Clinical Trial Summary

To evaluate the influence of corneal-aberrations before and after the meibomian gland thermal massage treatment.

Description:

62 MGD patients treated with meibomian gland thermal massage once a week for 3 to 4 weeks were recruited.The Ocular Surface Disease Index questionnaire; tear film assessment encompassing tear meniscus height and non-invasive keratograph breakup time ; meibography score,corneal fluorescein staining; the Schirmer I test ; expressible meibomian gland, and quality ,anterior and total corneal aberrations were evaluated before and after treatment.
