Tear evaporation rate meter
Eye-VapoMeter
Easy and quick measurement of tear evaporation rate (TER).
Eye-VapoMeter – Easy-to-use tear evaporation rate meter
The Eye-VapoMeter is the first and only portable tear evaporation rate meter. Tear evaporation rate (TER) can change when suffering from dry eye syndrome or wearing contact lenses. Efficacy of eye drops or other treatments can also be followed by measuring TER.
The Eye-VapoMeter is based on proven technology capable of measuring very high evaporation rates (50-300 g/m²h), like TER quickly and without saturation. The instrument is designed to fit perfectly on the eye. The measurement is independent of instrument orientation and subject’s posture, that makes the measurements comfortable for the subject.
Benefits
- Rotatable adapter fits perfectly on the eye
- Short measurement time, typically 15-20 sec
- Wide measurement range up to 300 g/m²h without saturation
- Ready to use - no daily calibration required
- Closed chamber - non-sensitive to ambient airflows
- Fully portable and battery operated
- Wireless connection to PC

FAQs
Eye-VapoMeter measures tear evaporation rate (TER), providing an objective assessment of water loss from the ocular surface and tear film. The measurement is non-invasive, rapid, and suitable for repeated assessments in ocular surface research.
Tear evaporation rate is an important parameter in studies of tear film stability and ocular surface health. Increased tear evaporation may contribute to tear film instability, making TER measurements valuable in dry eye research and treatment evaluation.
Eye-VapoMeter is used in dry eye research, pharmaceutical studies, contact lens research, and evaluation of treatments intended to improve tear film stability. It also enables investigation of environmental and physiological factors that influence tear evaporation.
Yes. Eye-VapoMeter is based on Delfin’s proven closed-chamber technology, originally developed for transepidermal water loss (TEWL) measurements with a specialized adapted for ocular surface and tear film research. By utilizing the same closed-chamber measurement principle, Eye-VapoMeter provides objective tear evaporation measurements while reducing the impact of environmental conditions on the measurement results
For transepidermal water loss (TEWL) measurements, see VapoMeter® VX.
