Hello,
I am creating an app using App Designer and I would like to be able to browse several DICOM images at the same time. I need the first one to show in the first place and then to be able to change to the next one by pressing a button.
Right now I have the code for browsing and showing only one DICOM file as it follows:
[fn, pn] = uigetfile({'*.dcm'},'select dicom file');
complete = strcat(pn,fn);
I = dicomread(complete);
imshow(I,[],'Parent',app.UIAxes);
I also have a button called "Next image", but I'm begginer and quite lost on how to achive what I need,

I suggest that you use MultiSelect with uigetfile. Test the results to see if isnumeric(fn) and if so then the user cancel. Then fn=cellstr(fn); to make it easier to handle the case that the user selected exactly one file.
Now keep an app property which is the index of the current image. You could use a slider or a drop box to have the user select an image. In the callback, get the new value, make sure that it is in range, set the mentioned app property to the new index, and use the index to pull out the filename and display it.
Also please use fullfile() to build file names. uigetfile does not always put a directory separator at the end of the path it returns.

Is load_image_at_index a method of your class ?
You do not show how you are calling dicomread() after this revision
