Non-Contact Tonometer
Non-Contact Tonometer is an advanced diagnostic device used in eye care to measure the biomechanical properties of the cornea. The cornea is the clear, dome-shaped tissue that covers the front of the eye, and it plays a crucial role in the eye's ability to focus light.
非接觸式眼壓計是一種先進的診斷設備,用於測量角膜的生物力學特性。角膜是覆蓋眼睛前部的透明圓頂形組織,對眼睛聚焦光線起著至關重要的作用。
The Non-Contact Tonometer measures several parameters of the cornea, including corneal hysteresis (CH) and corneal resistance factor (CRF). CH is a measure of the cornea's ability to absorb and dissipate energy when subjected to an external force, such as the pressure from an air puff during a standard eye exam. It is thought to be related to the elasticity and damping properties of the cornea. CRF, on the other hand, is a measure of the overall resistance of the cornea to deformation and is thought to be related to the structural integrity of the cornea.
非接觸式眼壓計測量了角膜的幾個參數,包括角膜滯後(CH)和角膜阻力因子(CRF)。CH是角膜在外部力量作用下吸收和消散能量的能力的一種測量方法,例如標準眼部檢查中空氣噴射所施加的壓力。它被認為與角膜的彈性和阻尼特性有關。另一方面,CRF是角膜整體抵抗變形的測量方法,被認為與角膜的結構完整性有關。
The Non-Contact Tonometer also measures intraocular pressure (IOP), which is the pressure inside the eye. There are two methods of measuring IOP using the Non-Contact Tonometer: Goldmann-correlated intraocular pressure (IOPG) and corneal-compensated intraocular pressure (IOPcc). IOPG is a measure of intraocular pressure as determined by the traditional Goldmann applanation tonometry method. IOPcc, on the other hand, is a newer method of measuring intraocular pressure that takes into account the biomechanical properties of the cornea and adjusts for its thickness and rigidity.
非接觸式眼壓計還測量了眼內壓力(IOP),即眼內部的壓力。使用ORA測量IOP有兩種方法:Goldmann相關眼內壓力(IOPG)和角膜補償眼內壓力(IOPcc)。IOPG是通過傳統的Goldmann准直測壓法測量眼內壓力的方法。另一方面,IOPcc是一種新的測量眼內壓的方法,它考慮了角膜的生物力學特性並根據其厚度和剛度進行了調整。
By measuring CH, CRF, IOPG, and IOPcc, the Non-Contact Tonometer provides a more comprehensive assessment of the health of the cornea and the intraocular pressure of the eye. This information can be particularly useful in the diagnosis and management of conditions such as glaucoma, where accurate measurement of intraocular pressure is essential for effective treatment.
通過測量CH、CRF、IOPG和IOPcc,ORA提供了對角膜健康和眼內壓力的更全面的評估。這些信息在診斷和治療青光眼等疾病時尤為有用,其中準確測量眼內壓力對有效治療至關重要。
In addition to glaucoma, Non-Contact Tonometer can also be used to monitor the health of the cornea and the effects of corneal surgeries, such as LASIK. By providing a more comprehensive assessment of the cornea, the ORA can help eye care professionals make more informed decisions about the best course of treatment for their patients.
除青光眼外,非接觸式眼壓計還可用於監測角膜的健康狀況和角膜手術(例如LASIK)的影響。通過提供對角膜的更全面評估,非接觸式眼壓計可以幫助眼科專業人員為患者做出更明智的治療決策。
Overall, Non-Contact Tonometer is an important tool for eye care professionals, providing valuable information on the biomechanical properties of the cornea and the intraocular pressure of the eye. Its advanced features and ability to provide a more comprehensive assessment of eye health make it a valuable addition to any eye care practice, helping to improve patient outcomes and prevent vision loss.
總之,非接觸式眼壓計是眼科專業人員的重要工具,提供有關角膜的生物力學特性和眼內壓的有價值信息。其先進功能和提供更全面的眼部健康評估能力,使其成為任何眼科醫療實踐的寶貴補充,有助於改善患者的治療效果並預防視力喪失。
