Workflow

Documentation and examples for a typical workflow.

Add patients

Simply start by clicking on Add person in the sidebar. A column with some input fields and buttons will appear. Here you need to fill in some basic information about the patient. After filling in all the input fields and choosing a gender option, you can press on the Save information button. The app will notify you if you make a mistake (by accident) and will indicate what field is not correct.

Search patients

If you want to retrieve a person's data, you have to click on the Search person button at the top of the sidebar. Start by typing in (a part) of their name. Simply press enter on your keyboard to search. If you entered the exact name of a patient you will directly see their info, else some suggestions are listed.

Measure AxL values

To see the AxL values on the growth chart, you will have to type the values in the check up fields. You can specify only the right eye value, only the left eye value or both eye values. The custom date field is optional. Hereby you can save previous check ups. If left blank, the app will assign the current date to the AxL values. Then simply press Add check up and the chart is updated. If you wish to only see the line of one eye at a time, you can click on ▬ left eye or ▬ right eye buttons right above the chart, as displayed in the picture below.

Edit information

You can edit a person's information by clicking on the Edit information button below the patient's info card. When completed, don't forget to save the changes. Moreover you can delete previous check up values by clicking on the red cross ⛒ on the right side of the AxL values. Be aware that you can't undo any edit/delete operation.

Q&A

Is the application 100% free?

Yes. It is not a trial version and there is no paid version. We also don't sell or collect any user data. If you like the app, a donation is much appreciated! If not, please leave a review on the Microsoft Store or send an email explaining why.

What is the difference between the Microsoft Store version and the portable version?

When you download the application from the Microsoft Store, you can only use the app on the device you installed it from the store. All the data is saved in your local Documents folder. In theory you could copy the saved data from this folder and use this data on another computer where Myopia chart is installed. But it's much easier to use the portable version in this case. The portable version saves data in the same folder as the program is located. This way you just have to save the folder on a USB drive and you can use Myopia chart hassle free on any Windows computer without the need to install an extra copy of Myopia chart.

Can I delete all the information?

Yes, but at your own risk, because the app does not save a back-up. To delete all the information, you have to delete the person.hive file. For the Microsoft Store version, this file is located in Documents/Myopia chart data folder. For the portable version, this file is located in the same folder as the executable, namely Myopia chart.
