目的探讨伴发后巩膜葡萄肿的高度近视性白内障人工晶状体(IOL)度数测算的准确性。方法将2021年8—12月新疆维吾尔自治区人民医院高度近视性(眼轴≥26.5 mm)白内障患者75例(75眼)根据眼部B超是否伴有后巩膜葡萄肿分为2组。术前使用IOL Master 700系统自备的6种公式(Holladay 2、SRK/T、Hoffer Q、Holladay 1、Haigis及Barrett UniversalⅡ)测算IOL度数。利用眼B超测量后巩膜葡萄肿宽度及深度。术中植入IOL类型:HOYA 251(22眼)、Zeiss 601(24眼)和爱博诺德ALD(29眼)。随访3个月,记录屈光度平均误差(MNE)和平均绝对误差(MAE)。结果所有手术均顺利完成,无特殊并发症。6种公式测算的MNE和MAE差异有统计学意义(F=6.058,P=0.001;F=3.768,P=0.003);其中SRK/T和Barrett UniversalⅡ测算的MNE最小(依次为0.45 D和0.37 D),Barrett UniversalⅡ测算的MAE最小,为0.54 D。在高度近视患者中,眼轴越长,屈光度误差越大,眼轴长度与Holladay 2、SRK/T、Hoffer Q及Holladay 1这4种公式测算的MNE呈正相关(r=0.482,0.459,0.529,0.530;P=0.002,0.004,0.001,0.001);与MAE亦呈正相关(r=0.490,0.443,0.533,0.533;P=0.002,0.005,0.001,0.001)。3款IOL利用6种公式测算的MNE和MAE差异无统计学意义(P均>0.05)。所有患者中伴发后巩膜葡萄肿者56眼(74.7%),有后巩膜葡萄肿者的MNE和MAE均比无葡萄肿者高。其中Holladay 2、SRK/T、Hoffer Q及Holladay 1这4种公式计算的MNE和MAE,在有、无葡萄肿者之间差异有统计学意义(P均<0.05)。利用Barrett UniversalⅡ公式计算的MAE分布结果显示,在有后巩膜葡萄肿的56眼中,32眼(57.1%)MAE<0.5 D,11眼(19.6%)MAE为0.5~1.0 D,13眼(23.3%)MAE≥1.0 D;在无后巩膜葡萄肿的19眼中,11眼(57.9%)MAE<0.5 D,8眼(42.1%)MAE为0.5~1.0 D,没有患者MAE≥1.0 D;两亚组患者MAE分布确切概率法显示,有后巩膜葡萄肿者MAE变异度更大(P=0.027)。结论伴发后巩膜葡萄肿的高度近视性白内障患者在IOL测算时变异度更大,并且容易出现远�
Objective To investigate the accuracy of intraocular lens(IOL)power measurement in high myopia cataract with posterior scleral staphyloma.Methods The data of 75 eyes of 75 patients with high myopic(axial length≥26.5 mm)cataract from August to December 2021 in People’s Hospital of Xinjiang Autonomous Region were studied.All cases were divided into two groups based on whether there was posterior scleral staphyloma in ocular B-ultrasound examination.Before the operation,six formulas(Holladay 2,SRK/T,Hoffer Q,Holladay1,Haigis and Barrett universal II)prepared by the IOL master 700 system were used to calculate the IOL degree.The width and depth of posterior scleral staphyloma were measured by B-ultrasound.Implanted IOL included Hoya 251(22 eyes),Zeiss 601(24 eyes)and ALD(29 eyes).The mean numerical error(MNE)and mean absolute error(MAE)of refractive error after intraocular lens implantation were recorded during the follow-up period of 3 months.Results All the operations were successfully completed without special complications.The difference of MNE and MAE among six formulas in high myopia were statistically significant(F=6.058,P=0.001;F=3.768,P=0.003).Among them,the MNE calculated by SRK/T and Barrett Universal II formula were relatively small(0.45 D and 0.37 D respectively),and the MAE calculated by Barrett Universal II formula is the smallest with 0.54 D.In the high myopia patients,the refractive error increased as the length of the eye axis increased.The axial length was positively correlated with MNE measured by Holladay 2,SRK/T,Hoffer Q,Holladay1 formulas(r=0.482,0.459,0.529,0.530,P=0.002,0.004,0.001,0.001).It was also positively correlated with MAE(r=0.490,0.443,0.533,0.533,P=0.002,0.005,0.001,0.001).The MNE and MAE calculated by the six formulas between the three IOLs had no statistical difference(P>0.05).In the high myopia group,74.7%of the patients had posterior scleral staphyloma.MNE and MAE were higher in those with posterior scleral staphyloma than those without staphyloma.Among them,MNE and MAE calc
