Centricity Vision Inc. received U.S. FDA clearance for technology designed to integrate with modern phacoemulsification or “phaco” systems that use ultrasound energy to emulsify the eye's native internal lens during cataract surgery. Centricity’s new Zeptolink interocular lens (IOL) positioning system is used in conjunction with phaco systems to surgically remove the natural lens of the eye as the first step in cataract surgery.
