The move to touch screen control continues and the new AFC-330 is the latest instrument to exploit this (Figure 1). The 21cm touch screen makes patient data input a quick and simple operation and then the choice of image to be taken (anterior, disc-centred, usual retinal, stereo, mosaic) just as easy. The screen is large enough to allow for useful review. For example, the images taken from one patient can be displayed in one view to allow easy deletion of those not satisfactory (Figure 2), while the images of each disc may be displayed side by side for an initial assessment of any asymmetry (Figure 3). This is before the process of saving on computer for more thorough analysis as in the usual way. I like this as it allows for a very quick assessment while the patient is still in position.
