The quiet leak in every practice
Do the math on your own numbers. If you saw 3,000 patients last year and 60 percent came back on their own this year, that is 1,200 exams sitting in your records waiting for a nudge. At a conservative revenue per exam, an average recall program is not a marketing nicety. It is one of the largest revenue lines in the practice, and in most offices it is staffed by whoever has a free hour at the front desk, which means it is staffed by no one.
The fix is not effort. It is a sequence that runs on its own, with self-booking so a returning patient never has to call.
The sequence
A recall is not one message. It is a short series, each one small and polite, spread over weeks. This is the cadence we see work:
- 11 months after the exam: the first text. Texts get read within minutes; start there. Short, personal, with a booking link.
- A few days later: the email. More room to remind them what an annual exam covers, especially prescription expiration for contact lens wearers.
- Two weeks later: the second text. Different angle, same link. This one catches everyone who meant to book and got distracted, which is most people.
- The stragglers list. Whoever has not responded after the sequence goes on a short list your front desk can call in slow moments. You will find the list is a fraction of what they used to dial.
Messages that work
Three rules: sound like a person, mention something specific, make booking one tap.
- First text: "Hi Emma, it's been almost a year since your last eye exam at Lakeview. Dr. Mitchell has openings the week of the 14th. Book in two minutes: [link]"
- Contact lens angle: "Hi Marcus, your contact lens prescription expires next month. Grab an exam now so your reorders don't get interrupted: [link]"
- Second text: "Hi Emma, still holding a few times this month if you'd like to get your exam in. Takes two minutes to book: [link]"
Notice what is missing: "Dear valued patient," exclamation marks, and anything that reads like a billboard. The message should look like it came from your front desk on a good day.
Self-booking is the whole trick
Every message ends in a link where the patient picks a time and is done. If your recall ends with "call us to schedule," you have converted a 30-second task into a phone call both sides will postpone. Practices consistently see the majority of recall bookings happen outside office hours, which tells you exactly how many you were losing to voicemail.
The year-end multiplier
Layer one more sequence on top in the fall: benefits reminders. Vision benefits and FSA dollars expire in December, and most patients genuinely forget. A September or October message ("your vision benefits reset January 1, use them on an exam or new glasses before they're gone") fills the exact months practices usually scramble through. Same rules: specific, personal, one tap to book.
Measure one number
Recall rate: of the patients due for an exam each month, what percentage booked within 90 days? Get a baseline before you change anything, then watch it move. Practices running a real sequence with self-booking routinely double a phone-based recall rate. That single number tells you what the program is worth in revenue without any spreadsheet gymnastics.
Run it by hand, or don't
You can run this playbook manually: a monthly export of patients due, a texting tool, and discipline. It works until the person who runs it takes a vacation. Making it automatic, with every patient enrolled the day of their exam and the stragglers list generated for you, is what ODpal Grow is for. Grow also delivers recalls as free push notifications through your patient app first, saving the text messages for patients who need them. Either way, stop letting last year's exams walk to the chain down the street for want of a reminder.
