Clamp Optometrists Ltd - Award Winning Practice

06/03/2026

A colleague once told us the secret to a great optical practice is simple: never stop being curious about the person sitting in front of you. Not their prescription. Them.

After decades in Cambridge, we've found that rings true. The clinical side matters enormously — investing in diagnostic technology, pursuing higher qualifications, staying current with research. But the practices that thrive long-term share something less tangible. They treat every appointment as a conversation, not a transaction.

A few things we've learned along the way:

Spend longer than you think you need to. Rushed consultations erode trust faster than anything else. When someone feels genuinely heard, they come back. And they tell people.

Invest in your team's growth before you invest in your shopfit. The best equipment in the world can't compensate for a team that doesn't care. Give people room to develop clinical skills, encourage them to specialise, and watch what happens.

Curate, don't stock. Whether it's frames or contact lens options, having a carefully chosen range tells your patients you've done the thinking for them. Nobody wants to wade through hundreds of identical options.

Say what you don't know. Patients respect honesty far more than bluffing. Refer when you should. Collaborate with other clinicians openly.

And finally — don't be afraid to have a personality. Eye care is serious. The experience of getting it doesn't have to be. A bit of warmth, a bit of humour, a genuinely enjoyable visit — these things aren't unprofessional. They're memorable.

What's one thing you wish more optical practices did differently?

Every week, we review OCT scans where the segmentation lines have quietly drifted off course.

Those automated boundary markers the software places between retinal layers look convincing on screen. But epiretinal membranes, vitreomacular traction, even dense cataracts can throw the algorithms off. The machine dutifully measures the retinal nerve fibre layer or ganglion cell complex, produces a colour-coded map, and flags it red. Alarm bells ring.

Except sometimes that red zone is an artefact — the software misidentifying where one layer ends and another begins.

We've made it standard practice to manually verify segmentation on every scan showing an unexpected change. It takes an extra minute or two per patient. That minute has, on more than a few occasions, been the difference between an unnecessary hospital referral and a calm, accurate conversation about what's actually happening.

The flip side is what keeps clinicians up at night. A scan can appear reassuringly green while subtle thinning hides behind a segmentation error that's artificially inflating thickness values. Green doesn't always mean safe.

OCT technology gives us extraordinary data. But the real skill isn't in pressing the button. It's in the interpretation — knowing when to trust the numbers and when to override them. The clinical judgement applied to that data is what turns it into something genuinely useful.

How much time does your eye care provider spend actually looking at your scan with you?

What a weekend. 100% Optical at ExCeL London never disappoints — though our feet might disagree 🦶

Three days of geeking out over the latest diagnostic tech, discovering frame designers we'd never heard of, swapping clinical war stories over questionable coffee, and laughing far too much with the people who make this profession such a joy.

The new kit was exciting (and there was plenty to get the pulse racing). But honestly? It's the people. Catching up with friends from across the country, comparing notes on tricky cases, celebrating each other's wins. There's a genuine warmth in this community that's hard to explain to anyone outside it.

We came away with fresh ideas, new connections, and the kind of energy you just can't get from a webinar. Also a suspicious number of tote bags 👀

Already counting down to next year. Who else was there?

A 14-year-old came in last month wearing monthly contact lenses fitted elsewhere. On the slit lamp, everything looked fine — good centration, movement on blink, no redness. But their vision kept dropping off by the end of each school day, and screen work was triggering headaches.

We ran full corneal topography and mapped the sagittal height profile. The cornea was slightly more prolate than average, with asymmetric toricity that a standard flat-and-steep K reading completely missed. The lens was vaulting centrally and bearing down at the periphery — creating just enough decentration under fatigue conditions to degrade the optics.

Swapped to a design selected using the full topographic dataset. Different base curve, different edge profile. Symptoms resolved within a week.

This is a pattern we see more often than you'd expect. Contact lens fitting has traditionally followed a reliable but limited pathway: refraction, keratometry, pick a lens from a fitting guide, check the fit, send the patient off. For a lot of wearers, that approach works perfectly well. But "well enough" leaves a significant minority with subclinical discomfort, variable vision, or reduced wearing time that they just assume is what contacts feel like.

The diagnostic tools to do better already exist. Anterior segment OCT can measure tear film thickness under the lens. Topography-guided fitting software can match lens geometry to actual corneal shape rather than a two-point approximation. Aberrometry can quantify optical performance on eye rather than relying purely on "is that better or worse."

We've found that spending an extra ten minutes on the front end — running the topography, assessing the tear film properly, understanding the patient's visual demands across their whole day — cuts follow-up visits dramatically. The fitting succeeds first time more often. Compliance improves because the lenses are genuinely comfortable, not merely tolerable.

For younger patients especially, where we're often fitting ortho-K or specialist myopia control lenses, this precision isn't optional. A 0.2mm error in sagittal depth on an overnight ortho-K lens changes the entire treatment zone centration. That directly affects the myopic defocus profile and, ultimately, whether the treatment delivers the results it should.

What would happen if every contact lens fitting started with the same diagnostic rigour we apply to detecting disease?

Events like this remind you why you got into optics in the first place. The new kit is exciting (and there was plenty to get the pulse racing). But honestly? It's the people.

A -8.00 prescription in a standard 1.5 index lens is thick. Properly thick. The kind of thick that makes frames feel heavy, edges look like bottle bottoms, and wearers quietly dread putting their glasses on.

So let's talk about what actually makes a difference when you're working with high myopia.

Refractive index is the starting point. The higher the index, the thinner the lens. A 1.5 index at -8.00 will give you an edge thickness that's dramatically different from a 1.74 index. We're talking millimetres that genuinely change how a pair of glasses looks and feels on your face. For prescriptions above -6.00, we'd almost always recommend 1.67 as a minimum, with 1.74 being the go-to for anyone who wants the slimmest possible result.

But here's the thing most people don't consider: higher index lenses are denser. A 1.74 lens is thinner, yes, but the material itself is heavier per cubic centimetre than a 1.5. The weight saving comes from removing volume, not from the material being lighter. In moderate prescriptions the difference is negligible. In high myopia, choosing the right frame size matters just as much as choosing the right index. A smaller, well-fitted frame reduces the lens diameter, which cuts both thickness AND weight far more effectively than index alone.

Then there's coatings. Higher index materials reflect more light. A 1.74 lens without a decent anti-reflection coating can look like a pair of mirrors. That's not a style choice anyone's making on purpose. A premium multi-layer AR coating cuts those reflections right down and improves clarity for the wearer too. Add a hydrophobic top layer and you've got lenses that stay cleaner longer and resist smudging.

For anyone with high myopia, the combination of high index material, a carefully chosen frame size, and proper coatings isn't a luxury. It's the difference between glasses you tolerate and glasses you actually enjoy wearing.

What index are your current lenses? Worth checking next time you're in.

Bevel eyewear starts with a simple idea: strip away everything unnecessary and let the craftsmanship speak.

Every frame is milled from a single block of material, whether that's Japanese titanium or hand-finished acetate. No welding. No soldering. Just clean, precise engineering.

The hinges are custom-designed for each frame style. The temples are shaped to distribute weight evenly. Even the screws are proprietary.

We carry Bevel because our clients notice these things. They pick up a frame and feel the difference immediately. The balance. The finish. The way it sits without constant adjusting.

When the optics and the frame are both made without compromise, you end up with something exceptional.
