Assessments of tear meniscus height, tear film thickness, and corneal epithelial thickness after deep anterior lamellar keratoplasty. [PDF]

J Zhejiang Univ Sci B, 2018
To assess the lower tear meniscus height (LTMH), central tear film thickness (CTFT), and central corneal epithelial thickness (CCET) after deep anterior lamellar keratoplasty (DALK).This was a retrospective cross-sectional study of 20 patients who had DALK in one eye over a three-month period.

An investigation of the relationship between tear meniscus height and the subjective severity of ocular symptoms in keratoconus

African Vision and Eye Health, 2015
Keratoconus is a debilitating disease in which the cornea does not develop its characteristic round shape but develops into a conical form affecting both functional vision as well as ocular comfort. Depending on the severity of the keratoconus as well as the presence of any associated conditions, keratoconic individuals may complain of various ...
