The Influence of Hormonal Changes During Pregnancy on Corneal Biomechanics in Humans

To measure corneal biomechanics, specifically corneal hysteresis (CH) and the Corneal Resistance Factor (CRF). The devise measures in a non-contact manner, by analyzing the deformation of the cornea upon a defined pulse of air.

A Scheimpflug camera will be used in a non-contact manner to assess topographical data from the anterior and posterior corneal surface as well as detailed data on corneal thickness.

A blood sample will be taken at 6 months after surgery to determine the levels of several hormones. The blood needed to détermine hormone levels during pregnancy will be acquired during the routine examinations that are performed during pregnancy. Here, blood is taken routinely and an additional volume is taken for the purpose of this study.
