Summary

Deficiency in tear film lipid layer thickness (LLT) has been implicated in the development of dry eye symptoms, and is influenced to a significant degree by the anatomy and function of the eyelids. Patients who are considering blepharoplasty, even if it is for cosmetic reasons, may subtle differences in eyelid anatomy that pre-dispose them to having an abnormal tear lipid layer. Moreover, the changes in anatomy and contour of the eyelids following blepharoplasty introduce a whole new group of factors, such as an altered palpebral aperture and altered canthal fixation that can further change the eyelid's ability to maintain a healthy tear lipid layer, for better or for worse. Such changes in tear lipid layer can be detected with the aid of a newly acquired tear interferometer (LipiView, Tearscience Inc.), but has never been done in the context of blepharoplasty management. Due to the strong association between LLT and risk of dry eyes, we hope to investigate if there are significant differences in LLT and other objective dry eye parameters in two situations: 1) patients considering blepharoplasty as compared to other patients not considering such procedures 2) patients before and after undergoing blepharoplasty. The results of these investigations can go towards establishing LLT as an important objective parameter to account for before and after blepharoplasty.

Interventions

DEVICE

Tear Science LipiView

The LipiView is a non-invasive instrument that captures live, special and digital images of your tear film and measures its lipid content and quality. This is a standardized test that quantifies your lipid to help your eye doctor determine if you should undergo the LipiFlow procedure or other tear therapies that would treat your condition. In effect, the LipiView allows your eye doctor to visualize your tear films.
