Intraocular Lens TRIZ Cases

Pressure-triggered latent heat accumulator warms intraocular lenses, eliminating battery weight and electrical contact failures.

Modifying major surfaces with Cartesian coordinates reduces base out prism in progressive addition lenses, minimizing eye strain from excessive convergence.

An automated folding mechanism handles complex hollow base geometries, eliminating manual handling risks and contamination during delivery.

A variable focus intraocular lens couples the optic to haptics at a non-zero flexion angle to center and fixate the device within the capsular bag.

Dynamic spring arms engage external threads for screw mode while disengaging for push action, eliminating complex manual switching mechanisms.

An intraocular lens with an outer support structure and weakened regions enables angular motion between components.

A posterior protrusion on an asymmetric intraocular lens restricts epithelial cell migration, preventing secondary cataract formation and dysphotopsia.

Customized intraocular lenses optimize near vision by tailoring optical add power to individual ocular biometry and reading distance.

Pillar fluidic actuators deform an optical surface layer, resolving the trade-off between complex configurability and adjustment precision in ophthalmic lenses.

Copolymerizing benzhydryl methacrylate monomers with cross-linking agents yields ophthalmic device materials.

Segmented lens haptics resolve slow recovery time by combining flexible and stiff segments for rapid focusing.

Central and lateral protrusions deform the intraocular lens into a mountain fold, preventing counterturn during capsule placement.

A holder with restriction members secures an intraocular lens storage part, preventing breakage from impact while maintaining sterilization for ready injection.

A variable focus intraocular lens employs simultaneous lateral and axial movement of optical elements to adjust focal power.
