IOLmaster应用与操作

IOLmaster应用与操作

IOLmaster光学生物测量仪学习要点:激光干涉生物测量眼轴人工晶体度数计算晶体常数优化白到白测量第一节 概述一、光学生物测量的原理激光干涉生物测量(Laser Interference Biometry, LIB)是基于部分相干干涉测量(partial coherence interferometry, PCI)的原理,采用半导体激光发出的一束具有短的相干长度(160μm)的红外光线(波长780nm),并人工分成两束,那么这两束光具有相干性;同时,这两束光分别经过不同的光学路径后,都照射到眼球,而且两束激光都经过角膜和视网膜反射回来。

干涉测量仪的一端,是对准被测量的眼球,另一端有光学感受器,当干涉发生时,如果这两束光线路径距离的差异小于相干长度,光学感受器就能够测出干涉信号,根据干涉仪内的反射镜的位置(能够被精确测量),测出的距离就是角膜到视网膜的光学路径(图1)。

图1利用蔡司IOLMaster进行光学生物测量:眼球轴长是角膜前表面到视网膜色素上皮层的光学路径距离。

光学测量曲线显示光学感受器接受到与眼底位置相关的干涉信号曲线。

最强的峰值可以认为是视网膜色素上皮层;对称存在于峰值旁的是半导体激光的伪迹。

二、 IOLMaster光学生物测量仪从上世纪80年代始,激光干涉生物测量技术的图形形式——OCT逐渐得到眼科界的广泛认同。

而光学测量技术最近才由卡尔蔡司公司推出成熟的产品,它就是蔡司IOLMaster光学生物测量仪(图2)。

IOLMaster是一种为了计算人工晶体度数进行眼球轴长测量的全新仪器。

它创新的将角膜曲率、角膜直径白到白(white-to-white)、前房深度、眼球轴长的测量集中于一体,仅需非常微弱的光线即可准确地得出白内障手术所需要的数据;同时还提供充足数据广泛应用在眼轴长监测,前房型IOL植入术的前检查上。

IOLMaster眼球轴长的测量沿着视轴的方向,获得的是从角膜前表面到视网膜色素上皮层的光学路径距离。

IOL—Master测量硅油填充眼眼轴长及人工晶体度数的准确性研究

IOL—Master测量硅油填充眼眼轴长及人工晶体度数的准确性研究

IOL—Master测量硅油填充眼眼轴长及人工晶体度数的准确性研究摘要目的探讨采用光学相干生物测量仪IOL-Master测量硅油填充眼眼轴长及人工晶体度数的准确性。

方法拟行硅油取出联合白内障超声乳化摘除及人工晶体植入术的硅油眼患者36例(36只眼),使用IOL-Master测量并比较硅油取出前及术后1个月的眼轴长度,行玻璃体腔硅油取出联合白内障超声乳化摘除同时植入IOL-Master测量所得人工晶体度数,比较预估屈光度数与术后1个月电脑验光所测等效球镜值。

IOLMaster常见问题答疑

IOLMaster常见问题答疑

IOLMaster常见问题答疑本篇常见问题答疑仅做简单指南以便于正确和安全的操作,不可替代使⽤⼿册或者操作培训。

请联系蔡司公司的专业⼈员,了解并获取设备使⽤的培训。

在操作设备前请详细阅读说明书。

眼轴长度测量⾓膜曲率读数前房深度眼轴长度测量1. 在测量过程中需要注意哪些要点?⼀般⽽⾔:⾜够的泪膜层:在每次测量前,让患者眨眼⼀次。

让升降台、下颌托的⾼度,仪器的位置合适,以避免患者紧张和不必要的紧张。

在将仪器对准患者时(浏览模式下),仅需要粗略对准即可。

让患者盯住正前⽅的黄/红⾊的固视灯。

在眼轴测量时,询问患者是否能看见固视点。

眼轴长度测量:测量严重⽩内障患者时,让反射光点尽可能⼤——⼏乎和绿圈的直径⼀样(轴长测量和测量的距离⽆关)对核性⽩内障患眼测量时,让测量光偏离正中轴——垂直调整⽽不是⽔平调整,且使⽤⼩光点测量。

对提⽰“错误”信息的患者(致密⽩内障/后囊下致密混浊),或者信噪⽐在1.4~1.6 之间的患者,往往能够获得可靠的结果(如果5次测量的结果是⼀致的,那么这样的结果可以通过⼿动调整测量图像上的测量点来获得)。

如果测量的结果包含双峰或多峰,需要调整信号图像上的测量点(详情参考说明书)。

如果患者的屈光不正超过6 D,请患者戴上⾃⼰的眼镜进⾏测量。

这样患者能够更好的固视,⽽且能够提⾼信噪⽐,降低标准差。

但不允许佩戴接触镜进⾏测量——结果可能错误。

2. IOLMaster的结果和超声⽣物测量的可⽐性如何?测量结果的不⼀致是哪些测量⽅法带来的?超声⽣物测量的是⾓膜前表⾯到视⽹膜内界膜之间的距离。

⽽IOLMaster测量的是⾓膜前表⾯(严格意义上是泪膜层)到视⽹膜⾊素上⽪层之间的距离。

有⼤量的临床研究⽐较了这两种测量⽅法的不同之处。

IOLMaster仪器整合了“校正因⼦”软件,从⽽能够调整测量的结果和浸润式超声测量的结果⾼度相关,并且使⽤调整后的⼈⼯晶体常数,从⽽进⾏计算不会存在差异。

在进⾏接触式超声⽣物测量时,测量头对⾓膜的压迫效应(由于对⾓膜的压陷将减⼩前房深度100~300微⽶)需要考虑进去。

IOL Master对硅油取出前后眼轴及角膜曲率测量的临床研究的开题报告

IOL Master对硅油取出前后眼轴及角膜曲率测量的临床研究的开题报告

IOL Master对硅油取出前后眼轴及角膜曲率测量的临床研究的开题报告一、背景与意义:硅油注射是一种常见的眼部手术,如玻璃体切割术后使用硅油填充眼腔进行支撑和保护。

然而,硅油有时需要在手术后取出,此时眼轴和角膜曲率可能发生变化。

眼轴和角膜曲率是屈光度测量的重要参数,如果取出硅油后未及时重新测量,可能会影响眼球度数的精准测量,从而影响眼部手术的效果和疗效。

因此,研究硅油取出前后眼轴及角膜曲率测量的变化,可以为眼科医生提供更精准的眼部手术操作指导。

二、研究目的:本研究旨在探究硅油取出前后眼轴及角膜曲率的变化情况,并为玻璃体切割术后硅油取出后提供屈光度测量的科学依据,以便于对眼球度数的准确测量提供指导。

三、研究内容和方法:研究内容:1.研究对象:本研究随机选取30例玻璃体切割术后硅油注入的患者,观察其硅油取出后眼轴及角膜曲率的变化情况。

2.研究内容:使用IOL Master仪器进行眼轴和角膜曲率的测量,比较硅油取出前后的眼轴和角膜曲率的变化。

研究方法:1.实验设计:本研究采用前后对照的实验设计。

2.实验操作:使用IOL Master仪器对患者进行眼轴和角膜曲率的测量,分别在硅油注入前和取出后进行。

测量结果进行比较,并进行统计学分析,以确定眼轴和角膜曲率的变化情况。

四、预期结果:通过研究,预计可以得出以下结论:1.硅油取出后,眼轴和角膜曲率可能发生变化。

2.硅油取出前后眼轴和角膜曲率的变化可能存在差异。

3.本研究结果可以为眼科医生提供更精准的屈光度测量参考,有助于提高眼科手术的效果和疗效。

五、研究意义:随着眼科手术技术的不断发展,眼球度数的精准测量变得越来越重要。

本研究旨在探究硅油取出前后眼轴及角膜曲率的变化情况,为玻璃体切割术后硅油取出后提供屈光度测量的科学依据,有助于眼科医生更准确地进行眼球度数测量和手术操作,提高手术效果和治疗效果。

iol master 500测量原理

iol master 500测量原理
IOL Master 500是一种常用的眼科仪器,用于测量人眼内部晶状体的光学参数,以便为白内障手术选择合适的人工晶状体。

IOL Master 500的测量原理基于光间干涉测量技术。

具体而言,IOL Master 500使用光学相干层析扫描(Optical Coherence Tomography,简称OCT)技术来测量眼内各个结构的形态和位置。

当测量开始时,仪器会向眼中发送一束波长为780纳米的激光光源,并通过眼睛的角膜和晶状体,进入到眼底。

光线经过眼底后,一部分会反射回来,这些反射光与未反射光之间存在干涉现象。

IOL Master 500会探测这种干涉现象并对其进行分析。

它会测量反射光线的时间延迟和幅度变化,通过分析干涉光信号的特征来确定不同结构的位置、形态和厚度。

通过测量眼轴长度、前房深度、角膜曲率半径等参数,可以计算出眼内晶状体的光学参数,如晶状体厚度、前后表面曲率等。

总的来说,IOL Master 500利用光间干涉测量技术通过分析眼内反射光的干涉现象,获得眼部结构的形态和位置信息,从而实现对晶状体光学参数的测量。

这些测量结果对于人工晶状体的选择和白内障手术的准备非常重要。

的各项生理参数,为眼科医生提供诊断和治疗方案的依据。

下面我们将详
细介绍 iolmaster 报告单的组成部分,以及如何解读 iolmaster 报告单。

一、iolmaster 报告单概述
iolmaster 报告单,又称眼科光学相干断层扫描报告单,是一种通过眼科光学相干断层扫描仪(iolmaster)检查眼睛后产生的报告单。

iolmaster 是一种先进的眼科检查设备,可以对眼睛进行非接触式、无创
性的三维成像,从而获取眼睛的各项生理参数。

二、iolmaster 报告单的组成部分
iolmaster 报告单一般包括以下几个部分:
1.患者基本信息:包括患者姓名、性别、年龄、检查日期等。

2.检查仪器和参数:包括检查仪器名称(iolmaster)、检查模式、扫描范围、分辨率等。

3.检查结果:这是 iolmaster 报告单的核心部分,包括了眼睛的各
项生理参数,如角膜厚度、角膜地形图、眼轴长度、前房深度、晶体厚度等。

4.图像和数据分析:报告单上还会附带一些图像和数据分析,帮助医生更直观地理解检查结果。

三、如何解读 iolmaster 报告单
对于非专业人士来说,iolmaster 报告单可能显得有些复杂。

下面我们简单介绍一些常见的检查结果指标及其临床意义。

1.角膜厚度:角膜是眼球的前部结构,对眼睛的屈光力有重要影响。

角膜厚度的正常范围在 500-600 微米。

2.角膜地形图:反映了角膜表面的形状和特征,如角膜弯曲度、角膜扁平化等。

3.眼轴长度:眼轴长度是指眼球的前后径,与近视、远视等屈光不正有关。

正常成年人的眼轴长度在 23-24 毫米。

4.前房深度:前房是位于角膜和晶体之间的空间,前房深度的正常范围在 2.5-3.0 毫米。

5.晶体厚度:晶体是眼球内的透明结构,参与调节视力。

晶体厚度的正常范围在 4-5 毫米。

四、iolmaster 报告单的临床应用
iolmaster 报告单在眼科临床诊断和治疗中有广泛的应用,可以帮助医生了解患者的屈光状态、角膜形态、眼轴长度等重要信息,为近视、远视、散光等屈光不正的诊断和治疗提供依据。
