Laser Surgery TRIZ Cases

A processing module generates control data for femtosecond laser systems to limit treatment time and irradiation intensity.

A femtosecond laser pulse train uses a nanosecond-interval prepulse to initiate an avalanche process, reducing lateral damage during corneal tissue processing.

Beveled sleeve and notched design minimize radial tears by ensuring predictable resistive heating loop expansion.

Networked central computer diagnoses surgical machine faults remotely, minimizing downtime caused by inefficient on-site technician visits.

A laser treatment device detects pressure transients to control radiation parameters in real time.

Dynamic focal point adjustment via scattered light intensity feedback minimizes capsulotomy overcut while reducing energy exposure and procedure time.

Merging the lens and cone into a single unit eliminates assembly steps that compromise sterility and positioning precision.

A concave acoustic diverter disperses photodisruption shock waves to prevent refocusing, protecting retinal integrity from tissue damage.

Femtosecond laser ionizes corneal water to generate reactive oxygen species, increasing rigidity without cytotoxicity.

A reconfigurable layer and immiscible liquids adjust the meniscus curvature to correct refractive surprises after intraocular lens implantation.

External energy delivery tensions zonules to open the iridocorneal angle, reducing intraocular pressure without invasive surgery.
