*6.2.2 Standard patient evaluation of eye dryness questionnaire (SPEED)*

The SPEED questionnaire was designed to make a rapid evaluation of dry eye symptoms [33]. It assesses whether these symptoms were not problematic, tolerable, uncomfortable, bothersome, or intolerable [34]. Also monitored diurnal and symptoms changes over 3 months [35]. The sensitivity and specificity of SPEED test versus OSDI were 0.90 and 0.80 respectively [35].
