Study of Therapeutic Bandage Type Contact Lens in the Treatment of 27 Cases of Severe Tear and Evaporative Dry Eye / 现代医院

ABSTRACT

Objective To investigate the value of therapeutic bandage type contact lens in the treatment of severe dry tear with dry eye. Methods 54 cases of severe tear evaporative dry eye patients from January 2016 to April 2017 were randomly divided into observation group (27 cases) and control group (27 cases). The observation group received the treatment of artificial tears combined with bandage contact lens treatment, the control group only received the treatment of artificial tears. Continuous treatment trials compared two groups of symptoms score, tear secretion after 1 months (SⅠt, SⅡt), tear break-up time (break up, time, BUT) and tear ferning test (tear ferning, test, TFT). Results After treatment, the scores of the two groups were decreased, and the observation group was lower than the control group. The difference was statistically significant (P＜0. 05); the levels of SⅠt, SⅡt and BUT were improved in both groups, and the improvement effect was better in the observation group (P＜0. 05); The detection level of TFT in the observation group was better than that in the control group, the difference was statistically significant (P＜0. 05). Conclusion The treatment of bandage contact lens in severe tear evaporation effect in treatment of patients with dry eye in strong type is effective and able to significantly improve their symptoms score and SⅠt, BUT and TFT index.
