It is known that intraocular pressure changes during pregnancy. Collagen structure changes during pregnancy to enable softening of the symphysis, whitening of the birth chanel, and, thus, ultimately to enable delivery of a child. The cornea consists of highly structured collagen fibers. Hence, it seams logically that corneal biomechanics also change during pregnancy.
