Trial Outcomes & Findings for Effectiveness of Intense Pulsed Light for Improving Dry Eye Syndrome (NCT NCT03396913)
NCT ID: NCT03396913
Last Updated: 2020-12-09
Results Overview
Change of Tear breakup time (TBUT) in the study eye, from baseline to follow-up. TBUT is measured in seconds. Higher values mean better outcome.

PRIMARY outcome
Timeframe: 10 weeksChange of Tear breakup time (TBUT) in the study eye, from baseline to follow-up. TBUT is measured in seconds. Higher values mean better outcome.

SECONDARY outcome
Timeframe: 10 weeksChange of self-assessed symptoms with the Ocular Surface Disease Index (OSDI) questionnaire, from baseline to follow-up. OSDI was collected per patient (one number per patient). The minimal number is 0 and the maximal number is 100. Higher scores mean worse outcome. A score of 0-12 is considered normal. A score of 13-22 is consistent with mild dry eye. A score of 23 to 32 is consistent with moderate dry eye. A score from 33 to 100 is consistent with severe dry eye.

SECONDARY outcome
Timeframe: 10 weeksChange of self-assessed symptoms on a visual analog scale (VAS) , from baseline to follow-up, in both eyes. Values were collected separately for each eye. Correlation between eyes was removed by statistical methods. Scores were 0 (minimum) to 100 (maximum). Higher scores = worse outcome. VAS scores are not validated for dry eye. Hence, it is not known how to correlate VAS values to severity levels of dry eye. However, one can make estimations from the literature of VAS in other conditions. For example, in patients with chronic musculoskeletal pain, in a VAS scale of 0 to 10 scores below 3.4 corresponded to mild pain, scores between 3.5 and 7.4 corresponded to moderate pain, and scores above 7.5 corresponded to severe pain. Using such results from other conditions, it is \*estimated\* that values between 0 and 34 correspond to mild symptoms, scores between 35 and 74 correspond to moderate symptoms, and scores above 75 correspond to severe symptoms.
