Brief summary

This study will compare cataract patients before and after phacoemulsification. Evaluations will be performed before and 1 and 3 months following cataract surgery, including measurement of tear film lipid layer thickness, tear film break up time, Schirmer test, corneal and conjunctival fluorescein staining, examination of lid margins and meibomian glands, and the Ocular Surface Disease Index.
