Comparing Tear Proteomics Profile in Dry Eye Disease pre-and Post-treatment With Low Level Light Therapy

Singapore National Eye Centre

Status: Enrolling

Conditions: Dry Eye; Meibomian Gland Dysfunction (Disorder)

Study type: Observational

Funder types: Other

Identifiers

NCT07329712

Details and patient eligibility

About

The purpose of this research study is to understand the mechanism of action of low level light therapy and also potentially yield markers associated with good treatment response. Low-level light therapy is light-based treatment delivered through advance eye-light device. This therapy uses light energy to provide energy to the meibomian gland cells to slow down age-ing, improve tear stability and reduce inflammation.

Enrollment: 30 estimated patients
