The Dry Centre of Regina in its quest for excellence to help explain your dry eye, utilizes Specular Microscopy to determine the health of the endothelium of your cornea. This single cell structure is responsible for the hydration of the stroma which makes up the bulk of your cornea. In abnormal cell counts there is a far greater likelihood of complications such as corneal edema and resultant loss of visual acuity that can be transient in nature.
