Laser Surgery TRIZ Cases
- Corneal Cross-Linking Systems With Photochemical Kinetic Control
A photochemical kinetic controller models oxygen and non-oxygen reactions to adjust light parameters for precise corneal cross-linking.
- OCT-Guided Photocoagulation for Deep Retinal Tissue Monitoring
OCT imaging compares retinal scans before and after treatment to reveal deep tissue changes during subthreshold photocoagulation.
- Multi-Wavelength Photocoagulation Laser With Shared Aiming Path
Switch among four photocoagulation wavelengths in one device while selective lenses keep the 635 nm red aiming light aligned.
- Micro-Abrasion for Corneal Cross-Linking Agent Delivery
Micro-abrasion opens temporary epithelial pathways for topical agent delivery while limiting deeper tissue disruption.
- Collagen-Binding Particle Composition for Vitreous Floater Treatment
Collagen-binding particles move through the vitreous, bind floaters, and form laser-triggered nanobubbles for targeted breakup.
- Ophthalmic Laser Lens Cone Cap for Precise Installation
Frustoconical lens cones can be difficult to align and grip; a ribbed cap, snap fit, and bayonet mount support precise installation.
- OCDR-Based Focus Recalibration for Intraocular Laser Treatment
OCDR depth profiles guide laser focus recalibration against target eye structures, reducing misalignment risk during intraocular treatment.
- Central-Peripheral Corneal Ablation for Presbyopia Correction
Zoned treatment creates a central near-vision protrusion and peripheral emmetropia, avoiding multifocal optical overlap.
- Capsulotomy Cutting Ring Geometry for Uniform Current and Temperature
Slotted tabs and compensating ring features balance current density and temperature, preventing hot and cold spots during micropulse tissue cutting.
- Direct-Diode Adapter for Compact Photothermal Ophthalmic Treatment
Bulky laser systems and external fiber cables complicate eye treatment; an integrated direct-diode adapter simplifies retrofit deployment.
- Contactless Tonometer Using Eye Curvature for Surgical IOP Monitoring
During cataract surgery, cameras infer IOP from eye-surface curvature for continuous, contactless monitoring and threshold-based safety alerts.
- Ray-Traced Customized Corneal Ablation for Precise Ametropia Correction
Ray tracing combines anterior and posterior corneal topography with refractive data to limit tissue removal during ametropia correction.
- Laser Surgical Corneal Marker Tracking for Eye Alignment
Camera tracking of a laser-created corneal marker detects eye movement and alerts operators when treatment-pattern alignment shifts.
- Eye Movement Tracking With Alert-Point Feedback
Alert points and visual or auditory feedback help keep the eye inside its tracking range, reducing false positives and interruptions.
- Corneal Laser Parameter Optimization Using Post-Operative Feedback
Inconsistent corneal surgery algorithms are refined with autorefractor data and post-operative refraction feedback to personalize laser settings.
- Patient Interface Device for Laser–Phacoemulsification Without Repositioning
An integrated patient interface coordinates laser delivery and phacoemulsification to shorten procedures and avoid patient repositioning.
- Intraocular Lens Refractive Index Writing for Photic Phenomena
Focused laser pulses modify an implanted IOL's refractive index to offset halos, glare, and starbursts without lens replacement.
- Combined Excimer Laser and Phacoemulsification for Glaucoma Drainage
A combined eye-treatment unit uses excimer laser perforations and phacoemulsification through one incision to improve drainage and lower intraocular pressure.
- Sub-Nanosecond Laser Surgery With Dual-Energy Pulsed Beams
One laser source alternates higher- and lower-energy sub-nanosecond pulses to create precise incisions across different intraocular targets with less tissue damage.
