Endothelial parameters in central and peripheral cornea in patients wearing contact lenses
Journal Title: International Journal of Ophthalmology - Year 2018, Vol 11, Issue 11
Abstract
"AIM: To measure the parameters of endothelium in the central and peripheral parts of the cornea and evaluate the influence of wearing the hard and soft contact lenses on the mentioned parameters. METHODS: A specular microscope was used to measure the corneal endothelium parameters in both eyes of 139 Caucasians (a total of 278). All participants were divided into three groups: soft lens wearers, hard lens wearers and a control group. Factors, such as age, smoking, types of lens material, duration of lens wear and lens air permeability were assessed to determine their impact on the morphometric parameters of the endothelium. RESULTS: A lower percentage of hexagon-like cells and higher cell variation than in other groups were determined in hard contact lens wearers. The difference in density of endotheliocytes between the groups was not observed. The measurements of the morphometric parameters in soft contact lens wearers did not depend neither on the duration of lens wear, nor on air permeability. The relation between the patients’ age and the variation of endothelium parameters was determined in the group of hard contact lens wearers. CONCLUSION: Wearing hard contact lenses provokes pleomorphism and polymegethism of the corneal endothelium, while soft contact lenses do not impact any parameters of the endothelium, most likely due to higher air permeability."
