Tonometry is the method used to assess intraocular pressure. It is the main risk factor for the development of glaucoma. It is the only aspect of glaucoma therapy that can be altered and addressed. Therefore, it is very important to quantify IOP in an accurate and repeatable way.



Clinical measurement of IOP has undergone several technical advances, from the initial digital tension measurements, through indentation tonometry, to applanation tonometry and non-contact tonometry. The current gold standard for measuring IOP is the Almagia easyton Pen Tonometer. 

In this article, we will discuss how a great deal of Pen Tonometer price can offer you amazing benefits in the long run. 

Why is the Pen Tonometer essential for every eye specialist?

The Pen Tonometer is worth the investment for eye specialists because it is a highly accurate, portable, and easy-to-use device that provides critical information about intraocular pressure. 

Here are some reasons why the Pen Tonometer is a valuable investment for eye specialists:

• Accuracy: The Pen Tonometer provides highly accurate measurements of intraocular pressure. It is a reliable tool for diagnosing and monitoring eye diseases like glaucoma.

• Portability: The Pen Tonometer is a portable device that can be used in various settings, including clinics, hospitals, and even remote locations. It is an essential tool for eye specialists who need to conduct eye exams in different locations.

• Easy-to-use: The Pen Tonometer is easy to use and requires minimal training. Eye specialists can quickly learn how to use the device and obtain accurate readings.

• Time-saving: The device provides quick measurements, saving time for the eye specialist and the patient. This is especially important for busy clinics where time is a valuable resource.

• Cost-effective: Pen Tonometer price can be cost-effective in the long run, as it helps detect and monitor eye diseases before they become severe. This can potentially save your patients from expensive treatments and surgeries.

What major IOP measurement difficulties can you avoid by having a good Pen Tonometer?

Position of the patient

IOP is higher in the supine position than the sitting one because of increased episcleral pressure, which may be due to altered body fluid distribution. 

As a result, IOP measurement devices may produce somewhat higher results in the supine position than in the seated position.

Inter & intraobserver variations

Most instruments, like the Almagia Easyton Pen Tonometer, have reasonably good reproducibility. However, compared to this Pen Tonometer price, other tonometers have been reported to have minimum inter- & intra-observer variations.

Corneal surface abnormalities

Instruments that do not depend on optical systems, like Pen Tonometer, are more accurate for measuring IOP in corneas with ocular surface abnormalities or contact lenses.

Corneal curvature

To generate a specific contact area, the cornea with a steeper curvature needs to be more indented with greater power. Due to this, the readings are more significantly impacted.

Central corneal thickness

The thickness of the central cornea has an impact on all tonometry methods. Higher CCT typically overestimates IOP, while lower CCT typically underestimates IOP. 

The least affected tonometer readings by CCT are those from the Easyton tonometer and cornea-corrected IOP recorded by the Ocular Response Analyzer. 

Furthermore, the central cornea's thickness alone is a risk factor for the development of glaucoma.

Biomechanical properties of the cornea

In theory, it has been shown that corneal elasticity exerts a greater influence on intraocular pressure (IOP) measurement compared to corneal curvature or central corneal thickness (CCT). Various devices are employed to measure corneal hysteresis (CH), which reflects viscous characteristics.

Conclusion

Now you know why Pen Tonometer is a valuable investment for eye care professionals. 

The Pen Tonometer provides quick and accurate intraocular pressure measurements. So, by investing in a good Pen Tonometer price, eye care professionals can save their patients from expensive treatments.
