Solution Overview

Problem

There is a long-standing need to address presbyopia, restore the ability to simultaneously have good near and far vision in older patients, and replace the need for bifocals by improving the optical system of the eye.

Innovation Solution

A laser system is used to deliver a laser beam pattern to the natural crystalline lens, creating an annular shape-changing zone within the lens without affecting the anterior and equatorial pillars, thereby enhancing the amplitude of accommodation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If laser beam is delivered to the lens to create shape-changing zone, then amplitude of accommodation is increased, but lens capsule and structural pillars may be damaged

Engineering Contradiction:

Improveamplitude of accommodationVSAvoidlens capsule integrity

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The laser beam is delivered in a controlled pattern that creates shape-changing zones in specific regions of the lens while deliberately avoiding the lens capsule and structural pillars. This localized treatment allows accommodation improvement without compromising the structural integrity of critical lens components.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The laser treatment pattern is segmented into multiple discrete zones within the lens, creating a distributed network of shape-changing regions. This segmentation allows the treatment to achieve cumulative accommodation effects while maintaining safe distances from the lens capsule and pillars through controlled beam positioning.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If laser beam pattern is delivered entirely within the lens, then accommodation improvement is achieved, but lens capsule remains unaffected

Engineering Contradiction:

Improveamplitude of accommodationVSAvoidtreatment precision

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The system replaces mechanical contact methods with a non-contact laser beam delivery system. The laser beam is precisely positioned and focused within the lens using optical guidance and control systems, eliminating the need for physical instruments that could damage the lens capsule while achieving the same therapeutic effect.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The laser beam acts as an intermediary energy carrier that can be precisely directed and controlled to create shape-changing zones within the lens. The beam's energy is absorbed by the lens material to induce localized structural changes without requiring physical contact with the lens capsule, thereby improving safety and precision.

Inventive Principle:

Principle #24Intermediary (Mediator)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case
