Laser Surgery TRIZ Cases
- Ophthalmic Surgical Probe With Beveled Oval Aspiration Port
A beveled distal tip and oval aspiration port improve vacuum generation while limiting probe gauge and retinal damage risk.
- Ophthalmic Laser Swivel Arm Housing for Protected Fixed-Position Treatment
Coaxial pivoting of the laser arm and housing protects optics and supports compact treatment without patient repositioning.
- Eye Surgical Laser Lenticule Compensation for Corneal Deformation
Compensate corneal deformation to improve eye-laser lenticule separation accuracy.
- Iris Imaging and Laser Tracking for Precise Eye Color Alteration
This case maps local iris absorption and tracks tilt to guide scanned laser delivery for selective stromal pigment removal.
- Ophthalmic Laser Pulse Compensation for Corneal Interference
This ophthalmic surgical case detects interfering objects in real time and adapts laser pulse delivery to preserve corneal ablation precision.
- Ablatable Corneal Inlay With Cross-Linking for Presbyopia Correction
A darkened annular inlay is laser-ablated for vision correction, while photo-cross-linking strengthens tissue and limits immune rejection.
- Pneumatic Cross-Connect Proportional Valve for Surge Control
This case uses pneumatic cross-connect pressure and vacuum control to clear aspiration clogs and reduce ocular fluid surges.
- Corneal Pocket Formation Using Variable Laser Scan Geometry
An electronic circuit varies scan speed and geometry to form precise corneal pockets for individualized surgical treatment.
- Ophthalmic Eye Modeling With Light-Propagation Focal Simulation
This ophthalmic system builds an eye model from measurements and displays simulated focal areas relative to the retinal plane.
- OCT-Based Laser Vitreolysis for Safe Deep Floater Targeting
OCT imaging maps floater depth and safe distances, enabling automated laser targeting with less retinal damage risk.
