SW-500 portable tonometer is based on the principle of dynamic induction. Its core function is to calculate the intraocular pressure value through the deceleration of the magnetized probe after hitting the cornea, combined with the design of the disposable probe, which considers safety and accuracy.
Portable tonometer Features:
1. Non-invasive, non-anesthetic, rapid intraocular pressure measurement
Operation process: Install the probe → Close to the eye → Press the button to complete 6 instantaneous measurements (about 0.1 seconds/time→ Automatically display the average value. )
Scope of application: - Human beings (including children, dementia patients, corneal edema or unevenness);
- Animal ophthalmology experiments (e.g. rabbits, pets) without anesthesia.
2. Data management and compatibility
- Stores nearly 10 patient data and supports wireless infrared printing
3. Wide application scope
Postoperative monitoring: After vitrectomy (inert gas or silicone oil filled eyes), the results are highly consistent with Goldmann tonometry (GAT), solving the problem of difficult measurement with traditional equipment;
Home self-test: Glaucoma patients can use it at home to reduce the cost of screening time.
