Applanation Tonometer TW-2430T: Instrument for measuring intraocular pressure or a high-power indirect examination lens used with a slit lamp for fundus and vitreous viewing.
What a tonometer does in your practice
Measuring intraocular pressure (IOP) is how glaucoma is caught early, so a tonometer belongs in every optometry practice that examines eyes. Applanation tonometers mounted on a slit lamp are the clinical reference; handheld and non-contact types are quicker for screening.
What to look for
- Applanation (Goldmann type) for accurate, reference-grade readings on a slit lamp
- Handheld models for home visits and patients who cannot sit at a slit lamp
- Calibration and disinfection: check how easily the prism can be cleaned between patients

Frequently asked questions
Which tonometer should an optometry practice choose?
An applanation tonometer mounted on a slit lamp is the clinical reference for measuring eye pressure. A handheld tonometer is practical for home visits and patients who cannot sit at a slit lamp. Many practices use both.
How often does a tonometer need calibration?
Check the calibration regularly, following the manufacturer instructions, and always after the instrument has been moved or dropped. Clean and disinfect the part that touches the eye between every patient.
