Laser Surgery TRIZ Cases

Segmenting the housing tube into distinct stiffness zones resolves the trade-off between structural stability and steerability in ophthalmic procedures.

Femtosecond laser pulses create gradient index layers within polymeric intraocular lenses to adjust refractive power.

A femtosecond laser control system adjusts pulse energy based on local tissue scattering and absorption properties.

A phacoemulsification system applies laser energy to clear aspiration tube blockages while maintaining optimal vacuum levels.

Multi-sectional light imaging reconstructs three-dimensional eye geometry to resolve lens tilt measurement errors in laser surgery.

Measured pulse characteristics compensate for biodynamic effects, reducing residual structures and correcting high-order aberrations in refractive treatments.

A computational system predicts post-operative iris color by measuring patient anatomical features and comparing them against a reference database.

A control device manages pulsed laser shot sequences to generate overlapping cavitation bubbles for precise corneal tissue separation.

Rotating prisms or vibrating mirror membranes move the focal spot across the fiber core, eliminating inter-mode interference patterns in short surgical fibers.

Rotating mirror set module guides femtosecond laser pulses through a two-dimensional XY scanner to create precise corneal ablation patterns.

Temporally offset diffracted pulses create cumulative photo-disruption while limiting cavitation bubble expansion that corrupts incision precision.

A multi-laser eye tracking system scans light across a region of interest using sequentially activated semiconductor chips to increase dwell time.
