一、工作原理(Working Principle)
中文
TONOREF III 是集自动验光、角膜曲率测量、非接触式眼压测量及角膜测厚于一体的多功能眼科检查设备。
验光(Refraction):采用大瞳孔区成像法,通过红外光源与高灵敏度 CCD,同时测量瞳孔中央(3.5mm)与周边(最大 6mm)的屈光力。内置自动雾视系统,先矫正散光再放松调节,确保测量。
角膜曲率(Keratometry):运用双迈尔环(Placido)投射技术,向角膜投射两个不同直径(3.3mm / 2.5mm)的环形光带,通过分析反射图像计算角膜曲率半径与屈光力,减少眼睑干扰。
眼压(Tonometry):非接触式气脉冲原理。设备向角膜发射气流,使角膜表面形变,通过光学系统检测形变时间与程度,换算为眼压值。并根据角膜厚度自动补偿校正眼压NIDEK。
角膜测厚(Pachymetry):利用红外光镜面反射原理,测量红外光在角膜前、后表面的反射波时差,精确计算中央角膜厚度。
English
TONOREF III is an integrated multi-functional ophthalmic instrument combining auto-refraction, keratometry, non-contact tonometry, and pachymetry.
Refraction: Adopts the Large Pupil Zone Imaging with an infrared light source and high-sensitivity CCD, measuring refractive power in both the central (3.5mm) and peripheral (up to 6mm) pupil areas simultaneously. An integrated auto-fogging system corrects astigmatism first to minimize accommodation.
Keratometry: Uses the Double Mire Ring (Placido) technology, projecting two concentric rings (3.3mm / 2.5mm) onto the cornea. Corneal curvature and refractive power are calculated by analyzing reflected images, reducing eyelid interference.
Tonometry: Based on non-contact air-puff technology. A precise air pulse deforms the cornea; optical sensors measure the time and degree of deformation to calculate IOP. It automatically provides a corrected IOP based on corneal thicknessNIDEK.
Pachymetry: Utilizes infrared specular reflection to measure the time difference of reflected waves from the anterior and posterior corneal surfaces for accurate central corneal thickness measurement.
