Several approaches to smartphone anterior segment photography that involve purchasing
an adapter to attach to the slit lamp have been described in the literature. Given
the frequent updates in sizes and shapes of smartphones, a practical stepwise approach
to capturing high-quality images without the need for an adapter is essential. First,
the illumination is set to be diffuse, using the slit-lamp integrated diffuser (Fig. 1A, 1B). The camera flash is turned off, and the slit lamp is brought into focus on the
anterior segment. The camera is then stabilized with support from the examiner's hand
over the top of the oculars while griping the phone between the index finger and palm
(Fig. 1C, 1D). The phone is then moved closer or farther away from the slit lamp in order to
find the appropriate focal distance. Lastly, the picture is taken with the examiner's
free hand by tapping the screen to take the picture (Video 1, available online).
