Intraocular Lens TRIZ Cases
- Accommodating Intraocular Lens Ring for Wider Dioptric Adjustment
A ring with radially spaced haptics shifts an IOL along the optical axis to expand dioptric range, improve near vision, and lower capsule risk.
- Intraocular Lens Haptic Geometry for Uniform Capsular Force
A tapered haptic with a thickening gusset and thinning distal region spreads capsular bag force more evenly, reducing striae while preserving IOL stability.
- Multifocal Intraocular Lens Zoning to Minimize Glare and Halos
Three optic zones and a transition zone deliver near, intermediate, and distance vision while reducing glare, halos, and light loss.
- Intraocular Lens Haptic Alignment Using Splay Arms
Active splay arms and plungers straighten intraocular lens haptics before insertion to limit rotation and improve placement accuracy.
- Intraocular Lens Injector Packaging for Stress-Free Storage
A two-state injector package keeps the intraocular lens unfolded during storage, then enables simple preparation and insertion when needed.
- Shape-Changing Intraocular Lens Optics for Lost Capsular Elasticity
Radial tension reshapes an intraocular lens optic to restore accommodative power even when capsular elasticity is reduced by fibrosis.
- Accommodating Intraocular Lens Layout for Small-Incision Implantation
A segmented passive and electro-active IOL layout enables small-incision implantation while preserving clear vision during power failure.
- IOL Cartridge Packaging Lock With Dial-Guided Lens Folding
A dial-folded IOL cartridge stays locked in packaging until rotation, simplifying unpacking, handpiece attachment, and accurate lens delivery.
- Magnetic IOL Haptic Positioning for Reliable Injector Insertion
Magnetically retracting intraocular lens haptics in the injector enables compact insertion and controlled unfolding with lower risk of damage.
- Fluid-Actuated Intraocular Lens Centering After Capsular Bag Insertion
Adjustable fluid reservoirs and haptics recenter an intraocular lens after insertion, reducing aberrations without added surgery.
- Hybrid Implant Delivery Drive for Small-Incision Lens Insertion
A hybrid plunger and hydraulic drive delivers intraocular implants through small incisions with lower actuation force and steadier control.
- Adjustable Intraocular Lens Haptics for Non-Invasive Repositioning
Electromagnetic radiation changes haptic and brace arm curvature to reposition an intraocular lens in the capsular bag without surgery.
- Intraocular Lens Injector With Sealed Folding Chamber
A sealed folding chamber stores the IOL in fluid while keeping injector surfaces dry, reducing contamination risk and preserving coating stability.
- Modular Intraocular Lens Assembly for In-Place Refractive Adjustment
A base-and-tab lens assembly allows refractive correction changes after implantation without disturbing the capsular bag.
- Asymmetric Intraocular Lens Haptics for Stable Capsular Fixation
Unequal haptic arm lengths distribute restoring force more evenly, limiting IOL rotation, deformation, and capsular bag stress.
- Modular Intraocular Lens Ring Geometry for Off-Axis Glare
A non-parallel flange on a modular IOL ring defocuses off-axis light to reduce glare artifacts while enabling smaller implantation incisions.
- Metasurface Intraocular Lens for Reducing Positive Dysphotopsia
Sub-wavelength metasurfaces on IOL surfaces cut visible reflections and glare, reducing positive dysphotopsia after implantation.
