The Food and Drug Administration has approved Irvine-based AcuFocus Inc.’s Kamra corneal inlay for treating presbyopia.

Presbyopia is the age-related loss of near vision and affects almost everyone over the age of 50; it is estimated that more than 114 million people have the condition.

Kamra is implanted in a patient’s eye and is intended to replace reading glasses for people with presbyopia.

“After a decade of research, development and clinical investigation, we are delighted to bring this [technology] to surgeons and patients in the U.S.,” said AcuFocus Chief Executive James Mazzo in a statement.

AcuFocus is venture-backed. Its investors include Versant Ventures, which has an office in Newport Beach.
