IOL LENS

IOLs are artificial lenses implanted during eye surgery to correct vision problems. Diamond tools are crucial in IOL manufacturing due to their precision and ability to create flawless surfaces, ensuring optimal visual outcomes for patients. For years, EHWA’s cutting technology team has developed the cutting tools for IOL machining to meet various requirements.

EHWA’s SCD tools for IOL machining provide:

  • Turning solution for machining aspheric surface

  • Endmilling solution for machining step-shape surface (Highly precise machining by meticulous location of diamond

Ehwa's SCD tools can provide various solutions for IOL (Intraocular Lens) processing. We offer precision turning solutions for processing non-spherical shapes and milling solutions for machining step shapes. Particularly, when it comes to endmill types, precision in rotation is crucial, making dimensional accuracy optimization essential.
