换一批Comparison of Intraocular Pressures at Different Points in Human's Cornea before and after Laser in situ Keratomileusis with Tono-Pen Tonometer
摘要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.
