摘　　要：目的　探讨准分子激光原位角膜磨镶术 (L ASIK)后眼压测量值的变化。方法　采用非接触式眼压计对 34 0只眼 (176例患者 )行 L ASIK手术后行眼压测量。结果　L ASIK后眼压测量值明显低于术前 (t=5 6 .118,P<0 .0 0 1)。按术前屈光度将患眼分成 4组。 组 :- 3.0 0～ - 6 .0 0 D; 组 :- 6 .0 0～ - 9.0 0 D; 组 :- 9.0 0～ - 12 .0 0 D; 组 :- 12 .0 0 D以上 ,每组术后眼压测量值均明显低于术前 (t>15 ,P<0 .0 0 1)。切削等值球镜度与术后眼压测量差值明显相关 (r=0 .16 4,P=0 .0 0 2 ) ,在控制切削等值柱镜度的影响后对二者进行偏相关分析 ,偏相关系数 r=0 .15 2 ,P=0 .0 0 5。结论　准分子激光原位角膜磨镶术后眼压测量值明显低于术前 ,并且眼压测量差值随切削等值球镜度的增加而增大。Objective To evaluate the variance of intraocular pressure readings after laser in suit keratomileusis (LASIK). Methods The intraocular pressure readings of 340 eyes were measured with noncontact tonometer(NCT) before and one year after LASIK.Results The IOP readings after LASIK were lower than those before LASIK ( t =56 118, P< 0.001). The data were divided into four groups according to the diopter before LASIK: groupⅠ: -3.00^-6.00D; groupⅡ: -6.00^-9.00D; group Ⅲ:-9.00^-12.00D; group Ⅳ: more than -12.00D. The IOP readings after operation were lower than those before operation in each group ( t >15, P < 0.001). The spherical equivalent was significantly correlated with the reduction in IOP readings ( r=0.164, P =0.002) and the partial correlative coefficient was 0.152( P =0.005) if the cylindrical equivalent was controled.Conclusion IOP readings after LASIK are lower than those before operations. The differences of IOP readings between before and after LASIK are increased with the increasment of the degree of laser treatment.
