DGH 55 Pachmate Pachymeter — Used Ultrasonic Pachymeter
The DGH 55 Pachmate pachymeter is a compact, handheld ultrasonic instrument that delivers fast, reproducible central corneal thickness (CCT) readings at the chairside. Its detachable, adjustable-angle solid-state probe lets clinicians reach the cornea comfortably regardless of patient positioning, while the on-board display shows the running average and standard deviation of each measurement set as it is taken.
Because corneal thickness directly influences applanation tonometry, a reliable DGH 55 Pachmate pachymeter reading is a core part of glaucoma risk assessment, ocular hypertension evaluation, and pre-refractive-surgery screening. The instrument stores up to 25 bilateral measurements, so a practitioner can move between exam rooms without stopping to record results by hand.
Research on ocular biometrics reported in the National Library of Medicine confirms that corneal thickness is a measurable determinant of intraocular pressure readings and a risk factor for ocular hypertension, underscoring why routine pachymetry belongs in the glaucoma workup.
Why Practices Choose the DGH 55 Pachmate
- Handheld portability — at roughly 3.6 oz and under 7 inches long, the unit travels easily between lanes and satellite offices.
- Adjustable-angle probe — the detachable solid-state probe pivots to meet the cornea squarely for consistent, repeatable placement.
- Fast averaged readings — each measurement set displays a running average and standard deviation, so the operator sees measurement quality in real time.
- On-board memory — stores up to 25 bilateral measurements for rapid, back-to-back patient testing.
- High resolution — 1 micron display resolution with plus or minus 5 micron accuracy across a 200 to 1100 micron range.
- Simple operation — battery-powered, single-purpose design keeps training and daily use straightforward for any technician.
Clinical Applications
- Glaucoma risk stratification, where corneal thickness helps interpret measured intraocular pressure.
- Ocular hypertension monitoring and long-term follow-up of borderline patients.
- Pre-operative screening for LASIK, PRK, and other corneal refractive procedures.
- Assessment and monitoring of corneal edema and endothelial function.
- Baseline pachymetry before and after corneal or cataract surgery.
Who This Is For
- Ophthalmology and optometry practices building or expanding a glaucoma diagnostic workflow.
- Refractive surgery centers that need dependable pre-operative corneal measurements.
- Mobile and satellite clinics that require a portable, chairside pachymeter.
- Practices seeking a proven, cost-effective handheld pachymeter as a first or backup unit.
