At a glance
TL;DR — What is Ophthalmology Accounting?
Ophthalmology practice accounting is the financial management discipline for eye care practices: separating medical, surgical, optical, and cosmetic revenue streams, tracking ASC cost allocations, and reconciling implant costs per case. Ophthalmologist-owners use it when they need clear margins across a practice that earns money in several different ways. Sorso is an accounting and bookkeeping firm that does this for ophthalmology practices across the US. Accounting starts at $2,000 a month, month-to-month after onboarding, with a 45-day money-back guarantee; tax preparation and filing stay with your CPA.
Industry Context
How Ophthalmology Practices Actually Run Their Books
Ophthalmology practices operate as multiple businesses under one roof: clinical ophthalmology (office visits, examinations, injections), surgical operations (cataract, retina, oculoplastic), optical shop retail (frames, lenses, contacts), and often an ambulatory surgery center (ASC) that may be partially owned by the ophthalmologists. Each of these has different economics, different accounting treatment, and different tax implications. Most generic accounting setups treat the combined entity as one business and miss nearly every lever that actually drives profitability.
Ophthalmologist-owners need true segment financials. The clinical practice runs on professional fee collections; for ophthalmology practices as a whole, FTI Consulting's 2024 review of the sector estimates operating margins at 30 to 45 percent of net revenue. The optical shop runs on product margins with a different cost structure: in the Management & Business Academy's Key Metrics report on independent optometry practices, eyewear gross margin had a 61 percent median and soft contact lenses 46 percent. An ASC needs its own financial statements and often its own ownership structure with ophthalmologist investor-partners. In Pennsylvania, which collects cost data from its ASCs, the ASC operating margin was 29.5 percent in 2024, up from 22.3 to 25.6 percent in 2015 through 2023, according to MedPAC. Without clean segment reporting, owners cannot make informed decisions about capital allocation across these businesses.

What We Often Find
Common Accounting Mistakes in Ophthalmology Practices
These are common mistakes worth checking for in the books of a ophthalmology practice.
01
Lumping optical shop revenue with clinical revenue
Frames, lenses, and contacts are retail product revenue with very different gross margins and different staffing economics than clinical visits. Mixing them creates a blended margin that tells owners nothing about either business.
02
Not separating ASC revenue from practice revenue
When the ASC is owned by the practice or by a related entity, revenue flows need to be tracked separately. Most practices do this poorly, creating tax and regulatory risk in addition to obscuring ASC profitability.
03
Treating premium IOL upcharges as standard revenue
The non-covered portion of premium IOLs (multifocal, toric, EDOF) is cash collected directly from the patient and flows outside Medicare reimbursement. It should be tracked separately because it has different tax treatment and different collection dynamics.
04
Booking anti-VEGF drug revenue gross without tracking acquisition cost
Eylea, Lucentis, and Avastin flow through buy-and-bill at high dollar amounts with variable margins per drug and per payer. Tracking these as a single drug line obscures per-drug contribution margin and drug mix optimization opportunities.
05
Not amortizing capital equipment against actual case volume
A femtosecond laser depreciated on a straight-line basis ignores actual case volume. True cost-per-case analysis requires allocating equipment cost against the cases where it was used.
The Numbers That Matter
Key Accounting Metrics for Ophthalmology Practices
Revenue by Segment
- Clinical, surgical, optical, and ASC revenue as separate line items on segment reporting.
Premium IOL Conversion Rate
What we look for: Above the U.S. average of about 21 percent (Market Scope data, 2025)
- Premium lens implants divided by total cataract surgeries.
Anti-VEGF Revenue per Injection
- Net revenue after drug cost per injection, by drug type.
Optical Capture Rate
What we look for: 50 percent or higher
- Percentage of refractive exam patients who purchase frames or contacts in-house.
Surgical Case Volume per Surgeon
- Surgical cases per surgeon per month, by case type.
Practice Overhead Ratio
What we look for: 55 to 65 percent
- Practice operating expenses divided by practice collections (excluding ASC).
Software & Vendors
EHR, PM, and Vendor Reality for Ophthalmology Practices
Ophthalmology practices commonly run on EMA/Modernizing Medicine, Nextech, NextGen, Epic, or RevolutionEHR. Modernizing Medicine and Nextech are the most common independent platforms; Epic appears in hospital-affiliated practices; RevolutionEHR is popular in optical-focused practices. With three separate revenue sources (clinical, ASC, and optical) running on different data systems, reconciliation is harder here than in most specialties.
Drug and supply vendors heavily affect economics. Anti-VEGF manufacturers (Regeneron for Eylea, Genentech for Lucentis and Avastin, Novartis for Beovu) have varying economics that affect retina practice margins. IOL manufacturers (Alcon, Johnson & Johnson Vision, Bausch + Lomb) have preferred programs and volume discounts. Equipment vendors (Zeiss, Alcon, Topcon, Heidelberg, Lumenis) often have multi-year service contracts and consumable costs that need to be tracked separately from the capital purchase.

Results
Results in this example
| Metric | In this example |
|---|---|
| ASC reallocation | Correcting shared-cost allocation added several hundred thousand dollars to reported practice profit |
| Premium IOL margin | Margin roughly doubled through pricing and implant cost negotiation, adding six figures annually |
| Optical shop improvement | Margin moved into the high 20s through vendor consolidation, adding roughly $90K annually |
Illustrative Scenario
What This Looks Like In Practice
A multi-surgeon ophthalmology practice with ASC ownership, an optical shop, and employed optometrists, combined revenue in the $8M–$10M range. Owner-surgeon take-home was below expectations. Nobody could clearly explain the financial relationship between the practice, the ASC, and the optical shop.
What the review found:
- •ASC cost allocation subsidizing practice overhead by several hundred thousand dollars a year, so the practice looked profitable only because the ASC was absorbing shared costs disproportionately
- •Premium IOL upgrades generating meaningful patient revenue but at a sub-25% margin, driven by untracked implant costs and under-priced upgrade fees
- •The optical shop running at a low-double-digit margin, with frame purchasing fragmented across multiple vendors
- •Anti-VEGF drug waste billing (JW modifier) not being submitted, leaving mid-five figures in unbilled drug waste per year
Representative results
Correcting shared-cost allocation added several hundred thousand dollars to reported practice profit
ASC reallocation
Margin roughly doubled through pricing and implant cost negotiation, adding six figures annually
Premium IOL margin
Margin moved into the high 20s through vendor consolidation, adding roughly $90K annually
Optical shop improvement
The takeaway
The lesson from this example: without clean separation between practice, ASC, and optical, shared costs quietly migrate to whichever entity the GL defaults to. One entity ends up looking healthy while another absorbs the difference.
Common Questions About Accounting for Ophthalmology Practices
How much does ophthalmology accounting cost?+
Accounting starts at $2,000 a month. Onboarding is a one-time $3,000 to $9,000, depending on how much cleanup the books need. After that the engagement is month-to-month, with a 45-day money-back guarantee.
Do you prepare our taxes?+
No. We are not a CPA firm, so tax preparation and filing stay with your CPA. We keep the books every month, reconcile practice, ASC and optical revenue, and give your CPA reconciled books at year end.
How is Sorso different from a ophthalmology CPA firm?+
A CPA firm's core work is tax and compliance. Ours is the monthly books and what they show: separate P&Ls for the practice, the ASC and the optical shop, and implant cost per case, with three to five specific actions each month. You can keep your CPA for taxes and use Sorso for the books.
Do you work with ophthalmology practices in my state?+
Yes. We work with ophthalmology practices across the US. The work runs on your accounting, billing and payroll systems, so where the practice is does not change it.
How do you handle ASC and practice financial integration?+
We set up clear cost allocation between your practice and ASC, track shared resources properly, and give you separate P&Ls for each entity. This is the single biggest source of financial confusion in ophthalmology.
Can you track optical shop inventory and margins?+
Yes. We track frame and lens inventory, per-sale margins, vendor costs, and shrinkage. You will know your actual profit per optical transaction and which product categories are making or losing money.
How do you handle the complexity of surgical revenue accounting?+
We break it down by procedure type (cataract, retina, glaucoma, refractive) and track implant costs, facility fees, and professional fees separately. You see the true margin on every surgical category.
What about Medicare-specific accounting challenges?+
Medicare is the main payer for many common eye procedures and accounts for about half of ophthalmology billings, according to FTI Consulting's 2024 sector review. We track Medicare reimbursement rates by procedure, monitor rate changes, and ensure your financial reporting accounts for the lower margins on Medicare patients.
Do you handle multi-entity structures?+
Yes. Many ophthalmology practices have separate entities for the practice, ASC, optical, and real estate. We handle the consolidated and individual entity reporting.
How do you track drug costs for buy-and-bill medications?+
We track purchase costs, administration billing, wastage, and net margin per injection. Anti-VEGF drugs alone can be a $500K+ line item — you need to know your actual margin.
