Rebound Tonometer Portable Best Price in India
Rebound Tonometer - ERT1 | Eyevis
The ERT1 Rebound Tonometer is a portable handheld device designed to measure intraocular pressure (IOP), a key factor in diagnosing and managing glaucoma. Using a gentle probe that briefly contacts the eye’s surface, it delivers fast, accurate, and non-invasive pressure readings without requiring anesthesia or air puffs. Its user-friendly design makes it ideal for both clinical settings and at-home use.
How does rebound tonometry work?
Rebound tonometry is a quick, non-invasive method to measure intraocular pressure (IOP) without the need for anaesthetic drops or fluorescein dye. It uses a lightweight, handheld device—ideal for use without a slit lamp or headrest, saving time during appointments.
A tiny disposable probe with a magnetised steel shaft and a soft plastic tip is used for each patient. When the measurement button is pressed, the probe briefly touches the cornea and rebounds instantly. A solenoid inside the device detects this motion and converts it into electrical signals, which are analysed to determine eye pressure.
The higher the IOP, the faster the probe bounces back and the shorter the contact time. The device takes six quick measurements and averages them for accuracy. Because of its ease and speed, rebound tonometry is especially useful for children or patients who may have difficulty maintaining head positioning.
Quickness
The measurement process is extremely quick, delivering results in just 0.1 seconds with instant data display.
Comfort
No need for epidural anaesthesia or chemicals—providing fast, accurate measurements with maximum patient comfort. Offers 200° of positional flexibility, allowing assessments whether the patient is standing, sitting, reclining, or lying flat.
Accuracy
The data display includes statistical p-values with a precision of 0.1 mmHg, ensuring highly accurate and reliable measurements. It outperforms NCT devices and shows strong correlation with the Goldmann Applanation Tonometer (GAT).
Handful
Handheld device for convenient and easy operation, featuring automatic positional alignment with built-in guidance and an intuitive user interface. Designed for both right- and left-handed users, it requires no specialised skills—simply load, align, and measure.
Safety
The professional disposable probe ensures safe and hygienic contact with the cornea, reducing the risk of cross-infection. Its single-use design prevents contamination, while the minimal contact area helps protect the cornea from damage.
Dexterity
Compact size, portable and easy to store.
