Ezer Applanation Tonometer ESL-Emerald-TN
The Japanese ESL-Emerald-TN tonometer is a precision application tonometer designed to mount onto slit lamp equipped stereomicroscopes used for measuring intraocular pressure (IOP). The ESL-Emerald-TN works by contacting the applanation measuring cone to the eye and slowly applying pressure to the corneal surface using the measurement until it temporarily flattens. The measuring cone determines the force needed to do so, providing IOP measurements that are key to diagnosing or assessing a patient’s risk of glaucoma. With its precision machining, accessibility, modular versatility, and patient comfort, the ESL-Emerald-TN is the perfect addition to slit-lamp microscopes in any clinic and makes taking IOP a snap.

The ESL-Emerald-TN tonometer packs quality construction and adaptability into a small modular device that can be mounted onto a slit-lamp stereoscopic microscope used in ocular imaging. While this attachment was designed with the ESL-Emerald microscope system in mind, the ESL-Emerald-TN can be added to many different microscopes from various manufacturers. This allows for unprecedented versatility and application in a wide range of clinical settings.
With a small applanation surface plane of only 3.06 mm in diameter and an area of 7.35 mm2, the ESL-Emerald-TN tonometer minimizes the amount of corneal contact and eyeball deformation needed to get a highly accurate reading. This ensures patient comfort and can help reduce the time per measurement, assisting operators in maintaining an efficient workflow without sacrificing the quality of patient care.
The ESL-Emerald-TN tonometer is designed with user experience at the forefront. There are no calibration or standardization difficulties to worry about; simply apply pressure until applanation is achieved and read the results directly from the device. An included quick reference table simplifies the conversion from the pressure of the measurement drum to IOP without the need for additional software or calculations.
High-quality precision-made optical components are key to the functionality of the ESL-Emerald-TN tonometer. Illumination from your chosen slit-lamp passes through the built-in cobalt filter before it passes through the plastic measuring prism, delivering reflection-free observation of split images.
