PEARL inlay uses allogenic tissue for presbyopic correction

PEARL is an acronym for PrEsbyopic Allogenic Refractive Lenticule. This technique was described by Soosan Jacob as a treatment for presbyopia. The PEARL inlay utilizes the principle of a shape-changing inlay in order to improve near vision.Corneal inlays can be classified as pinhole aperture inlays (Kamra, AcuFocus), shape-changing inlays (Raindrop, ReVision Optics; PEARL inlay) and refractive optic inlays (Flexivue Microlens, Presbia; Icolens, Neoptics). They can also be classified as synthetic inlays, including most inlays currently available on the market, and allogenic inlays, such as the PEARL inlay.
