摘　　要：目的:评估一种智能手机辅助的新型“任意点两步法”在白内障超声乳化吸出联合人工晶状体植入术中寻找目标轴位的便利性和准确性。方法:前瞻性观察性研究。选取2021-10/2022-04于我院拟行白内障超声乳化吸出联合人工晶状体植入术的年龄相关性白内障患者62例62眼。随机分为两组,对照组31例31眼采用裂隙灯下标记的“传统两步法”标记人工晶状体的目标轴位,试验组31例31眼采用智能手机辅助的“任意点两步法”标记人工晶状体的目标轴位。术中均采用Callisto eye导航系统作为标准参照,计算参照标记点的偏差值(偏差-1)、目标轴位标记点的偏差值(偏差-总)和参照标记点到目标轴位标记点夹角的偏差值(偏差-2),并记录术前轴位标记用时。结果:试验组偏差-1值和偏差-总值均低于对照组(1.06°±1.39°vs 2.48°±2.23°,1.77°±1.54°vs 2.81°±1.58°,均P<0.01),但两组偏差-2值无明显差异(1.35°±1.40°vs 1.48°±1.79°,P>0.05)。试验组术前轴位标记用时短于对照组(1.77±1.70 min vs 2.88±3.20 min,P<0.01)。结论:与“传统两步法”相比,智能手机辅助的“任意点两步法”在白内障超声乳化吸出联合人工晶状体植入术中寻找目标轴位的过程操作简便省时、准确性高。AIM:To evaluate the convenience and accuracy of a novel smartphone-assisted“any-point two-step method”for finding the target axial position in cataract phacoemulsification combined with intraocular lens(IOL)implantation.METHODS:Prospective observational study.A total of 62 cases(62 eyes)of patients with age-related cataracts who underwent cataract phacoemulsification combined with IOL implantation in our hospital from October 2021 to April 2022 were selected.They were randomly divided into two groups:31 cases(31 eyes)in the control group were applied with the“traditional two-step method”using slit lamp to mark the target axial position of the IOL,and 31 cases(31 eyes)in the experimental group were applied with the smartphone-assisted“two-step method”to mark the target axial position of the IOL.The Callisto eye navigation system was used as a standard reference,and the deviation of the reference marking point(deviation-1),the deviation of the target axial marking point(deviation-total),and the deviation of the angle from the reference marking point to the target axial marking point(deviation-2)were calculated and recorded as the preoperative axial marking time.RESULTS:Both deviation-1 and deviation-total values were lower in the experimental group than those in the control group(1.06°±1.39°vs 2.48°±2.23°,1.77°±1.54°vs 2.81°±1.58°,all P<0.01),but there was no significant difference in the deviation-2 values between the two groups(1.35°±1.40°vs 1.48°±1.79°,P>0.05).The preoperative axial marking took shorter time in the experimental group than in the control group(1.77±1.70 min vs 2.88±3.20 min,P<0.01).CONCLUSION:The smartphone-assisted“any-point two-step method”for finding the target axial position in cataract phacoemulsification combined with IOL implantation is simple,time-saving,and accurate compared with the“traditional two-step method”.
