KAMRA镶嵌术已获得CE认证，可在欧盟应用，在美国已获得研究性器械豁免(IDE)，属于研究中的器械。

AcuFocus is a privately-held medical device company that developed the KAMRA(TM) inlay, the proven treatment of presbyopia. The Company is based in Irvine, California.

The KAMRA Inlay

As an intra-corneal inlay, KAMRA Vision(TM) is designed to create a small aperture effect, allowing the eye to see near and intermediate objects more clearly while maintaining distance vision. To date, more than 5,000 KAMRA inlays have been implanted worldwide. The inlay is available in select markets across Europe, Asia-Pacific, Middle East and South America.

The KAMRA inlay has received CE mark for use in the European Union and is an investigational device under Investigational Device Exemption (IDE) in the United States.
