Abstract

We demonstrate the implementation of a zonal diffractive intraocular lens design based on VSY Biotechnology's recent patent [1], using a custom-developed femtosecond fiber laser system optimized for transparent material processing. Our system operates at 1030 nm with sub-500 fs pulses, employing two distinct scanning strategies: a high-precision 4-axis translation stage synchronized with spiral scanning for precise Fresnel zone patterning (1.1 μm depth modulation), and a galvo scanner with f-theta lens configuration for rapid haptic cutting achieving industrial-compatible processing speeds (<40 s/lens).
