<P>LASEK基本介绍</P><P>LASEK – Laser-Assisted in Situ Epithelial Keratomileusis
LASEK, or Laser-Assisted in Situ Epithelial Keratomileusis, is a variation of LASIK surgery that involves the creation of a thin epithelial flap with an alcohol </P><P>solution, rather than the thicker corneal flap created with a microkeratome (a special scalpel) during LASIK. This avoids some flap-related complications. After the </P><P>creation of the flap, the laser eye surgeon ablates the underlying corneal tissue much like LASIK and PRK. The flap is then replaced and smoothed over. This procedure </P><P>is recommended for patients with thin corneas because it saves about 160 microns more corneal tissue than LASIK. It is important to note that this procedure is an </P><P>“off-label” use of the excimer laser. This means that although the FDA has not yet approved this use of the laser, many ophthalmologists consider LASEK the best </P><P>option for some patients.</P>
