Completed
Conditions
Meibomian Gland Dysfunction
Registration Number
NCT05028491
Lead Sponsor
Wenzhou Medical University
Brief Summary

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

Detailed 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.

Primary Outcome Measures
NameTimeMethod
corneal aberration corneal aberrationsbaseline and 1 week after treatment

Corneal aberrations were measured with a Pentacam。 The anterior corneal wavefront aberration was expanded with normalized Zernike polynomials.The corneal aberration from 3rd to 6th order were recorded as the root mean square (RMS) for analysis.
