Topcon KR 8800 Autorefractor / Keratometer with CT-80 Tonometer — Used
This used Topcon KR 8800 package pairs a Rotary Prism auto refractor/keratometer with a matching Topcon CT-80 non-contact tonometer, so one purchase covers objective refraction, corneal curvature, and intraocular pressure for a pre-test lane. The Topcon KR 8800 (often searched as KR8800) measures sphere from −25D to +22D, cylinder up to ±10D, and corneal radii from 5.00 to 10.00 mm, and it works through pupils as small as 2.0 mm. Results appear on a color LCD and print on the built-in thermal printer, so the technician hands a printout straight to the doctor.
The Topcon CT-80 completes the station with air-puff IOP measurement from 0 to 60 mmHg (0–30 / 0–60 mmHg selectable), an 11 mm working distance, and selectable automatic or manual measurement. A clinical study indexed by the National Library of Medicine assessed the accuracy and reliability of the Topcon CT80 non-contact tonometer for IOP measurement.
Why Practices Choose the Topcon KR-8800 and CT-80

- Rotary Prism Technology — Topcon’s rotating-prism optics deliver consistent objective refraction, even on small pupils down to 2.0 mm.
- Refraction and keratometry in one instrument — the KR-8800 captures refractive error and K-readings at the same station, without moving the patient to a separate keratometer.
- Wide measurement range — −25D to +22D sphere, up to ±10D cylinder, and 5.00–10.00 mm corneal radius cover routine and high-ametropia patients.
- Non-contact IOP screening — the CT-80 measures pressure with a soft air puff, so no topical anesthetic is needed.
- Dual-sensor tonometry — the CT-80 uses one light sensor and one pressure sensor for each reading.
- Triple safety function — an adjustable safety stopper plus visual and audible “too close” warnings on the CT-80.
- Printed results on both units — each instrument has a built-in printer for a hard copy at the lane.
- Two-instrument flexibility — as separate units, the autorefractor and tonometer can share one lane or be split between two pre-test stations.
Clinical Applications
- Objective refraction as a starting point for subjective refinement in optometric and ophthalmic clinics.
- Keratometry for contact-lens fitting and corneal curvature assessment.
- Routine non-contact IOP screening during comprehensive exams and glaucoma work-ups.
- Technician-run pre-test stations that prepare patients before the doctor’s exam.
- Secondary or satellite lanes that need both refraction and IOP screening.
Who This Is For
- Optometry and ophthalmology practices equipping a pre-test lane on a controlled budget.
- Clinics that already use Topcon instruments and want a familiar workflow.
- New or expanding practices that need autorefraction, keratometry, and tonometry in one purchase.
- Buyers looking for a tested used autorefractor/keratometer bundled with a non-contact tonometer.
