Condition & Warranty
Used. This Topcon KR-800PA has been inspected and function-tested across autorefraction, automated keratometry, and Placido corneal topography modes. Refraction measurement, K1/K2 keratometry, and corneal topography map generation confirmed operational. Auto-tracking and auto-shot function verified. Covered by a 90-day warranty on parts and workmanship through Digital Eye Center.
Topcon KR-800PA — Used 3-in-1 Autorefractor, Keratometer & Placido Corneal Topographer
The Topcon KR-800PA is a combined autorefractor, automated keratometer, and Placido disc corneal topographer — measuring objective refraction, flat and steep keratometry values, and full anterior corneal topography in a single non-contact instrument that eliminates the need for separate autorefractor and topographer equipment in the examination lane. This used Topcon KR-800PA delivers the combined refraction-keratometry-topography workflow needed for efficient pre-surgical screening, contact lens fitting, and astigmatism management in comprehensive ophthalmology and optometry practices.
The Topcon KR-800PA uses an 8-ring Placido disc to generate the corneal topography map that goes beyond single-point keratometry — revealing the full anterior corneal surface profile needed to identify irregular astigmatism, early keratoconus, and post-refractive surgery corneal changes that flat/steep K values alone cannot detect. Research published in Optometry and Vision Science (National Library of Medicine, 2013) demonstrated that automated keratometry measurements directly influence toric IOL selection — confirming that the accurate automated K readings and corneal topography that the Topcon KR-800PA provides are clinically determinative for astigmatic cataract surgery planning and refractive outcomes.
Why Practices Choose the Topcon KR-800PA
- 3-in-1: autorefractor + keratometer + corneal topographer — Objective refraction (sphere, cylinder, axis), automated keratometry (K1, K2, corneal astigmatism axis), and Placido disc corneal topography are acquired in a single instrument — replacing two or three separate instruments with one compact unit that reduces equipment cost and exam room footprint without sacrificing measurement capability.
- Placido disc corneal topography (8-ring) — The PA’s 8-ring Placido disc maps anterior corneal curvature across the full optical zone, producing color-coded topography maps that identify irregular astigmatism, keratoconus, pellucid marginal degeneration, and post-surgical ectasia risk that single-point keratometry cannot detect.
- Automated non-contact measurement — Auto-tracking and auto-shot technology captures refraction and keratometry without operator finger-on-the-button timing, ensuring consistent measurement alignment across different technicians and reducing per-patient measurement time in busy pre-testing workflows.
- Corneal diameter measurement — White-to-white corneal diameter measurement at the time of refraction and keratometry provides the dimension needed for contact lens diameter selection and phakic IOL sizing without a separate measurement step.
- Pupil diameter measurement — Photopic and mesopic pupil diameter measurements at the time of refraction assessment support refractive surgery candidacy screening and premium IOL selection by identifying patients whose large scotopic pupils exceed the optical zone of planned IOL or LASIK treatment.
- Integrated display and output — Topography maps, keratometry values, and objective refraction are displayed together on the instrument monitor, enabling the pre-testing technician to identify significant findings (irregular astigmatism, high astigmatism, large anisometropia) and flag them for physician review before the examination begins.
- Topcon platform reliability — Topcon has manufactured autorefractors and keratometers for over 60 years; the KR-800 platform’s robust mechanical construction and straightforward service access make it one of the most maintainable combined autorefractor-keratometers in clinical use.
Clinical Applications
- Pre-surgical cataract screening — Automated keratometry and Placido topography together screen for irregular corneas, keratoconus, and post-refractive surgery changes before cataract workup — identifying patients requiring modified IOL formulas or non-standard lens selection before expensive diagnostic testing is performed.
- Toric IOL candidate identification — Automated keratometry magnitude and axis from the KR-800PA identifies cataract patients with clinically significant corneal astigmatism (≥0.75 D) who benefit from toric IOL implantation, and provides the K data for toric IOL power calculation with the Topcon corneal astigmatism axis for alignment marking.
- Refractive surgery screening — Placido topography maps screen LASIK and PRK candidates for keratoconus, irregular astigmatism, and asymmetric bow-tie patterns that contraindicate laser vision correction — providing the topographic screening required in every refractive surgery pre-operative protocol.
- Contact lens fitting — Corneal curvature (K1, K2) and corneal topography together guide base curve selection for spherical soft, toric, and rigid gas-permeable lenses, and corneal topography maps identify irregular corneas requiring scleral or specialty lens designs that flat/steep K values alone would not reveal.
- Keratoconus detection and monitoring — Serial Placido topography maps document keratoconus progression over time, with the topographic irregularity indices and K-max values that guide crosslinking referral decisions in progressive keratoconus suspects.
- Routine pre-testing refraction — Objective refraction from the autorefractor provides the starting point for manifest refraction in every comprehensive examination, reducing chair time by presenting an accurate objective prescription for the clinician to refine during subjective testing.
Who This Is For
- Comprehensive ophthalmology and optometry practices needing both autorefraction and corneal topography — the Topcon KR-800PA combines both instruments in one footprint at a price below purchasing a separate autorefractor and standalone topographer, without sacrificing the Placido topography capability needed for cataract and refractive screening.
- Cataract practices screening for toric IOL candidates and post-refractive surgery IOL planning — the combined automated K and Placido topography in a single pre-testing step provides the corneal data needed for toric IOL selection without diverting patients to a separate topography unit.
- Refractive surgery programs performing pre-LASIK/PRK screening — Placido topography is required in every refractive surgery pre-operative protocol; the KR-800PA delivers this capability combined with autorefraction in the same instrument that performs routine pre-testing.
- Contact lens specialty practices fitting specialty lenses — combined refraction, keratometry, and Placido maps provide the complete fitting data set for RGP, scleral, orthokeratology, and post-surgical specialty lens fitting from a single instrument.
- Practices replacing aging autorefractors — the used Topcon KR-800PA at $9,350 upgrades a practice from a keratometry-only autorefractor to a combined refractor-keratometer-topographer, adding corneal topography capability to the pre-testing workflow without the capital outlay of a separate standalone topographer.
