摘　　要：目的:探讨视网膜脱离巩膜环扎加压术后眼部屈光状态的改变。方法:用眼科A超、检影验光等对23例23眼原发性视网膜脱离患者手术前1d及术后1,4,12wk时的眼轴长度、眼屈光度等进行测量并将结果进行比较。结果:眼轴长度、晶状体厚度增加在术后1,4,12wk时均较术前增长(P<0.01)。眼屈光度增加、前房深度变浅,及角膜曲率增加在术后1,4,12wk时均较术前增加,且向负值偏移(P<0.05)。结论:巩膜环扎加压术后眼轴长度和屈光状态的变化与眼内嵴有关,术后眼轴增长是眼屈光度负值增加的主要因素。AIM：To investigate changes in refractive state after scleral encircling and buckling surgery·METHODS：Twenty-three cases（23 eyes） that were successfully treated for rhegmatogenous retinal detachment with scleral encircling and buckling were measured with A-scan ultrasonography and given rtinoscopy optometry 1 day before surgery,as well as 1 week,4 weeks and 12 weeks after surgery.Refractive factors,axial length,chamber depth,lens thickness,refractive power of cornea and diopter status of the eyes were measured and compared pre-and post-operatively·RESULTS：When compared to the data obtained before surgery,significant increases in both axial length and lens thickness of the eyes were observed on the 1st,4th and 12th week after surgery（P〈0.01 for both factors,but P〈0.05 for diopter strength and anterior chamber shallowing refractive power increase.Diopter strength had a tendency to shift to a negative value·CONCLUSION：Axial length and diopter strength increased after surgery.This suggests that the myopic shift after scleral encircling and buckling surgery may be primarily caused by the increase of axial length.
