Product Features:
1. Patented pentafocal Fourier Harmonic diffractive technology
12 Fourier harmonic components, fine-tuning the energy to 5 designated focal points, the diffraction rings are smooth, and the waveform is continuously derivable, achieving nearly 100% lightenergy efficiency with minimal optical interference such as halos, glare, and starbursts.
2. P.U.R.E. technology
Purification and extraction using organic solvents ensurethe "zero" of material impuri-ties and the lasting clarity ofintraocular lenses, enhancing biocompatibility.
3. Nanoscale CNC machining technology
No polishing is required, ensuring that the processed surface profile accurately meets the design requirements, reducing the risk of optical interference and energy loss even further.
