Laser Surgery TRIZ Cases
- One-piece femtosecond laser patient interface for single-stage docking
Integrating suction components eliminates multi-step docking errors while applanation plate coatings ensure precise corneal measurement.
- Ophthalmic Laser Measurement for Capsular Bag Distance
Optical measurement replaces preoperative estimates to resolve effective lens position precision limits.
- Dual-Beam Laser Lenticule Cutting
Simultaneous dual-surface processing eliminates vertical optics movement, resolving the contradiction between cutting precision and speed.
- Illuminated Laser Probe with Adjustable Fiber Tip
A manually adjustable mechanism extends or retracts the distal laser fiber tip to resolve the contradiction between surgical precision and device complexity.
- Corneal Laser Ablation Using Topographic Astigmatism Data
A laser ablation pattern derived from corneal topography and epithelial thickness data corrects anterior surface irregularities.
- Achromatic Optical System for Laser Light Source Aberration Correction
An achromatic optical system corrects chromatic aberration in laser-operated light sources, ensuring homogeneous light distribution and high yield.
- Self-Supporting Light Guide for Glaucoma Applicator Head
A self-supporting light guide extends within a cavity to deliver laser treatment.
- Ophthalmic Surgery Planning Device for Corneal Refractive Correction
A planning device generates laser control data to form corneal incision surfaces for refractive correction.
- Beam Deflection Device for Laser Pattern Generation
A beam deflection device spatially offsets a laser beam using a dispersive element to generate rotation patterns.
- Ophthalmic Illumination System Achromatic Collimator
Dichroic mirrors reflect light beams to achieve uniform beam diameter and coupling efficiency for multi-wavelength ophthalmic illumination.
