Clearly KC host Dr. Melissa Barnett OD visits with Dr. Suzanne Sherman OD, Associate Professor in the Department of Ophthalmology at Tampa’s University of South Florida.  Dr. Sherman and Dr. Barnett discuss the impact of estrogen and progesterone on vision.  Increased hormone level resulting from pregnancy can lead to many changes in the body, including decreased stiffness in the cornea, increasing the bending and shifting that is common in keratoconus.  Dr. Barnett agrees that doctors should educate all patients of the possibility of temporary vision changes during pregnancy and the post-partum period so that patients will not be alarmed.
