摘　　要：目的 比较Nd∶YAG激光后囊切开术中使用接触镜及未使用接触镜两组患者的累积能量、激光点数、平均能量及操作过程耗费时间。方法 前瞻性选择2019年11月~2021年5月于暨南大学附属深圳爱尔眼科医院门诊确诊的后发性白内障患者80例(80眼)。按照随机数字表法进行分组,单号患者激光过程中不使用接触镜作为观察组,共40例(40眼);双号患者使用接触镜作为对照组,共40例(40眼)。记录激光过程中使用的能量范围、累积能量、激光点数、激光操作过程耗时(分钟)。应用SPSS22.0统计学软件对两组患者数据进行方差齐性检验,符合方差齐性的资料采用配对样本t检验,不符合方差齐性的资料采用非参数秩和检验。结果 两组患者术后视力均明显提高,差异有统计学意义(P<0.001)。所有观察患者激光后0.5 h及术后7 d均未出现眼压明显升高,两组患者激光后0.5 h眼压、7 d眼压、激光后视力比较差异均无统计学意义(P=0.089,P=0.145,P=0.431)。观察组激光术中使用的累积能量与对照组比较差异无统计学意义(P=0.456),观察组激光术中使用的平均能量高于于对照组,两组比较差异有统计学意义(P<0.001)。观察组患者激光术中点数少于对照组,两组比较差异有统计学意义(P<0.001)。观察组操作过程耗时少于对照组,两组比较差异有统计学意义(P<0.001)。结论 Nd∶YAG激光后囊切开术中未使用接触镜与使用接触镜相比,累积能量无明显差异,平均能量使用较大,但可减少激光点数、操作时间较短,两组患者临床效果观察差异无统计学意义。Objective Comparison of Nd:YAG laser posterior capsulotomy using contact lens and not using contact lens in the two groups of patients with accumulated energy,laser points,average energy and operation process time-consuming.Methods A prospective collection of 80 eyes of patients with after-cataract diagnosed in the outpatient clinic of our hospital from November 2019 to May 2021.Number 1-80 according to the random number method,lottery method,single-number do not use contact lenses during the laser process,as the experimental group,40 people(40 eyes);double-number use contact lenses,as the control group,40 People(40 eyes).Record the range of energy used in the laser process,the accumulated energy,the number of laser points,and the time of the laser operation process.Results Postoperative visual acuity of the two groups was significantly improved,and the difference was not statistically significant(P<0.001).There was no significant increase in intraocular pressure in all observed patients half an hour after the laser and 7 days after the operation,and there was no significant difference of intraocular pressure half an hour after the laser,the intraocular pressure 7 th day,and the visual acuity after the laser between two groups(P>0.05).There was no significant difference in the cumulative energy between the experimental group and the control group(P=0.456).The number of laser intraoperative points in the experimental group was less than that in the control group,and the difference between the two groups was statistically significant(P<0.001).The operation time of the experimental group was less than that of the control group,and the difference between the two groups was statistically significant(P<0.001).Conclusions Nd∶YAG laser posterior capsulotomy,no contact lens was used compared with the use of contact lens,there was no significant difference in accumulated energy,and the average energy used was larger,but the number of laser points could be reduced,and the operation time was shorter.The clinical effect of
