Refocus Group, Inc. announced that it has successfully completed its 12-month follow-up on 360 patients in its pivotal trial of the VisAbility Micro-Insert System for presbyopia. The announcement paves the way for preparation of Refocus Group's Pre-Market Approval submission to the U.S. Food and Drug Administration (FDA). Study investigators will present their initial findings at sessions during the ASCRS ASOA Symposium & Congress held by the American Society of Cataract and Refractive Surgery and the American Society of Ophthalmic Administrators at the Los Angeles Convention Center, 1201 S. Figueroa St., Los Angeles, Calif., May 5-9, 2017. The current clinical trial, "A Prospective, Multicenter Clinical Trial of The VisAbility™ Implant System for Improvement of Near Visual Acuity in Presbyopic Patients," enrolled a total of 360 subjects between 45 and 60 years of age, at 13 clinical sites in the U.S. Given the substantial previous clinical trial history and data on the device, the FDA granted Refocus Group a 12-month follow-up for submission, versus the usual 24 months.
