title: Comparison of intraocular pressures at different points in human's cornea before and after laser in situ keratomileusis with tono-pen tonometer.
abstract: In order to explore the difference of intraocular pressure (IOP) at different points of cornea before and after laser in situ keratomileusis (LASIK), IOP was measured by Tono-Pen Tonometer at central cornea, pericentral cornea and limbus respectively and analyzed statistically. After LASIK, IOP was dropped significantly at central cornea and pericentral cornea (P<0.05), while no statistically significant change occurred at limbus (P>0.05). There was no statistically significant difference in IOP at different points before LASIK (F=0.110, P=0.896), but statistically significant difference was found after LASIK (F=7.375, P=0.001). It was suggested that reliable IOP after LASIK could be obtained from the limbus by Tono-Pen tonometer.
