The relationship of pre-corneal to pre-contact lens non-invasive tear breakup time. [PDF]
PLoS One, 2021 Purpose To examine the relationship between pre-corneal and pre-contact lens tear film stability (TFS), and to determine whether pre-corneal TFS is a reliable predictor of subsequent pre-lens TFS after a contact lens is placed on the eye. Methods 667 records met inclusion criteria and were extracted from a soft contact lens multi-study database ...

The Effect of Age and Gender on Tear Film Breakup Time [PDF]
Egyptian Journal of Medical Research, 2021 Background: Dry eye is a very common yet often mis-diagnosed ocular disorder. The stability of the tear film plays an important role in the integrity of ocular surface.

Short Tear Breakup Time Could Exacerbate the Progression of Presbyopia in Women. [PDF]
Biomed Res Int, 2022 Purpose. The contributory factors and symptoms for presbyopia progression have not been fully determined. The purpose of the study was to compare presbyopia progression in subjects with short and normal tear breakup time and to explore the severity of common ocular symptoms associated with presbyopia progression. Method.

Fluorescein tear breakup time predicts pre-lens tear film stability and contact lens comfort. [PDF]
J Chin Med AssocBackground: Soft contact lenses divide the tear film into pre-lens and post-lens layers. This study evaluated whether pre-lens tear film stability, assessed by fluorescein tear breakup time (TBUT) and noninvasive keratograph breakup time (NIKBUT), predicts subjective comfort.
