Intraocular Lens TRIZ Cases

An intraocular lens moves within an inner capsular bag to adjust focus via gravity.

Stiffer haptic protrudes into optic recess to transmit force, resolving low accommodation range in intraocular lenses.

Peripheral lugs extend from the optic to engage capsule voids, resolving X-Y centering and rotational placement inaccuracies.

Segmented intraocular lens parts shift toward each other under capsular bag tension, generating restoring force to restore accommodation.

Coplanar haptic compression eliminates manual surgeon manipulation during implantation, reducing surgical trauma and placement errors.

A foldable intraocular lens uses a step edge haptic to stabilize the optic and prevent cell migration.

A segmented system controller manages variable-focus optics in ophthalmic lenses using digital logic state machines to minimize power consumption.

An elastic intraocular lens restores accommodation by changing curvature through ciliary muscle traction, avoiding capsular fibrosis.

A polydimethylsiloxane monomer incorporates phosphorylcholine and hydroxyl groups to enhance compatibility with hydrophilic components.

Segmented intraocular lenses image onto distinct macula regions to resolve narrow visual fields and halos from conventional aids.

A modular intraocular implant features a fenestrated flange to retain interchangeable optics within the eye.

Superposed diffractive profiles on an intraocular lens create distinct focal points, reducing light loss to higher orders while maintaining contrast.

An aspheric toric intraocular lens combines toricity and asphericity on separate or single surfaces to correct optical aberrations.

An eye-tracker adjusts a superimposed pattern on the microscope image to maintain alignment with moving eyeballs during corneal transplant surgery.

A diagnostic instrument registers eye structure data to generate structural images with positional markings.

A 360-degree haptic plate limits vitreous bulging and reduces capsular herniation.

A truncated cone back surface on an intraocular lens increases posterior capsule contact area for improved intracapsular stability.

Posterior haptic step features create barrier angles that prevent epithelial cell migration and minimize anterior vaulting of intraocular lenses.

Flexible haptics drive ridges into an artificial intraocular lens edge, merging magnification with standard vision correction for AMD patients.

A rotatable dial mechanism folds an intraocular lens and releases the cartridge from packaging upon withdrawal.

Corrugated haptics anchor intraocular lenses through mechanical interlocking, eliminating iris damage while maintaining aqueous humor flow.

Hydraulic pressure drives a plunger to deliver fluid-filled intraocular lenses, reducing device complexity and minimizing working fluid volume.

A light adjustable lens uses laterally offset axes to enable post-operative optical power adjustment through photopolymerization.

Convex slot curvature guides haptic folding to prevent optic damage during small incision insertion.

Segmented flexible haptics adapt to varying ciliary sulcus sizes, maintaining safe distance from the natural lens and preventing inflammation.

Elastic deformation of the inner lens core alters surface curvature to restore near vision focus.

A biased accommodating intraocular lens couples a lens optic to a plate haptic for dynamic anterior movement.

Segmented capsular rings maintain bag shape and enable accommodation.

A rotating nosepiece transfers an intraocular lens from a sterile case, resolving sterility and orientation challenges during loading.

Segmented intraocular lenses enable optic exchange and accommodation while the porous retainer prevents fibrous in-growth.
