Corneal Inlays for Presbyopia Explanted Due to Corneal Haze

The KAMRA inlay (AcuFocus, Inc., Irvine, CA) was the first corneal inlay to receive approval from both the European Commission and the U.S. Food and Drug Administration. It uses the principle of small-aperture optics to improve near vision by increasing the depth of focus.1 The current version (ACI 7000 PDT) is a 5- μm thick, opaque, ring-shaped implant measuring 3.8 mm in diameter with a central 1.6-mm aperture that allows only central collinear light to reach the retina.1 The central aperture has 8,400 laser-etch perforations with a random pattern of holes, each 5 to 11 μm in diameter
