Irvine eye device maker AcuFocus Inc. said today it closed a $65 million investment.

AcuFocus makes the Kamra, which is implanted in a patient’s cornea and is designed to correct presbyopia, a condition that occurs in nearly all adults. The condition often requires dependence on reading glasses.

The company said it would use the money to expand commercially in new and existing markets.

Cowen Royalty Healthcare Partners of Stamford, Conn., led AcuFocus’ new investment.

Other investors included Medtronic Inc., a Minnesota device maker with operations in Irvine and Santa Ana; Rochester, N.Y.-based Bausch & Lomb Inc., which has an eye surgery hub in Aliso Viejo; and Versant Venture Management LLC, which has a Newport Beach office.

AcuFocus was founded 10 years ago in suburban Atlanta and moved to Orange County in 2004.
