Summary
The main objective of this Master's Thesis is to evaluate the impact of Contact Lenses (CL) on the Meibomian Glands (MG) and tear stability through a cohort study composed of 37 participants with a mean age of 22.8 years. The sample included 67.6% women and was divided into CL users (n = 19) and non CL users (n = 18) to analyze the symptomatology and signs of ocular surface (OS) alteration using clinical tests and specific questionnaires. The results determined that there is significant evidence of an increased area of glandular loss (p=0.048) and a higher degree of MG obstruction (p=0.016) in the CL user group. However, the lipidomic analysis found no differences in meibum composition between the CL user group and the non user group.
