No Front Desk of Your Own: How Optometrists Build Deliberate Careers From Per-Diem and Locum Shifts

For a long time, locum work carried a faint odor of improvisation — something an optometrist did while waiting for a real job to materialize. That framing no longer fits the market. Coverage gaps have become routine in practices of every size, and a cohort of optometrists has begun treating per-diem and locum assignments as the career itself rather than the interval between careers.

The shift is structural. Retail and corporate groups run lean schedules and need short-notice coverage when an associate resigns. Independent practices need someone during a maternity leave or a four-week recovery from surgery. Rural clinics, Indian Health Service facilities, VA sites, and correctional health programs need ODs for blocks of weeks at a time. Each of those needs is a shift, and enough shifts make a calendar.

The Difference Between Filling In and Building a Practice Portfolio

The distinction that separates a sustainable locum career from a stressful one is whether the optometrist is reacting to available shifts or assembling a known set of them. The first model is exhausting: every empty week feels like lost income, and every attractive assignment creates a scheduling conflict. The second model treats coverage relationships as a portfolio, with two or three anchor sites providing predictable recurring blocks and a rotating cast of secondary sites filling the remainder.

Anchor sites tend to be practices where the optometrist has become the default answer to a recurring problem — a Saturday rotation, a vacation relief pattern, a seasonal surge. They are worth cultivating deliberately, because reliability is the product being sold.

What the Day Rate Has to Cover

Day rates for optometric coverage commonly fall in the range of roughly $500 to $900 for a standard weekday, with higher figures attached to weekends, short-notice requests, rural locations, and assignments that include travel. Those numbers look impressive against a salaried equivalent until the missing pieces are added back in.

An independent contractor absorbs self-employment tax, malpractice premiums, licensure and continuing education costs, equipment such as a diagnostic set and handheld instruments, and the uncompensated hours spent on credentialing paperwork and scheduling. There is also the structural absence of paid time off: a two-week vacation costs both the expenses and the forgone shifts. Dividing a gross annual figure by 2,080 hours without adjusting for those factors produces a number that flatters the arrangement considerably.

The honest comparison is a rate sheet: gross receipts, minus business expenses, minus the value of benefits not received, divided by total hours worked including administrative time. Optometrists who run that calculation before committing to full-time locum work tend to make better decisions about which assignments are actually worth taking.

Credentialing Is the Slow Part Nobody Budgets For

Every new site requires paperwork, and the paperwork does not move at your pace. Expect primary source verification of your license, DEA registration where applicable, malpractice history, immunization records, and sometimes a background check and drug screen. Hospital-affiliated clinics and federal facilities add their own onboarding layers, and payer enrollment — Medicare, Medicaid, and vision plans — can take considerably longer than the clinical onboarding itself.

The practical lesson is to pursue credentialing ahead of need. An optometrist who is already credentialed at three health systems and enrolled with the major payers can accept an assignment on Monday that a colleague will not be able to start for six weeks.

The W-2 and 1099 Divide

Locum arrangements arrive under both classifications, and the difference is not cosmetic. Agency placements are frequently W-2, with the agency withholding taxes and sometimes providing malpractice coverage. Direct arrangements with a practice are often 1099, which shifts estimated quarterly taxes, expense tracking, and insurance onto the optometrist.

Either structure can work. What matters is that the classification matches the reality of the arrangement and that the contract identifies who carries malpractice coverage, at what limits, and whether tail coverage is included when an assignment ends.

Travel, Housing, and the Geography of Coverage

The further an assignment sits from a population center, the more the economics improve and the more the logistics intrude. Multi-week rural placements typically come with housing stipends or provided lodging and mileage or airfare, but the fine print matters: a stipend that assumes a shared apartment in a town with no short-term rentals is not really a stipend.

Optometrists who travel regularly tend to build repeat relationships with a small number of lodging options and keep a dedicated travel kit — a compact instrument set, a laptop, and copies of credentialing documents — so that packing is not a project each time.

Designing a Schedule Instead of Chasing One

A workable locum calendar usually blends three things: recurring anchor blocks booked months ahead, a buffer of two to four open days per month for short-notice requests at premium rates, and deliberate time off that is blocked before it can be filled.

Setting a minimum acceptable rate and holding to it is the discipline that makes the model durable. Practices that call on Friday for Monday coverage are not shopping on price; they are shopping on availability, and the rate should reflect that.

The Professional Cost: Continuity of Care

Flexibility is purchased with something real. Locum optometrists rarely follow a patient through a year of myopia progression control or a glaucoma suspect workup. They hand off. Some find that professionally satisfying — a steady stream of first encounters, no accumulated chart debt — and some find it hollow.

There is also a career-advancement dimension. Leadership roles, committee appointments, and mentorship relationships grow out of sustained presence at an organization. An optometrist who wants to move into clinical direction or practice ownership later will generally need at least one long-term institutional home, and it is worth planning for that rather than discovering the gap at the moment of applying.

Long-Term Earning Power and the Exit Ramp

Locum income scales with days worked, which means it flattens as soon as the calendar is full. There is no bonus structure, no equity, and no progressive responsibility. Optometrists who stay in the model for years often diversify — adding a consulting arrangement, a teleoptometry contract, or a part-time clinical director role at one of their anchor sites — to create income that is not tethered to hours in a lane.

Retirement planning deserves early attention as well. Without an employer match, the discipline of funding a solo 401(k) or SEP-IRA falls entirely on the individual, and the contributions are easy to defer during a lean quarter.

None of this argues against the model. It argues for running it deliberately. The optometrists who thrive on per-diem work are the ones who treat scheduling, credentialing, and pricing as seriously as they treat refraction — and who keep one eye on where the next phase of the career is headed.
