Sterling AT A GLANCE

Sterling Ultra Precision is the world’s largest manufacturer of ultra-precision ophthalmic lathes for the production of contact lenses and IntraOcular Lenses (IOLs).

Our route to providing world-class lathe technology is the Sterling-Precitech partnership which began in 1991. This collaboration resulted in the introduction of the Optoform® series and Nanoform® series, the first line of CNC lathes to the contact lens and intraocular lens industries. Today, the Optoform brand is the industry standard and is used by every leading manufacturer of contact lenses and IOLs.
