Topcon KR-8800 Autorefractor / Keratometer with CT-80 Tonometer

The matched Topcon CT-80 non-contact tonometer completes the diagnostic station, delivering air-puff intraocular pressure measurement from 0 to 60 mmHg (selectable 0–30 / 0–60), with automatic and manual modes and its own built-in printer. An independent assessment published by the National Library of Medicine found the Topcon CT-80 to be an accurate and reliable non-contact tonometer for routine IOP screening. Together the two units form a compact anterior-segment workstation that moves patients from objective refraction through keratometry and IOP screening at one station.
Why Practices Choose the Topcon KR-8800 and CT-80
- Rotary Prism Technology — samples objective refraction over a small 2 mm pupil for reliable readings even on smaller or partially obscured pupils.
- Refraction and keratometry in one shot — the KR-8800 switches from refraction to corneal curvature without patient re-alignment, cutting exam time versus separate stations.
- Wide measurement range — −25D to +22D sphere and corneal radii 5.0–10.0 mm cover routine through complex prescriptions.
- Auto-start capture — fires automatically at optimal focus, reducing operator variability and speeding throughput.
- Non-contact IOP screening — the CT-80 measures pressure from 0 to 60 mmHg without touching the cornea, with automatic and manual modes.
- Built-in printers on both units — immediate hard-copy documentation of refraction, K-readings, and IOP at the lane.
- RS-232C output — connects each instrument to EMR and lane-management systems for paperless workflows.
- Wide-range power supply — 100–240V, 50/60Hz operation suits domestic and international deployment.
Clinical Applications
- Objective refraction as a starting point for subjective refinement in high-volume optometric and ophthalmic clinics.
- Keratometry for contact-lens fitting and pre-operative corneal assessment.
- Routine non-contact IOP screening for glaucoma work-ups without topical anesthetic.
- Pre-test stations that prep patients before the physician exam.
- Satellite and secondary lanes that need a compact refraction-plus-IOP setup.
Who This Is For
- Ophthalmology and optometry practices building or expanding a refraction lane on a controlled budget.
- Clinics standardizing on Topcon instrumentation and workflow.
- Mobile and multi-site practices that need a proven, printer-equipped refraction and IOP station.
- Buyers seeking a tested used autorefractor/keratometer paired with a non-contact tonometer.
