【摘要】： 目的：评价光学相干生物测量仪预测LASIK术后人工晶状体度数准确性。方法：应用光学相干生物测量仪测量准分子激光原位角膜磨镶术(LASIK)29例(58只眼)近视眼患者的术前和术后资料,分为低、中、高三组,随访3个月,建立屈光参数数据,比较LASIK手术后Haigis-L公式和SRK／T公式结合临床病史法(简称SRK／T公式)计算人工晶状体度数的准确性和可靠性。结果：①三组患者LASIK手术前、后等值人工晶状体屈光度数比较,Haigis L公式术后大于术前,SRK／T公式术后小于术前,差异均有显著意义(P0.01)。②分别应用Haigis-L和SRK／T公式计算三组患者LASIK手术前、后等值人工晶状体屈光度数差值(EILD),前者小于后者,差异有统计学意义(P0.05)。EILD"f1.0 D的比例分别(100%,72.2%)(70%,25%)(70%,20%),差别具有统计学意义(P0.05)。③Haigis-L组EILD与眼轴长度之间无相关性。回归方程Y=25.068+0.785x。然而SRK／T组EILD与眼轴呈中度相关性。回归方程Y=24.498+0.874x。Haigis-L组EILD与手术实际矫正量之间呈低度相关性。回归方程Y=3.033+2.418x。SRK／T组EILD与手术实际矫正量之间呈高度相关性。回归方程为Y=1.460+2.957x。结论： 1.应用光学相干生物测量仪测量LASIK患者术前屈光参数,建立数据库,将有助于今后此类病人白内障手术人工晶体计算。 2.光学相干生物测量仪附带的Haigis-L公式计算LASIK手术后人工晶体度数准确性高。
[Abstract]:Objective: to evaluate the accuracy of optical coherence biometer in predicting intraocular lens degree after LASIK. Methods: the preoperative and postoperative data of 29 cases (58 eyes) with LASIKE underwent laser in situ keratomileusis were measured with optical coherence biometer. The patients were divided into three groups: low, middle and high, followed up for 3 months to establish refractive parameter data. To compare the accuracy and reliability of Haigis-L formula and SRK/T formula combined with clinical history method (SRK/T formula) in calculating IOL degree after LASIK operation. Results the diopter of the intraocular lens before and after LASIK operation in the three groups was higher than that in the preoperative group, and the difference was significant between the three groups. The difference was significant in using Haigis-L and SRK/T formula to calculate the LASIK before LASIK operation in the three groups, respectively. The diopter difference of posterior intraocular lens was smaller than that of the latter, and the difference was statistically significant (P 0.05). The proportion of EILD "f 1.0 D was 100% and 72.2%, respectively. There was no correlation between EILD and axial length in group P0.05. 3 Haigis-L. The regression equation is YC 25.068 0.785x. However, there was a moderate correlation between EILD and eye axis in SRK/T group. The regression equation Y _ (24.498) 0.874x.Haigis-L group showed a low correlation between EILD and the actual corrected amount. There was a high correlation between EILD and the actual corrected amount of operation in the regression equation YC 3.033 2.418x.SRK/T group. The regression equation is YC 1.460 2.957x. Conclusion: 1. Using optical coherence biometer to measure the preoperative refractive parameters of LASIK patients and to establish a database will be helpful to the calculation of IOL in cataract surgery in the future. 2. The accuracy of calculating the degree of intraocular lens after LASIK operation by the Haigis-L formula attached to the optical coherent biometer is high.
