Non Contact Tonometer
A Non-Contact Tonometer (NCT) is a specialized diagnostic device used in ophthalmology to measure intraocular pressure (IOP). This is a critical test for diagnosing and monitoring conditions such as glaucoma, which can lead to vision loss if left untreated. Unlike traditional tonometry methods, the NCT is painless, quick, and does not require direct contact with the eye, making it more comfortable for patients.The Non-Contact Tonometer is a groundbreaking tool in modern ophthalmology, offering a safe, efficient, and hygienic way to measure intraocular pressure. Its non-invasive nature, combined with speed and accuracy, makes it an indispensable device for eye care professionals. By enabling early detection of conditions like glaucoma, it plays a vital role in preserving vision and improving patient outcomes.

How Does a Non-Contact Tonometer Work?
The NCT uses a puff of air to flatten the cornea temporarily. This process is known as applanation tonometry. Here’s how it works step by step:
- Positioning: The patient rests their chin and forehead on a support, ensuring the eye aligns with the machine.
- Air Puff: A precise puff of air is directed at the cornea.
- Response Measurement: The machine measures the time and force required to flatten the cornea.
- IOP Calculation: Based on these parameters, the IOP is calculated and displayed on the device.
Since thereβs no physical contact with the eye, this method minimizes the risk of corneal abrasion and eliminates the need for anesthetic drops.
Non-Invasive Testing
- Uses air instead of physical contact to measure IOP.
- Comfortable and stress-free for patients of all ages.
Speed and Efficiency
- Provides accurate results within seconds.
- Ideal for high patient volume clinics.
Hygienic
- Eliminates the risk of cross-contamination since no contact is made with the eye surface.
Advanced Calibration
- Equipped with automated calibration for consistent and reliable measurements.
User-Friendly Interface
- Easy-to-use touchscreen displays and intuitive settings for healthcare professionals.
