PAI-LASIK is about the same as LASIK, with one important exception: instead of removing corneal tissue, the surgeon would place an inlay in your eye and ablate that.

Peyman, MD, invented the concept of a photoablative inlay. Because no corneal tissue is ablated during excimer laser treatment, all of the 3 problems mentioned above are solved. The plastic inlay is sculpted by the excimer laser and, then, left in between the flap and the underlying stroma. Bausch & Lomb acquired marketing and development rights to this PAI-LASIK photoablative inlay concept; however, animal studies have not begun yet.<p></p></P><P align=left><p> </p></P><P align=left><IMG src="http://www.eyecaresource.com/images/eye-care-logo.jpg" border=0>http://www.eyecaresource.com/eye-surgeries/lasik-eye-surgery.php</P><P align=left><B>Photoablative Inlay (PAI) LASIK<p></p></B></P><P align=left><B>PAI-LASIK</B> is new research being done to <U>LASIK Surgery</U>.
