摘　　要：目的　探讨LASIK手术对近视患者调节和隐斜的影响。方法　对LASIK手术的近视患者 60人在术前和术后一个月进行调节力和看近隐斜度的测定 ,并进行对比分析。结果　术前调节力平均值为 6 77D± 1 41D ,术后调节力平均值为 7 3 9D± 1 2 5D。统计学分析二者之间的差异有非常显著性意义 (t =6 887,P <0 0 1)。术前裸眼隐斜度的平均值为 -10 18± 5 0 7Δ。术前戴矫正镜片隐斜度的平均值为 -1 99± 6 49Δ ;术后裸眼隐斜度的平均值为 -4 92± 4 46Δ。统计学分析 ,术前裸眼与戴矫正镜片隐斜度平均值之间的差异有非常显著性意义 (t =11 898,P <0 0 1) ;术前裸眼与术后裸眼隐斜度平均值之间的差异有非常显著性意义 (t =11 10 1,P <0 0 1) ;术后裸眼与术前戴矫正镜片隐斜度平均值之间的差异有非常显著性意义 (t =3 0 45 ,P <0 0 1)。结论　LASIK手术后近视患者的调节力有一定增加。矫正眼镜和LASIK手术可以减少近视患者看近外隐斜。较长期的影响尚有待于观察。Objective To study the effect of LASIK on accommodation and heterophoria in myopes.Methods The accommodation amplitude and heterophoria on near (33 cm) fixation were measured before and after LASIK in 60 patiens with myopia.Results The mean value of accommodation amplitude were 6.77D±1.25D postoperatively.Statistically the differences was significant (t=6.887,P<0.01).The mean value of heterophoria without correction is -10.18±2.07△,that with correction was -1.99±6.49△ preoperatively and -1.92±4.46△ postoperatively.Statistically the differences of the means of heterophria between with and without correction preoperatively was significant (t=11.898,P<0.01),the diferences between preoperatively and postoperatively wirhout correction was significant (t=11.101,P<0.01),and that between with correction preoperatively and without correction postoperatively was significant (t=3.045,P<0.01).Conclusions After LASIK the amount of exophoria on near fixation declines and the accommodation amplitude increases.
