Case Report: Bilateral Corneal Ectasia Developed during Pregnancy after Small‐incision Lenticule Extraction

Optometry and Vision Science, Volume 99, Issue 6, Page 528-533, June 2022., 2022
SIGNIFICANCE This case highlights that hormonal changes during pregnancy could affect the biomechanical stability of the cornea and lead to corneal ectasia during pregnancy after corneal refractive surgery. PURPOSE We report an unusual case of bilateral corneal ectasia after small‐incision lenticule extraction that developed during pregnancy.
