In the event of a power outage, the smartphone flashlight may be used as a light source for the slit lamp. First, the outer casing of the slit lamp tower is removed [Figure 1], followed by the removal of the bulb and the condensing lens [Figure 2]. The phone flashlight is turned on, centered over the slit apparatus and taped in place [Figure 3] and [Figure 4]. This produces a bright slit beam of adjustable height/width comparable to that of the original bulb. The cobalt blue filter can be applied as needed. This low-cost setup may be useful in an emergency when the power outage occurs unexpectedly when there is a bulb malfunction without an adequate replacement, or in areas of low resources during electricity rationing.
