Reichert 7CR: Hospital-Grade Glaucoma Metrics in Your Practice

Every time you refer a glaucoma suspect and they come back from the hospital with a discharge letter, something is lost. Not just time. Your clinical credibility with that patient. The Reichert 7CR Auto Tonometer is built specifically to stop that from happening.

Inaccurate IOP readings are the leading cause of unnecessary glaucoma referrals. And the root of the problem is well understood: standard tonometry is sensitive to corneal thickness and biomechanical properties. A patient with an unusually thick or thin cornea, or one who has had LASIK or PRK refractive surgery, can return a misleading reading on a conventional non-contact tonometer. The result is a referral that the hospital eye service does not need, and a patient who loses confidence in your judgement.

The 7CR is designed to solve that problem at source.

What Corneal Response Technology actually does

The 7CR uses a patented bi-directional applanation process — a puff of air that measures the eye on the way in and on the way back. That two-way measurement allows the device to characterise the biomechanical properties of the cornea and account for them, rather than let them distort the result.

The output is IOPcc — Corneal Compensated IOP. This is the same pressure metric used in NHS ophthalmology clinics. Not a community-grade approximation. The same number your local hospital glaucoma clinic is working from. When you refer with IOPcc data, secondary care already understands the measurement. There is no translation required, no adjustment to be made. You are speaking the same clinical language.

The device also produces IOPg — Goldmann-correlated IOP — for practices that want to compare across both metrics. And a waveform score flags the reliability of each individual reading, so poor-quality measurements are identified and averaged out rather than recorded as fact.

No consumables. No drops. No contact.

The 7CR is fully non-contact. Patients lean against the forehead rest and the device handles everything — alignment, measurement, output — automatically. No anaesthetic drops, no disposable prisms, no cross-contamination risk. One-touch triple measurement mode. Internal printer. USB data transfer.

For a busy independent practice, that matters. No consumable costs means the running cost of the instrument is genuinely zero beyond the initial purchase and routine servicing. For practices currently using iCare or Goldmann, the cost comparison over a three-to-five-year period is worth doing. Grafton Optical provide a business case calculator on their product page for exactly that purpose.

The GIRFT connection — and why it matters for independents

GIRFT — Getting It Right First Time — is an NHS programme aimed at reducing unnecessary procedures, referrals and clinical variation across the health service. In ophthalmology, it is directly relevant to glaucoma referral refinement. The NHS wants fewer inappropriate referrals from primary eye care. It wants community optometrists referring with data that secondary care can act on directly.

The 7CR aligns with that goal. An independent practice using IOPcc measurement is doing what the NHS is asking primary eye care to do. That is not just good for the health service. It is good for the relationship between your practice and your local hospital eye service — and for the patient sitting in front of you who needs a referral decision they can trust.

Independent practices with strong referral relationships with local secondary care build reputations that multiples struggle to match. The clinical credibility compounds. Patients notice when their optician's referrals lead to treatment rather than discharge.

Who it is most useful for

The 7CR is clinically relevant across a wider patient range than standard tonometry. It is specifically indicated for normal tension glaucoma suspects, primary open angle glaucoma patients, post-LASIK and refractive surgery patients, patients with Fuchs' dystrophy or corneal oedema, keratoconus patients, and anyone with biomechanically atypical corneas. That covers a significant proportion of a community practice's at-risk patient population.

For practices already invested in glaucoma monitoring — OCT, visual fields, disc imaging — the 7CR completes the picture with pressure data that secondary care will actually act on.
