Effect of Preserved Versus Preservative‐Free Artificial Tears on the Corneal Epithelial Thickness Mapping by MS‐39 in Dry Eye Patients

Journal of Ophthalmology, Volume 2026, Issue 1, 2026.
Purpose To compare clinical and corneal epithelial changes between preservative and preservative‐free artificial tear therapy using the MS‐39 in patients with dry eye disease (DED). Methods This prospective interventional comparative study included 88 eyes of 44 patients. Preserved artificial tears were given for the left eye (group A) and preservative‐

Biomechanical behaviour - Anisotropy of eye cornea through experimental strip tests [PDF]

, 2018
With the advent of research it was identified that material properties are responsible for errors in tonometry pressure (referred to as Goldmann IOP or IOPG) with the stiffening of a composite structure of corneal tissue in particular.
