Abstract

Purpose: The aim of this study was to compare the biometric measurements and different formulas for calculating intraocular lens (IOL) power by using the Lenstar LS900 biometer for optical low-coherence reflectometry before and after induction of cycloplegia in the adult population.

Materials and methods: In this cross-sectional study, 168 eyes of 168 healthy volunteers aged 40 - 86 years (59.22 ± 11.57) were included. Biometric measurements, including axial length (AL), anterior chamber depth (ACD), keratometry (K1 and K2), and white-to-white (WTW) were compared using a Lenstar LS900 optical biometer before and after induction of cycloplegia with 1% cyclopentolate. The IOL power was also compared using six different formulas (Barrett Universal II, Haigis, SRK/T, Hoffer Q, Holladay, and SRK-II) for the AcrySof MA60AC IOL before and after induction of cycloplegia.

Results: There were no statistically significant differences in AL, K1 and K2, or WTW measurements before and after induction of cycloplegia. There was a significant increase only in ACD from the biometric parameters after the induction of cycloplegia (p < 0.05). Despite this change, there were no significant changes in IOL power calculations using the six different formulas before and after induction of cycloplegia.

Conclusions: This study demonstrated that IOL power measurements using the Lenstar LS900 can be performed after cycloplegia.

单眼麻痹对光学低相干反射生物计的影响。

目的:比较成人睫状体麻痹诱导前后使用Lenstar LS900生物计进行光学低相干反射测量的生物测量结果和不同的人工晶状体度数计算公式。材料与方法:本横断面研究纳入健康志愿者168只眼，年龄40 ~ 86岁(59.22±11.57)。使用Lenstar LS900光学生物计比较1%环戊酸盐诱导睫状体麻痹前后的生物特征测量，包括轴长(AL)、前房深度(ACD)、角膜测量(K1和K2)和白对白(WTW)。采用Barrett Universal II、Haigis、SRK/T、Hoffer Q、Holladay和SRK-II六种不同配方对acryysof MA60AC人工晶状体诱导睫状体麻痹前后的人工晶状体度数进行比较。结果:脑瘫诱导前后AL、K1、K2、WTW测定差异无统计学意义。结论:本研究表明，在睫状体麻痹后，使用Lenstar LS900进行IOL度数测量是可行的。
