Overview STAAR Surgical Company designs, develops, manufactures, and sells implantable lenses for the eye and accessory delivery systems used to deliver the lenses into the eye. We are the leading manufacturer of lenses used worldwide in corrective or “refractive” surgery. We have been dedicated solely to ophthalmic surgery for over 40 years.
We are the world’s leading manufacturer of intraocular lenses for patients seeking lens-based refractive vision correction, and we also make lenses for use in surgery to treat cataracts. All the lenses we make are foldable, which allows the surgeon to insert them into the eye through a small incision during minimally invasive surgery.
All of our ICLs are foldable, which allows the surgeon to insert them into the eye through a small incision during minimally invasive surgery. Further, while ICLs are intended to be permanent, our ICLs are reversible lens implants, meaning they can be removed by a doctor if desired.
