第七节非接触眼压计检查法
非接触眼压计通过气体脉冲力将气体喷射到角膜中央部，使直径3.6mm范围的角膜压平。
通过监测系统接受角膜表面反射的光线，记录角膜压平到一定程度的时间，将其换算为眼压值。
测量方法：患者颏部置颏架上，前额紧靠头部固定器，调整坐椅高低及位置。
双眼要自然睁开，向前平视。
嘱受检眼注视测压头。
开机，患者被检查眼盯住仪器内的定位光点，检查者调节焦点至监视屏上出现自动测量信号，系统即自动发出一阵气体压平角膜，监视屏上自动显示眼压值和几次测量的平均值。
同上述方法，测量另眼，非接触眼压计自动打印结果，交给患者，最后关机。

4.眼球开放性损伤者。
【操作方法及程序】1.以X-Pert 非接触眼压计为例说明操作方法和程序。
2.受检者坐于非接触眼压计之前，嘱将其头部固定于眼压计头架上，向前注视，尽量睁开睑裂。
3.调节调焦手柄，将眼压计测压头对准待测眼角膜，此时眼压计监视屏上自动显示待测眼眼别。
4.在眼压计控制板上选择“ auto ”系统进行自动测压。
嘱受检眼注视测压头内的绿色注视灯，调节焦点至适当时，监视屏上两个方框重叠，系统自动发出一阵气体压平角膜，监视屏上自动显示出眼压值和几次测量的平均值。
如果受检者欠合作，或测量方法有误，所显示的数值自动标上“ * ” 号，或不显示数值。
5.也可在控制板上选择“ man",此时对焦后需手按调焦手柄上开关才能测量眼压。
6.测量完成后在控制板上按“ print" ，可将测量结果打印出来。
【注意事项】1.非接触眼压计与Goldmann 压平眼压计相比，在正常眼压范围内的测量值是可靠的，但在高眼压时其测量值可能出现偏差，角膜异常或注视困难的受检者中可能出现较大误差。
2.由于测压时非接触眼压计不直接接触眼球，因而减少了应用其他眼压计测压可能引起的并发症，如角膜擦伤、对表面麻醉药过敏和播散感染。
但对角膜异常者应慎用，因为不但测量值可能不准确，而且还可能引起角膜上皮下气泡。
由于测压头前表面污染而引起感染播散也已有报道。

QuickPulse mode can be toggled onand off by pressing the button, the QuickPulse Indicator illuminates if themode is active.The QuickPulse facility should only be used when necessary.QuickPulse can also aid in training new operators. They may have difficulty initially in obtaining the correct focus (refer to the pull out instructions,located underneath the Pulsair EasyEye).Getting StartedBefore you can start to use your Pulsair EasyEye, follow the proceduresoutlined below.1.Remove the hand unit from the base unit. Turn the Pulsair EasyEyeover to display the label and transit knob.The label displays the IEC and CE classifications for the PulsairEasyEye, and also the serial and part numbers which will be requiredfor registration and re-ordering.2.Remove the transit knob from the bottom of the Pulsair EasyEye unit asinstructed by the label.Note:The transit knob should be replaced whenever the unit is transported.3.Take the power supply unit and replace the blanking plate with theappropriate mains plug adapter. Alternatively you can use an I.E.C.60320 Type 7 extension lead (not supplied), see your local distributorfor more details.Patient PreparationBefore using the Pulsair EasyEye you should make your patient feel at ease and ensure they are located in an optimum reading location. This isbecause apprehension and nervousness may adversely affect the readingsobtained. Follow the points outlined below to achieve this:•Ask the patient to switch their mobile telephone off if they have one.•Ensure that the patient is comfortable and in a relaxed position.•Ask the patient to remove their contact lenses or spectacles if worn and to blink normally.In order to reassure the patient, you can demonstrate the procedure onthe back of the patient's hand prior to taking a reading:•Position the hand unit above the patient's hand and press Demo.The patient experiences a gentle puff of air.Before taking a reading you should:•Ensure the patient and instrument optics are not positioned under direct lighting (i.e. spot lights or sunlight).•Ensure the patient’s eyes are fully opened. This helps to prevent squeezing, where the patient unconsciously tenses their eyelids andincreases IOP.Throughout the reading process, you should:•Allow the patient to blink at intervals in order to maintain the corneal tear film.Instrument Preparation1.Plug the power supply in to the Pulsair EasyEye unit.2.Turn the On/Off switch to l, the status indicator on the front of theunit luminates green.

非接触眼压计
非接触眼压计介绍：
非接触眼压计(NCT)以其操作简便、测量迅速、自动打印检测结果、不直接接触眼球、不用表面麻醉、患者无任何痛苦等优点逐渐被越来
越多的患者认可和接受。
非接触眼压计正常值：
当3次眼压值相差>3mmHg或测得的眼压值带“[]”时应重新测量。
如患者无视力，可嘱其自然平视前方。
若患者瞳孔上移或下移时，嘱
其稍向下或向上注视。
非接触眼压计临床意义：
异常结果：由于不了解其方法，可产生紧张恐惧心理。
而紧张恐
惧情绪会引起神经调节失常、睫状肌痉挛，睫状体及虹膜的血管充血，使眼压升高而影响眼压的真实性。
需要检查人群：眼睛有问题者。
非接触眼压计注意事项：
不合宜人群：没有特殊说明。
检查前禁忌：情绪切忌紧张。
检查时要求：配合医生。
非接触眼压计检查过程：
1)检测开始前，打开检测喷嘴上的保护盖，然后打开电源开关和N CT工作键，使NCT进入预备状态。
2)指导患者面向眼压计坐好，两眼自
然平视，将下颚固定于下支架上，前额紧贴上支架板，调整支架高度，使眼睛与NCT喷嘴在同一高度上，同时调试被检眼的焦距，根据需要选
择NCT自动或手动功能键开关，嘱患者精神集中，尽量睁大眼睛注视检
测喷嘴内的红色亮点。
护士转动操纵杆，当眼压计的焦距与瞳孔的亮
点重叠且清晰时，NCT即自动喷气，显示屏上就显示所测数值，连测3次，取平均值。
然后按以上程序完成对另一眼的检测。
