A Comprehensive Comparison Of Easyton Transpalpebral Tonometer And Perkins Applanation Tonometer In Measuring Intraocular Pressure

Intraocular pressure (IOP) measurement is critical to assessing ocular health, particularly in conditions like glaucoma. It is essential for eye professionals to have accurate and reliable measurements that are essential for appropriate diagnosis and management. 

However, new technologies, such as the Easyton transpalpebral tonometer, have provided an alternative to traditional applanation tonometry.

So, in this blog, we aim to comprehensively compare the IOP measurements obtained using Easyton tonometer and the Perkins application tonometer (PAT) across various demographic groups, shedding light on their suitability for different clinical populations.

The study included 84 subjects categorized into three groups: 22 healthy children (G1), 42 healthy adults (G2), and 20 adult patients with primary open-angle glaucoma (G3). In all cases, IOP was measured using both the Easyton eye care tonometer and PAT by an experienced examiner. Central corneal thickness (CCT), axial length (AL), age, sex, and gender were recorded for each participant.


The mean differences in IOP readings between Easyton and PAT varied across the groups, with the most notable difference observed in the glaucoma patients (G3). The correlations between IOP values obtained from Easyton and PAT were statistically significant, indicating a moderate to good agreement between the two tonometers. The intraclass correlation coefficients further supported the deal, signifying the reliability of both tonometry methods.

Comparison and Analysis

The analysis revealed that Easyton and PAT provided IOP measurements with an acceptable level of agreement, especially in healthy individuals. Easyton proved valuable for IOP screening in children and in cases where PAT measurements may be impaired, such as in patients with certain facial spasms, corneal irregularities, or reduced mobility. However, it was not recommended for glaucoma patients’ follow-up.

Moreover, according to this study, it helps eye professionals to understand the need of buying tonopen for sale, how it helps in getting accurate results as well as it helps in identifying glaucoma in patients as soon as possible. 

Easyton Tonometer – A Transpalpebral Approach

If you are looking for an eye pressure monitor for sale, you must go for an Easyton transpalpebral tonometer. This tonometer offers a unique transpalpebral approach for measuring intraocular pressure. This approach involves gentle contact with the eyelid, making it a non-invasive and patient-friendly method. 

The vibrational operating principle of Easyton ensures measurement stability and compensates for corneal thickness, resulting in precise IOP readings. This makes it particularly suitable for patients with challenging traditional application methods.

Perkins Applanation Tonometer – A Trusted Approach

The Perkins applanation tonometer (PAT) is a well-established and widely used applanation tonometry device. It provides accurate IOP measurements by gently touching the eye’s surface and flattening a small cornea area. 

Despite its effectiveness, PAT may face limitations in specific clinical scenarios, as highlighted in the study, emphasizing the importance of alternatives like Easyton.


The study underscores the significance of accurate IOP measurements and the importance of choosing the right tonometry method based on the patient’s clinical condition. 

Easyton and PAT have their merits, with Easyton demonstrating significant promise in specific scenarios, especially in pediatric and challenging cases. The comparative analysis provides valuable insights for ophthalmologists and eye care professionals, aiding them in selecting the most appropriate tonometry method for their patients.

Moreover the advancement in tonometry technology continues to enhance the accuracy and convenience of IOP measurements, ultimately benefiting patient care and improving outcomes in the realm of ophthalmic practice.
