Laser Surgery TRIZ Cases
- Automated Laser Eye Surgery Alignment via Image Processing
An automated laser eye-surgery system uses computer image processing to detect anatomical features and determine incision placement parameters.
- Semi-Meridian Corneal Astigmatism Vector Planning
Segmenting the cornea into independent semi-meridians resolves inconsistent astigmatism quantification by applying distinct vector parameters to each half.
- Corneal Incision Control via Focused Pulsed Laser
Focused pulsed laser radiation creates precise corneal incisions with controlled cross-sectional profiles.
- Laser Eye Treatment Monitoring via Cell Lysis Signal Analysis
Sequential laser pulses establish baseline signals to determine cell lysis, preventing over-treatment damage to surrounding tissues.
- Medical Applicator Integrating Shock Waves with Electrical and Light Therapy
An applicator couples mechanical pressure waves alongside electrical current, light, and ultrasound into tissue for simultaneous treatment.
- Laser Material Processing Overlapping Interaction Zones
A laser processing method aligns interaction zones to overlap within material layers using pulsed radiation.
- Scleral Lens With Central Virtual Pinhole For Keratoconus
A scleral lens features a central virtual pinhole with a darkened internal wall to provide stable vision correction.
- Red Light Photobiomodulation for Diabetic Retinopathy Treatment
Red light photobiomodulation replaces invasive injections to reduce oxidative stress and delay diabetic retinopathy progression.
- Laser Eye Treatment Calibration via Aberrometry Profilometry
Direct examination of ablated test bodies determines fluence and spot shape, resolving measurement precision trade-offs in laser eye treatment systems.
- Partial-Depth Ophthalmic Laser Incisions for Astigmatism Correction
Segmented laser cuts correct astigmatic aberrations without compromising tissue strength, resolving the precision-strength trade-off.
- Steerable Laser Probe Actuation Mechanism
An actuation structure curves a housing tube to steer an optic fiber, resolving the trade-off between structural stability and steering capability.
- Magnetic Contact Lens Anchoring for Ophthalmic Stability
A contact lens assembly uses magnetic anchoring to secure positioning during eye surgery.
- Laser Ablation System for Deep Sclerectomy
A laser ablation system creates a filtration pathway in scleral tissue without penetrating the eye.
- Ophthalmic Docking Decondenser for Contact Lens Clarity
A decondenser introduces dry gas to remove vapor condensation from an ophthalmic contact lens, preserving image precision during surgical alignment.
- Automated Retinal Laser Targeting Avoids Blood Vessels
Fundus camera imaging identifies blood vessels to guide automated laser targeting, reducing surgical time and labor intensity.
- SMILE Laser Planning Unit for Corneal Lenticule Access
A planning unit generates control data to establish precise cornea cutting planes including cap and lenticule cuts.
- Femtosecond Laser Ophthalmic System with 3D Scanning
A movable mirror switches between femtosecond laser exposure and confocal microscopy imaging.
- Photochemical Bonding for Intraocular Lens Stability
Photochemical bonding creates stable intraocular lens fixation without mechanical stress or uncontrolled fibrosis.
- Laser Capsulorrhexis for Stable Lens Positioning
Thermal denaturing of collagen via scanning laser beams eliminates errant tears and ensures precise intraocular lens alignment.
- Corneal Tissue Resection via Annular Sidecut Laser Incisions
Pulsed laser beams create annular and radial sidecut incisions in donor and recipient corneas for precise tissue resection.
- Dynamic Pneumatic Valve Driver for Surgical Console
A controller adjusts valve duty cycle using real-time pressure sensor feedback to balance pneumatic channels.
- Elongate Loop Lens Cutting Device Capsular Bag Protection
A dynamic elongate element expands to position a cutting loop around the lens, reducing capsular bag damage during cataract surgery.
