Dear Colleagues, Dear O&O Customers,

Recently the lathing of hydrophobic material has become of great interest to the industry and is a critical process for future of many IOL manufacturers.

At O&O mdc we have been working on a process to machine hydrophobic at “room temperature” that can be fully automated.

This process has been developed over time in conjunction with partners and O&O mdc is pleased to announce that it is now able to share this know-how with the industry. But unlike others, we would like to support manufacturers by offering this know- how free of charge as it is critical to the growth of the lathed hydrophobic market segment.

It is important to understand that lathing at room temperature is possible with some hydrophobic material, by optimizing the cutting parameters but also some small machine software additions and specific diamond tool designs with “OnOTin” spray mist technology.

Softer materials may require slight additional cooling, that can be achieved for example with AMCC cooling units designed to cool the material surface only, with no adverse affect to the lathe; especially if the spindle is temperature controlled via a heat exchange unit.

By using a cooling device, the quality of the lens will only be improved and virtually “polish free” IOLs can be achieved...!

However a good understanding of “room temperature” machining will allow you to lathe and mill hydrophobic lenses much more efficiently.

O&O mdc remains at your disposal to provide training on this process; free of charge. So please contact us for any further information.

With Thanks & Regards
