Laser Surgery TRIZ Cases
- Compact UV Light Delivery Optics for Ophthalmic Power Loss Reduction
Integrated UV LEDs, beam homogenization, and shared-objective imaging cut bulk, power loss, and maintenance in ophthalmic UV delivery.
- Compact UV Light Delivery Optics for Uniform LAL Adjustment
Integrated UV LEDs, beam homogenization, and compact imaging enable uniform LAL adjustment with lower optical loss, heat, and size.
- Corneal Post-Treatment Planning for Epithelial Thickness Changes
Accounts for epithelial thickening after refractive eye surgery to improve incision positioning and complete lenticule extraction.
- Crystalline Lens Laser Patterning for Presbyopia Reversal
An annular laser pattern inside the crystalline lens boosts accommodation while avoiding capsule and pillar damage in presbyopia treatment.
- Ophthalmic Microscope Filtering for Vitreous Floater Visualization
Crossed polarizers and spectral filtering suppress Purkinje and retinal red reflections, making vitreous floaters easier to target with a laser.
- Eye Opacity Distance Measurement for Safe Laser Treatment
Retinal spot spacing and an eye model are used to locate floaters relative to the lens and retina before laser treatment.
- Bleb Formation Wire Loop for Single-Puncture Glaucoma Surgery
A deployable wire loop disrupts and cauterizes ocular tissue through one puncture, reducing tool changes, bleeding, and procedure time.
- Ophthalmic Laser Scan Path Compensation for Eye Tilted Incisions
A transformed curved scan path compensates for eye tilt, preserving precise symmetrical laser incisions without slowing treatment.
- Corneal Cross-Linking Illumination Tracking for Eye Movement Compensation
A spatial light modulator shifts pixelated corneal illumination with eye motion to keep cross-linking uniform and treatment precise.
- Shared-Aperture Eye Floater Laser Targeting With Real-Time Visualization
Real-time viewing and shared-aperture beam guidance help target vitreous floaters precisely while reducing collateral damage during laser treatment.
- Corneal Procedure Advisor for Topography-Based Astigmatism Compensation
Calculates topographic and astigmatism vectors to improve excimer laser treatment recommendations and avoid under- or overcorrection.
- Corneal Lenticule Cutting Pattern and Holder for Thin Implant Handling
A layered femtosecond laser cutting pattern boosts lenticule yield from one donor cornea while a flattened holder prevents thin implants from rolling or folding.
- OCDR-Guided Laser Vitreolysis for Precise Floater Targeting
Real-time OCDR localization guides laser focus onto vitreous floaters, improving targeting while reducing retinal and eye-structure risk.
- Push-Pull Fiber Connector Clocking for Multi-Core Laser Alignment
A tapered cam slot, clocking key, and sleeve align multi-core fibers to laser spots within about 10 microns for better coupling and power uniformity.
- Eye Mask Light Delivery for Precise Ciliary Body Treatment
A broad-area light source and opaque eye mask with transparent openings target the ciliary body without complex laser alignment.
- Pupil-Aware Eye Tracking with Local Dimming for Retina Safety
Local dimming cuts light through the pupil while boosting non-pupil illumination to improve eye tracking SNR and reduce retina risk.
- Ophthalmic Working Tip With Passive Aspiration to Cut Instrument Exchanges
A vented working tip passively aspirates intraocular fluid, reducing instrument exchanges, ocular trauma, and surgery time.
- Ophthalmic Laser Interface Grip for Stable Lens Cone Alignment
Soft elastomer on the lens cone and toothed gripper jaws increase coupling security, limiting eye movement and misalignment during laser surgery.
- MEMS Ophthalmic Laser Scanning for Compact Multi-Spot Treatment
A MEMS mirror, diode laser, and mobile control cut the size and cost of multi-spot retinal treatment while fitting existing slit-lamps.
