Imagine two refractive/lens clinics, each performing 1,000 private procedures a year. Same city. Same competitive landscape. Similar surgeons. Similar theatres.

Clinic A’s owners take home a healthy profit and feel in control.  

Clinic B’s owners look at their annual accounts and ask, “Where did it all go?”

The difference is almost never “busyness.” It is almost always how much profit they capture per patient.

Most ophthalmologists I meet don’t see this because:

• They only see net profit once a year on a set of accounts.  

• They rarely know their gross profit per case, so pricing is guesswork.  

Let’s fix that.

Step 1: Understand the two kinds of profit

Spending time and money on an Executive MBA isn’t necessary. You just need two simple definitions.

• Gross profit per case = Revenue per case − Direct costs per case.  

  • Take your revenue per case: what the patient (or insurer) pays you.  

  • Deduct your direct costs per case: lens and consumables, diagnostic tests, theatre time share, clinical staff time directly tied to that procedure, financing fees, etc.  

• Net profit = What is left after you’ve also paid everything else: rent, permanent staff, marketing, admin, IT, loan payments, etc.

Gross profit is the “oxygen” that pays for everything else and leaves something for you at the end. If you don’t know it by procedure type, you are flying blind on pricing. 

In elective eye surgery, you often only get one main shot per eye. You can’t rely on frequent repeat visits like you can in a coffee shop. That means your main growth lever is not “more visits,” but more profit per surgery.

Step 2: Value per patient is the real growth lever

Across industries, businesses grow mainly by:

1. Getting more customers  

2. Charging more per customer  

3. Getting them to buy more often

You already work hard on number 1 (marketing, referrals), and in refractive/ lens you’re limited on number 3. So the biggest unused lever in most clinics is number 2: how much profit you make per patient.

In other words: Value per patient = Gross profit per case × number of cases.

If two clinics both do 1,000 procedures, but one earns £1,000 gross profit per eye and the other earns £500, the first clinic has twice the fuel to pay great people, invest in technology, and still leave profit for the owners.

That difference does not come from working twice as hard. It comes from three controllable levers:

1. Case mix  

2. Pricing structure  

3. Conversion quality  

Lever 1: Case mix – what you actually sell

“Case mix” is simply which procedures your patients choose. For example, in a lens practice:

• Standard monofocal package at £X  

• Premium lens / enhanced package at £X + Y  

Clinic A might have 30 percent of patients choosing a premium package.  

Clinic B might have 60 percent choosing premium, with the same total volume.

If the incremental cost of a premium package is, say, £300 but the price difference is £1,500, then each premium case adds an extra £1,200 of gross profit. Shift 300 cases from standard to premium:

• 300 × £1,200 = £360,000 more gross profit per year  

No extra theatre time. No extra consults. Same number of eyes, very different economics.

Most clinics do not actively manage this. Premium is “offered” vaguely, or only if the surgeon remembers, or only when the patient asks. Premium uptake becomes random rather than designed.

Deliberately training your team to:

• Identify who is clinically suitable  

• Confidently recommend the premium option when it is in the patient’s best interest  

• Explain the value in plain language  

can change your case mix, and therefore your profit, without increasing volume.

Lever 2: Pricing structure – how you set your fees

Pricing feels emotional for many surgeons: “We are already expensive.” But the market does not care how you feel. It cares about the value patients perceive and your ability to explain it. 

A few principles:

1. Pricing hits profit harder than almost anything else.

If you run at 10 percent net margin and raise prices 20 percent (while case volume holds), you can roughly triple profit. Note that it’s no coincidence that I guide practice owners to triple their profits over 3 years. This is how we do it.

2. Start from gross profit per case, not from what competitors charge. 

•    List direct costs for each main package (monofocal, premium lens, laser).  

•    Decide on a target gross margin (many healthy elective businesses aim for 60 percent+).  

•    Set fees that give you that gross margin, then sanity-check against your market and your positioning.

3. Different patient segments can tolerate different prices. 

Some patients are extremely price sensitive. Others care more about convenience, surgeon reputation, technology, or extended support and are willing to pay more for those. They should not be charged the same. Finally, you do not need to “get it perfect” on day one. You can:

• Adjust fees modestly for new patients.  

• Watch conversion and satisfaction closely.  

• Keep nudging prices up until higher prices no longer increase your total profit.

Lever 3: Conversion quality – how well you turn demand into profitable cases

Most clinicians think they have a “lead problem” when they actually have a conversion and value-capture problem. 

Consider two clinics that both get 100 qualified refractive leads:

• Clinic A books 60 consults, 40 attend, 20 go to surgery.  

• Clinic B books 80 consults, 70 attend, 45 go to surgery.

At the same marketing spend, Clinic B more than doubles the surgeries. Now layer pricing and case mix on top:

• If Clinic B also has a higher premium uptake and better-priced packages, it might earn 3-4× the profit from the same number of inquiries.

Key conversion metrics to watch monthly:

• Lead to consult booked  

• Consult show rate  

• Consult to surgery conversion  

• Premium package uptake  

Training your team (or AI) on phone handling, pre-education, and clear recommendations often produces more profit than another round of advertising.

Why many clinics only see the problem once a year

When I ask, “What is your gross profit on a typical premium lens case?” most owners cannot tell me.

They get a yearly set of accounts showing:

• “Turnover”  

• “Cost of sales”  

• “Overheads”  

• “Net profit”

It is useful for the tax office, but almost useless for daily decision-making. What you actually need is a simple monthly scorecard by procedure type:

• Revenue per case (by package)  

• Direct costs per case (by package)  

• Gross profit per case and per month  

• Premium percentage  

• Basic conversion metrics

Once you have these, you can ask smart questions:

• “What if we increased premium uptake from 30 to 50 percent?”  

• “What if we added £300 to our premium package fee?”  

• “What if we improved consult-to-surgery conversion from 45 to 60 percent?”

Small, realistic improvements across those levers compound. In my world, we routinely see businesses transform with this sort of work, without doubling their volume. 

A simple starting plan for your clinic

If you run a private refractive or lens practice and this feels abstract, here is a concrete 90‑day plan:

1. Map your current economics (Month 1)  

•    Pick your top 2–3 procedure packages.  

•    For each, list: average fee, direct costs, gross profit per eye.  

•    Calculate your current premium mix and basic conversion funnel (lead → consult → surgery).

2. Pick one main lever to improve (Months 2–3) 

   Do not try to fix everything at once. For example:  

• Train your team to present premium options consistently, with scripts and visual aids.  

• Or tune your pricing on new patients by 5–10 percent and monitor.  

• Or focus on increasing consult show rate with better reminders and pre-education.

3. Review the numbers at least every month

• Track gross profit per case and per month, not just revenue.  

• Watch that patient experience stays high as you make changes.  

• If the numbers improve and satisfaction holds, keep going.

You will likely discover that “doing more cases” is not the real constraint. It is how much value you capture from the work you already do. When you understand and actively manage value per patient through case mix, pricing structure, and conversion quality, you give yourself permission to earn well, pay your team fairly, invest in technology, and still have profit left at the end of the year.

Same city. Same surgeons. Same number of eyes. Very different outcomes.
