How Can an Optician Send Sight Test Reminders at Each Patient's Own Recall Interval?

Opticians' eye test recalls go out late or on one fixed interval. We send reminders at each patient's recorded interval and track who has not booked.

Quick answer — TL;DR

Recalls go wrong because the interval each optometrist records is not always what drives the reminder, and nobody follows up the patients who ignore it. We build a recall process that reads the interval recorded at each test, sends reminders on that schedule by the patient's preferred channel, follows up in stages, and gives the practice a list of overdue patients to call.

Recall is the practice's heartbeat

For an independent optician, recall is how most sight tests get booked. The optometrist records a recall interval at each test, perhaps one year for a child or an older patient, two years for most adults, a different interval where there is a specific reason. In theory, the practice management system sends a reminder at the right time. In practice, the recall run is a monthly job someone does when they have time, letters go out in a batch, and patients who ignore them are not chased.

Then a patient comes in with a problem and mentions they had not been reminded, and the record shows they are eighteen months overdue.

Why recalls slip

  • The recall run is a manual batch rather than something that happens continuously.
  • Some tests record a different interval from the default, and the batch uses the default.
  • Letters are still the main channel, which is slow and costly, and many patients prefer text.
  • There is no second or third reminder, so one ignored letter ends the process.
  • Patients who moved or changed number are never cleaned out, so the list gets noisier.

Contact lens aftercare usually runs on a separate schedule that makes the picture even more confusing, with patients receiving two different reminders a few weeks apart.

What late recalls cost

ProblemEffect
Reminders sent late or not at allTests happen later than the optometrist intended
One reminder onlyPatients who meant to book forget
Letters as defaultPostage costs and slow response
Stale contact detailsWasted reminders and a misleading recall list
Separate CL and sight test remindersConfused patients and two visits instead of one

Missed recalls mean an emptier test room diary and patients whose care is less regular than the optometrist recommended. They also leave the door open for a chain practice's reminder to arrive first.

How we build interval-based recall

  1. We read each patient's last test date and the recall interval recorded by the optometrist from your practice management system, through its API or a scheduled export.
  2. Reminders are scheduled from that interval, not a default, and sent continuously rather than in a monthly batch.
  3. Each patient is contacted on their preferred channel, text, email or letter, using wording you approve, with a link to book online where you offer it.
  4. If there is no booking, a second reminder follows, then the patient appears on a call list for reception.
  5. Where a patient also wears contact lenses, the sight test and aftercare reminders can be combined into one message if your practice prefers.
  6. Bounced emails, failed texts and returned letters mark the contact detail for checking at the next visit.
  7. A monthly report shows patients due, reminded, booked and overdue, by optometrist if useful.

We do not set recall intervals. They come from the optometrist's clinical judgement, recorded at the test, and your practice's own policies on eligibility for NHS tests where relevant.

The practice with recall running properly

Reminders go out at the right time for each patient, without anyone running a batch. Patients who ignore the first message get a nudge, and then a call. The diary fills more predictably. And the recall list stays accurate because bad contact details are caught and fixed.

Practices that run domiciliary or care home visits can include those patients too, with reminders directed to the care home or next of kin as your records specify.

Could this be your practice?

  • Recall reminders go out in a monthly batch.
  • Most reminders are still sent by post.
  • Patients receive only one reminder.
  • You have patients well overdue who say they were never reminded.
  • Contact lens and sight test reminders arrive separately.

FAQ

Frequently asked questions

Ask about your project

Does this work with our practice management system?

It needs test dates, recall intervals and contact details, which optical practice systems generally hold. We check how yours exposes them, by API or export.

Can we keep sending letters to some patients?

Yes. Patients who prefer letters, or have no mobile or email, still receive them.

Will it book appointments automatically?

It sends a link to your online booking if you have one. Otherwise, it prompts the patient to call and gives reception a list.

What about NHS eligibility for sight tests?

Eligibility and intervals for NHS tests follow the rules that apply in your nation and your optometrist's judgement. The system uses what is recorded, it does not decide.
