EAT 1 Applanation Tonometer
The EAT 1 Applanation Tonometer is a device used to measure intraocular pressure (IOP) by flattening a small part of the cornea. It is commonly used in diagnosing and managing glaucoma. The tonometer provides accurate pressure readings by applying a controlled force to the eye’s surface, typically requiring the use of anesthesia. This method is considered a gold standard for IOP measurement in ophthalmology.
Features
Accurate Measurement
With years of tests and clinical applications, Goldmann has been proved to be the gold standard for tonometry measurement. Based on the proven evidence, Eyevis EAP1 tonometer applied Goldmann principle in the design and manufacture. With precision manufacturing process, Eyevis applanation tonometer offers accurate and consistent measurements which give a clear picture of patients’ IOP situation to the doctors
Excellent Mechanic
Full attention is paid to every detail in the manufacture of Eyevis tonometers. Workers assemble every component carefully and check tight tolerances in weight to make sure the tonometer delivers consistent measurements
Premium Optics
The prism on the tonometer is the key to accurate measurement. In Eyevis, our skillful workers make these prisms with great care and follow strict quality standards. We offer 3 pcs of prisms in a standard package, making Eyevis tonometers durable for long-term use.
