Thermal paper and a pen
The pre-test room is busy. The optical assistant runs the autorefractor, the non-contact tonometer and the lensmeter on the patient's current glasses. Each instrument prints a small slip of thermal paper. The slips are clipped to the patient's card or placed on the desk, and either the assistant or the optometrist types the numbers into the practice system.
Most of the time it is right. Occasionally a digit is transposed, a slip goes with the wrong patient, or the faded paper is unreadable when someone looks back at it later.
Why readings are still typed by hand
Many instruments can send their readings electronically, through a serial or USB connection, a network link or a data file, but the connection has never been set up. Practice systems vary in what they can receive directly. Older instruments may only print. And nobody at the practice has the time to work out which devices can talk to what.
So the default is paper and retyping, because it works everywhere.
What retyping costs
| Issue | Effect |
|---|---|
| Retyping each reading | Time in every pre-test |
| Transcription errors | Wrong numbers in the record |
| Slips with the wrong patient | Readings attached to the wrong record |
| Faded thermal paper | Evidence unreadable later |
| Readings on separate slips | Optometrist gathers them before starting |
The optometrist should be spending the test on the patient, not on checking whether a number was typed correctly. Anything that reduces transcription improves both the test and the record.
How we connect the instruments
- We survey the instruments in each pre-test and test room, including make, model and the data outputs each supports.
- The patient is selected on the pre-test PC or tablet at the start, from the day's diary in your practice system.
- Instruments that can send data are connected, directly or through a small bridge device, and their readings are captured against the selected patient.
- Readings are written into the patient record in your practice system where it accepts them, or shown in a one-page summary the optometrist can view and copy in one step.
- Instruments that cannot send data are listed, with a quick-entry screen that at least keeps their readings in the same place.
- Every captured reading keeps its original timestamp and device, so it can be checked later.
Where your practice system or instrument supplier already offers an integration for your equipment, we will tell you and help set it up instead of building something new.
What the pre-test looks like afterwards
The assistant selects the patient, runs the instruments, and the readings are already there when the optometrist opens the record. No slips, no retyping, no faded paper. The optometrist starts the test with a complete, legible set of readings. And every reading carries its source, so there is no doubt later about where a number came from.
Replacing an instrument becomes a question of whether the new one can send its data, which is worth asking before you buy.
We roll the connections out one room at a time, starting with the instrument that generates the most retyping. Staff try it on a normal day, we fix anything awkward about patient selection or timing, and only then move to the next device. Paper slips stay available as a fallback until everyone is comfortable.
Does this sound like your pre-test room?
- Pre-test instruments print thermal slips.
- Readings are typed into the practice system by hand.
- A slip has ended up with the wrong patient.
- Old slips are faded and hard to read.
- Nobody knows which instruments could send data electronically.
