new inventive concept.

Alternative Embodiments and Variations

Alternative embodiments of the enhanced multifocal intraocular lens could include varying the refractive-diffractive structure to accommodate different patient populations or using different materials for the lens. Additionally, the software module could be modified to incorporate additional patient data or preferences.

Potential Commercial Applications and Market

The enhanced multifocal intraocular lens has significant commercial potential in the ophthalmic industry, particularly in the areas of cataract and refractive surgery. The ability to provide improved visual performance and reduced dependence on pupil size could lead to increased adoption and market share.
