D-02 — NEW PATIENT VOLUME · EYE CARE GROUPS

New patient volume is short of plan — eye care

The exams happen. The purchase happens somewhere else.

DIFFERENTIAL — LIKELY CAUSES, MOST LIKELY FIRST

1. 01

   Walk-out at the exam-to-dispensary handoff

   The practice performs the clinical work, hands over a portable prescription, and loses the transaction to a retailer, a chain or the internet. Independents own the exam nationally and do not own the purchase — and the gap between those two facts is the entire economics of this vertical.

   Independent ODs hold a 53% share of primary eyecare patients but only a 42% share of revenue — the source states the cause outright: "because their capture rate of patients purchases of vision correction devices is much less than 100%." Independent ECPs' measured walk-out: about 30% for eyeglasses and about 38% for contact lenses. Of contact lens walk-outs, 46% go to internet retailers — more than double the 22% share internet held in 2007.

   Jobson Medical Information, quoted verbatim in MBA "Key Metrics," p.4. Walk-out rates and destinations: The Vision Council / VisionWatch, presented to the FTC by Steve Kodey, 2018-03-07 — read in the federal public record at ftc.gov. VisionWatch was discontinued in Q4 2021; these are 2017 figures and the direction matters more than the level.

   NOT THIS IF — Your eyewear Rxes per 100 complete exams sits above 88 (80th–89th percentile). At that level the handoff is working and the thin optical is a product-mix or pricing question instead.

2. 02

   Capture rate is not measured, so it cannot be managed

   The single defining metric of the vertical is absent from three-quarters of practices' reporting. Without it, an optical decline is invisible until it shows up in the annual P&L, by which point a year of Rxes has already left the building — which is why optical capture rate gets instrumented per location before any spend is added.

   Just 23% of practices ever track their eyewear sales capture rate — and that is measured inside a sample the publisher itself describes as running about 50% above the median US independent OD in revenue. The same passage names walk-out as representing "enormous revenue loss to independent eye doctors."

   MBA "Key Metrics," p.21 — n>1,900 US private optometric practices, 2015 edition. The 23% is a measurement-behaviour finding, not a dollar level, and is the most durable single fact in this vertical's harvest.

   NOT THIS IF — Capture is already on a monthly report, computed with a stated denominator, and broken out by doctor and by optician. Then the number exists and the problem is what it says, not that it is missing.

3. 03

   Second-pair and lens-value attach never happen

   One pair per purchasing patient at a mid-tier lens is the default outcome when nobody is responsible for the second conversation. The revenue is not lost to a competitor — it is never created, and it carries the practice's best margin.

   A median of 10% of patients who purchase eyewear buy more than a single pair during an exam visit; 75th percentile 15%, 85th 20%, 95th 33%. The publisher sizes the opportunity itself: moving the multiple-pair ratio from 10% to 15% is likely a 1–2% increase in practice revenue, and notes second-pair discounts average just 20%, "which consultants claim is too low to create an immediate call-to-action." On the lens side, most upgrades increase sales per eyewear Rx by 20% or more, and eyewear gross margin runs 61% (2.6× markup) at the median against 75% (4.0×) in the top decile — achieved "primarily by selling higher value products rather than by taking significantly higher mark-ups."

   MBA "Key Metrics," pp.22–24 (n>1,900). Median retail sale per pair $227; average gross profit per eyewear Rx $138. 2010–2012 dollar levels; the ratios and the margin mechanism are the durable findings.

   NOT THIS IF — Second-pair ratio is already at or above 15% — a level the publisher says is "within the reach of most practices" — and your eyewear gross margin is above 66% (70th–79th percentile).

4. 04

   The contact lens supply annuity leaks

   Contact lenses are the only genuinely recurring line in the practice, and it converts at the chair or not at all. Patients who leave with two months of lenses buy the remaining ten somewhere cheaper, and the modality mix is moving against annual-supply conversion.

   Median annual contact lens sales per contact lens exam: $152, against an average soft lens box retail of $42 — equivalent to 3.6 boxes, well under an annual supply. Annual-supply purchase rate: 25% of two-week soft lens patients, 60% of monthly patients, and "few daily disposable wearers purchase an annual supply" — while daily disposables now lead prescribing at 43%–59% across three independent datasets. Contact lens materials are 16% of gross revenue at the median against 32% in the top decile; a median of 30% of active patients wear contact lenses.

   MBA "Key Metrics," pp.30–31, 35, citing its own Contact Lens Management Survey (December 2011). Modality mix: Contact Lens Spectrum, "Contact Lenses 2025," triangulating its Reader Profile Survey, ABB Optical Group and NIQ — the publisher declines to resolve the 16-point spread across the three datasets, so report the range and never a midpoint.

   NOT THIS IF — Contact lens materials already exceed 19% of gross revenue (70th–79th percentile) and annual-supply conversion is above 60%. The primary flags a contact lens sales ratio below 12% as symptomatic — including of a contact lens purchase capture rate under 80%.

5. 05

   Payer mix is suppressing capture, particularly among self-pay seniors

   Capture is not a constant across the patient base. A patient with a materials benefit converts at a materially higher rate than the same patient paying cash — and the gap widens dramatically with age. A practice with an older, self-pay-heavy panel will read low capture as a selling problem when a large part of it is mix.

   2024 optical capture rate: 60.1% overall, 66.0% for patients with a vision plan, 54.3% for self-pay. By age, the self-pay cliff is severe: at 65+, capture is 70.6% with a vision plan against 37.3% self-pay. Under 18 is the only band where self-pay outperforms (51.4% against 48.0%).

   GPN Technologies, analysis of its own database — 1,000 US optometric practices and over 7 million recorded eye exams and eyewear purchases in 2024, published at GPN VISIONS. Transaction-derived (point of sale), not survey recall. Population limit: GPN EDGEPro subscribers, i.e. practices that bought analytics software, so upward-biased on measurement discipline.

   NOT THIS IF — Your capture rate is flat across payer segments and age bands. Then mix is not the explanation and the leak is in the handoff or the product offer.

HOW TO TELL THEM APART

How to tell these apart in your own numbers

Each of these is a measurement you can run yourself, without us.

WHAT RESOLVES EACH

What resolves this, and how you will know it resolved

Walk-out at the exam-to-dispensary handoff	Rx 03 · patient conversion →	The handoff is a process with a start, an owner and a measurable outcome — the doctor's transition to the optician, the frame-selection start time, and whether the patient is ever handed to a named person at all. What does not work: buying more exams into a dispensary losing 30% of them. Every additional exam raises cost and reproduces the leak.
Capture rate is not measured, so it cannot be managed	Rx 04 · marketing attribution →	Capture on a monthly one-page readout, with the denominator printed next to the number, broken out by doctor and by optician. Three-quarters of the profession does not have this. It is the cheapest credibility a practice can buy with itself.
Second-pair and lens-value attach never happen	Rx 02 · medical practice websites →	Value attach is a presentation problem before it is a sales problem — what is on the board, how the second pair is framed, and whether the practice reads as a place that sells good eyewear. Two constraints from the primary: gross margin gains come from selling higher-value product rather than raising markups, and a dispensary under 500 square feet risks being perceived as offering a limited frame selection. That last one is a build decision, not a marketing one, and we would say so.
The contact lens supply annuity leaks	Rx 03 · patient conversion →	Annual supply converts at the chair, in the exam, before the patient stands up — box count is the friction, so the offer has to be built around it. This is the only recurring revenue line in the practice; it should be the most instrumented one and usually is the least.
Payer mix is suppressing capture, particularly among self-pay seniors	Rx 04 · marketing attribution →	Segment the capture readout by payer and by age before drawing any conclusion about the optical team. What does not work: coaching a team against a blended number that a demographic shift is driving.

HOW THIS DIFFERS BY SCALE

How this differs by scale

Single site	Capture is a person-level number here — one doctor's transition habit and one or two opticians' selling habits explain nearly all of it. Measure by individual from the first week; a blended practice number in a two-optician office is an average of two very different things.
Group	Capture does not vary significantly by practice size, so a site's capture rate is a clean read on that site's process rather than on its market. That makes it the single best cross-site diagnostic in the vertical — and it is why the group that installs the measurement usually finds a 20-point spread it did not know it had.
Platform	At platform scale the leak compounds: independents nationally hold 53% of patients and 42% of revenue, so a platform assembled from independents inherits the gap at every location it buys. The contact lens line deserves separate treatment — it is the only annuity in the model, it converts at the chair, and the modality mix is moving against it as daily disposables take 43%–59% of prescribing.
