Effect of Obstructive Sleep Apnea on Corneal Morphological Characteristics.

Purpose: To determine central corneal thickness (CCT) and the corneal parameters in patients with obstructive sleep apnea (OSA), evaluate the relationship between the severity of OSA, minimum peripheral capillary oxygen saturation (min. SpO2), and corneal morphological characteristics.

Methods: Patients with OSA diagnosed by full-night polysomnography before treatment were included.

Endothelial parameters in central and peripheral cornea in patients wearing contact lenses.

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.
