Topcon KR 8000 Autorefractor Keratometer — Used Rotary Prism Refraction and Keratometry

The Topcon KR 8000 is a combined autorefractor and keratometer that captures sphere, cylinder, axis, and corneal curvature in a single exam step. The Topcon KR 8000 is built on Topcon’s Rotary Prism Measuring System, which uses an off-centered ring target to read through pupils as small as 2.0 mm — useful with glaucoma patients on miotics, asymmetric pupils, and elderly patients. Refraction covers -25 D to +22 D sphere and up to ±8 D cylinder, while keratometry reads corneal radii from 5.00 to 10.00 mm. With a built-in thermal printer and a data terminal for serial output, the Topcon KR 8000 gives a busy pre-test lane a dependable objective starting point at a used price.

A study in Optometry and Vision Science (National Library of Medicine) evaluated the reliability of automated refraction and keratometry measurements, supporting the role of objective autorefraction and keratometry in routine pre-testing workflows.

Why Practices Choose the Topcon KR 8000

Proven Topcon optics, a small-pupil measuring system, and an integrated printer make the KR-8000 a practical workhorse for refraction and keratometry pre-testing.

• Rotary Prism Measuring System — Topcon’s rotary prism principle samples a wider fundus area for consistent, highly reliable refraction readings.
• 2.0 mm minimum pupil diameter — the off-centered ring target measures areas that a small pupil would otherwise block, reducing the need to dilate before autorefraction.
• Autorefractor + keratometer in one — sphere, cylinder, axis, and K-readings come from one instrument, so there is no separate keratometer to buy, calibrate, or find room for.
• Wide refraction range — -25 D to +22 D sphere and 0 to ±8 D cylinder in 0.12 D / 0.25 D steps cover high myopes and hyperopes alike.
• Full keratometry mode — corneal radius 5.00–10.00 mm (67.50–33.75 D) and corneal astigmatism up to ±10 D across a 3 mm measuring zone.
• Built-in thermal printer — instant hard-copy results for the chart or the optical dispensary without a separate printer.
• Joystick operation with on-board monitor — a familiar Topcon layout that technicians learn quickly.

Clinical Applications

• Routine refraction starting point — an objective sphere/cylinder/axis reading shortens subjective refinement at the phoropter.
• Cataract pre-operative screening — K-readings and refraction support the surgical work-up alongside dedicated biometry.
• Contact lens fitting — corneal radius and astigmatism values guide base curve and toric lens selection.
• Small-pupil and glaucoma patients — the 2.0 mm pupil capability helps obtain readings on miotic or elderly patients without dilation.
• High-volume screening days — fast, non-contact measurements keep pre-test lanes moving.

Who This Is For

• Optometry and ophthalmology practices that want proven Topcon autorefraction and keratometry at a used price point.
• Multi-location groups and satellite offices equipping an additional pre-test lane on a budget.
• Optical retailers with exam lanes that need one instrument to replace a separate autorefractor and keratometer.
• New practices building their first pre-test room with reliable, easy-to-service equipment.
