Abstract

BACKGROUND

To compare refractive index variation between Hoffer-Q, Haigis and SRK/T formulas used for preoperative biometry calculation in patients with axial length >25 mm, undergoing cataract surgery.

MATERIALS AND METHODS

This is a randomized clinical trial study was performed on 54 eyes of 54 patients with ages of 40-70 years old and axial length >25 mm classified into three groups that their IOL POWER were calculated by Haigis, SRK/T and Hoffer-Q formulas before undergoing cataract surgery. Their refractive index variations were calculated from the difference between predicted refractive error formula and actual post-operative refractive error formula. The collected data was entered in SPSS software and was analyzed by ANOVA and Chi-square statistical test.

RESULTS

With comparison sphere, astigmatism and spherical equivalent indexes before and after of cataract surgery between Haigis, SRK/T, and Hoffer-Q formulas, statistically significant differences were found between the mean of sphere and SE indexes in patients with use of Haigis and SRK/T formulas that have been more favorable post-operative refraction.

CONCLUSIONS

Haigis formula and then, with slight difference, SRK/T formula have better and more acceptable post-operative refraction results than Hoffer-Q formula in patients with high axial myopia. Therefore, it is recommended using Haigis and SRK/T formulas for IOL power calculation in patients with high axial myopia undergoing cataract surgery.

摘要

背景

比较用于眼轴长度>25mm的白内障手术患者术前生物测量计算的Hoffer-Q、Haigis和SRK/T公式之间的折射率变化。

材料与方法

这是一项随机临床试验研究，对54例年龄在40 - 70岁、眼轴长度>25mm的患者的54只眼睛进行研究，将其分为三组，在白内障手术前分别通过Haigis、SRK/T和Hoffer-Q公式计算人工晶状体度数。根据预测屈光不正公式与实际术后屈光不正公式之间的差异计算其折射率变化。收集的数据录入SPSS软件，采用方差分析和卡方统计检验进行分析。

结果

比较Haigis、SRK/T和Hoffer-Q公式在白内障手术前后的球镜、散光和等效球镜指标，发现使用Haigis和SRK/T公式的患者球镜和等效球镜指标均值之间存在统计学显著差异，术后屈光更理想。

结论

在高度轴性近视患者中，Haigis公式以及与Haigis公式有细微差异的SRK/T公式比Hoffer-Q公式具有更好且更可接受的术后屈光结果。因此，建议在进行白内障手术的高度轴性近视患者中使用Haigis和SRK/T公式计算人工晶状体度数。
