    New corneal inlay offers choice for presbyopia improvement


    Several corneal inlays have been approved worldwide for presbyopia, but there are currently only two devices in the U.S. market: the Raindrop Near Vision Inlay and the Kamra Inlay (AcuFocus). The former improves near vision by changing the physical shape of the cornea while the latter uses the pinhole effect to improve depth-of-focus.

    Still, the two inlays are more complementary than competitive, Dr. Chu said. Experience outside the United States suggests the Kamra Inlay may be more suitable for patients whose refraction is around -0.75 D. The Raindrop Inlay may be more appropriate for patients whose refraction is between 0.00 and +0.25 D.

    “Patients and surgeons might prefer one device [over] the other depending on their individual vision and situation,” Dr. Chu said. “The key message is that we now have another tool to treat presbyopia that uses existing femtolaser technology and familiar surgical techniques.”
