Intraocular Lens TRIZ Cases

A removable cap engages the cartridge slide to fold an IOL in sequence, reducing manual steps and user errors during delivery.

A two-cell controller balances sustained movement and peak delivery power, while a hollow plunger uses hydraulics to reduce force through small incisions.

A peripheral implant blocks oblique light in the iris-lens gap, reducing negative and positive dysphotopsia while preserving central vision.

Phase-shift regions align focal positions across wavelengths, reducing chromatic aberration by up to 0.5 diopters.

This case uses a lens support structure and fixation arms to stabilize IOLs without sutures or direct corneal contact.

This case uses a separate base and optic with haptics to stabilize the IOL in the capsular bag and maintain refractive correction.

A standardized connecting support secures varied haptic parts, stabilizing lens position while transmitting capsular forces.

This lens uses zonal and phase-shift structures with a transition region to extend intermediate depth of focus without visual disturbances.

A heat-sensitive reservoir moves optical fluid through a flexible IOL, enabling reversible, noninvasive base-power adjustment.

Alternating sawtooth structures create multiple focal points while simplifying manufacturing and reducing light scattering.

This case combines roughness-patterned haptics with laser-responsive material for post-operative IOL power adjustment without added surgery.

Flexible footplates stabilize phakic IOLs while manipulation pockets ease implantation.

This case uses a radial recess and nested reservoir attachment to limit detachment and decentration during intraocular lens implantation.
