目的:评估术中波前像差测量(IWA)与现代人工晶状体公式在近视后激光视力矫正(LVC)患者行囊张力环放置白内障手术中的准确性。
方法:这是一个在学术门诊中心进行的回顾性图表综述。纳入2017年5月至2019年12月1日由一名外科医生进行IWA白内障手术的所有近视后LVC眼。所有患者均接受囊膜张力环(CTR)。平均数值误差(MNE),中值数值误差(MedNE),以及0.50D内的预测误差百分比,0.75D,并对上述公式计算1.00D。
结果:纳入18例患者的27只近视后LVC眼。在近视后LVC中,带Optiwave折射率分析(ORA)的MNE,巴雷特真K(BTK),海吉斯,Haigis-L,Shammas,SRK/T,Hill-RBFv3.0和W-KAL调整后的Holladay1分别为+0.224、-0.094、+0.193、-0.231、-0.372、+1.013、+0.860和+0.630(F=8.49,p<0.001)。MedNE分别为+0.125、-0.145、+0.175、+0.333、+0.333、+1.100、+0.880和+0.765(F=7.89,p<0.001),分别。与成对分析中的ORA相比,BTK在MNE(p<0.001)和MedNE(p=0.033)中提供了更高的准确性。如果ORA与常规选择BTK建议的IOL功率,30%和15%的眼睛会预测远视结果,分别(p=0.09)。
结论:我们的研究表明,在接受CTRs白内障手术的近视后LVC眼中,BTK在准确性方面比ORA更准确,并且远视结果的眼睛百分比较低。海吉斯,Haigis-L,在准确性和远视结果的眼睛百分比方面,Shammas的结果与ORA相似。平均而言,Shammas和Haigis-L建议与BTK相比,IOL的结果比预期的更近视。
OBJECTIVE: To assess the accuracy of intraoperative wavefront aberrometry (IWA) versus modern intraocular lens formulas in post-myopic laser vision correction (LVC) patients undergoing cataract surgery with capsular tension ring placement.
METHODS: This is a retrospective chart review conducted at an academic outpatient center. All post-myopic LVC eyes undergoing cataract surgery with IWA from a single surgeon from 05/2017 to 12/2019 were included. All patients received a capsular tension ring (CTR). Mean numerical error (MNE), median numerical error (MedNE), and percentages of prediction error within 0.50D, 0.75D, and 1.00D were calculated for the above formulas.
RESULTS: Twenty-seven post-myopic LVC eyes from 18 patients were included. In post-myopic LVC, MNE with Optiwave Refractive Analysis (ORA), Barrett True K (BTK), Haigis, Haigis-L, Shammas, SRK/T, Hill-RBF v3.0, and W-K AL-adjusted Holladay 1 were + 0.224, - 0.094, + 0.193, - 0.231, - 0.372, + 1.013, + 0.860, and + 0.630 (F = 8.49, p < 0.001). MedNE were + 0.125, - 0.145, + 0.175, + 0.333, + 0.333, + 1.100, + 0.880, and + 0.765 (F = 7.89, p < 0.001), respectively. BTK provided improved accuracy in both MNE (p < 0.001) and MedNE (p = .033) when compared to ORA in pairwise analysis. If the ORA vs. BTK-suggested IOL power were routinely selected, 30% and 15% of eyes would have projected hyperopic outcomes, respectively (p = 0.09).
CONCLUSIONS: Our study suggests that in post-myopic LVC eyes undergoing cataract surgery with CTRs, BTK performed more accurately than ORA with regard to accuracy and yielded a lower percentage of eyes with hyperopic outcomes. Haigis, Haigis-L, and Shammas yielded similar results to ORA with regard to accuracy and percentage of eyes with hyperopic outcomes. On average, Shammas and Haigis-L suggested IOLs that would yield outcomes more myopic than expected when compared to BTK.
