Electro-Active Intraocular Lens for Dynamic Focus and Aberration Correction

The patent applies dynamics by making the intraocular lens adjustable and adaptable rather than static. The lens can change its optical properties (refractive power, prism power, tinting) in response to ciliary body signals or external control, enabling it to accommodate focus dynamically similar to the natural crystalline lens. This resolves the contradiction by providing both adaptability through dynamic adjustment and reliability through controlled, predictable optical changes.

The patent utilizes parameter changes by varying the refractive index, curvature, or position of the lens elements to achieve different focal lengths and optical corrections. The electro-active or shape-memory materials allow the lens to change its physical parameters in response to stimuli, enabling accommodation and correction of multiple refractive errors simultaneously, thus improving both adaptability and visual performance.

The patent applies segmentation by dividing the intraocular lens into multiple independently controllable zones or regions, each capable of performing different optical functions (e.g., distance focus, near focus, prism correction, tinting). This allows the lens to correct multiple visual conditions simultaneously while maintaining a relatively simple overall structure, as each zone can be controlled independently through a unified control system.

The patent implements multi-functionality by designing a single intraocular lens that can perform multiple visual correction functions (accommodation, prism correction, aberration correction, tinting) within one device. This universal approach improves vision correction capability across multiple conditions while avoiding the need for multiple separate surgical implants, thereby managing device complexity.

The patent applies feedback by incorporating sensors that detect ciliary body contraction, eye position, or visual demands and automatically adjust the lens parameters in response. This feedback mechanism enables post-surgical tuning and adaptation to changing eye conditions without requiring complex external control systems, as the lens self-regulates based on physiological signals from the eye itself.

The patent implements self-service by designing the intraocular lens to automatically adjust its optical properties in response to physiological signals from the patient's own ciliary body or other eye structures. This eliminates the need for external power sources or complex control electronics, reducing device complexity while maintaining high post-surgical adaptability through biologically-driven adjustment.
