Optical capture rate is the single most important number in an independent eyecare practice. Every comprehensive exam that ends with a prescription is a fork in the road: the patient either buys eyewear from your optical or walks out with a released Rx and spends that money somewhere else. Capture rate measures which way they went, and because a few points of capture translate into real annual revenue, it is the metric owners and buying groups obsess over. This dashboard tracks exactly how many exams convert and what walks out the door.
What this dashboard answers
The Capture Overview answers the questions an owner or optical manager asks every week: of the exams that issued an Rx, what share did we capture in-house? How many prescriptions walked out unfilled, and how much revenue did the captured exams produce? A donut splits every exam into Captured, Walk-Out, or No-Rx, a bar ranks capture rate by location, and a monthly trend shows whether conversion is improving or slipping. The Conversion Drivers page then breaks the same rate down by provider (OD) and by insurance type, and shows captured exams by eyewear category — so you can see whether the leak is a doctor who doesn't hand off, a plan whose patients walk, or a category you're not selling.
The metrics that matter
Capture rate is a ratio of two counts — captured exams over Rx-issued exams — so it is computed as a sum over a sum, never as an average of per-row percentages. Around it sit the absolute counts that make it real: completed exams with an Rx, eyewear orders captured, the walk-out count, and second-pair attach. Captured optical revenue ties capture back to dollars, because a high capture rate on thin sales is a different problem than a low rate on rich ones.
Why the data is trapped across the systems
Capture rate is the textbook example of a metric that no single system can produce. The numerator — captured eyewear orders — lives in the optical POS (Edge by GPN) and the dispensing tables of Eyefinity/OfficeMate. The denominator — exams that issued an Rx — lives in the EHR (RevolutionEHR, Crystal PM, Compulink). To get a real capture rate you have to match each exam encounter to whether a sale followed, by patient and date, across two systems that were never designed to join. Most practices end up doing it in a spreadsheet once a quarter, which is why the number is so often guessed at rather than managed.
How to read it
Start with the overall rate, then read it by location and provider to find where the leak concentrates. A provider with strong clinical volume but weak capture usually points to a hand-off problem at the exam-to-optical transition, not a pricing problem. Walk-out count is the dollars-on-the-floor number; second-pair attach is the upside. The sample here uses entirely synthetic exam and dispensing data, so you can explore the finished report with no patient information involved.
Metrics it tracks
| Metric | What it means |
|---|---|
| Optical Capture Rate | Eyewear orders captured divided by completed exams that issued an Rx — the headline exam-to-eyewear conversion rate (a SUM-over-SUM ratio). |
| Completed Exams (Rx Issued) | Count of exams where an eyeglass or contact-lens prescription was issued. |
| Eyewear Orders Captured | Count of exams that converted to at least one in-house eyewear or contact dispensing order. |
| Walk-Out (Rx Released) Count | Count of exams that issued an Rx but were not captured in-house — the released prescriptions that left the building. |
| Captured Optical Revenue | Frames, lenses, and contacts dollars across captured exams. |
| Second-Pair Attach Count | Count of captured exams that added a second complete pair or sunwear. |
Used by: Owner-optometrists (ODs) and optical managers
Frequently asked questions
What is a good optical capture rate for an optometry practice?
Independent practices commonly target a capture rate well above half of Rx-issued exams, and buying groups publish benchmarks in that range. The exact target depends on your payer mix and whether you fit a lot of contact lenses, but the point of tracking it is direction and spread: which providers, plans, and locations capture better, and where prescriptions are walking out unfilled.
Why can't my EHR or POS show capture rate on its own?
Because the two halves of the metric live in different systems. The EHR knows which exams issued an Rx; the optical POS knows which patients bought eyewear. Capture rate only exists once you join those records by patient and date — which is exactly what this template does so the number stops being a quarterly spreadsheet guess.
What is a walk-out, and why does it matter?
A walk-out is an exam that issued a prescription but resulted in no in-house eyewear sale — the patient took the released Rx elsewhere. Each one is captured clinical work that produced no optical revenue, so the walk-out count is the clearest dollars-left-on-the-floor figure in the practice.
