LASIK stands for Laser-Assisted In Situ Keratomileusis (say that 10 times fast). It’s an eye procedure that permanently changes the shape of the cornea, which is the clear covering in the front of your eye. Unfortunately, it is not safe in pregnancy or breastfeeding.
Interestingly, the thickness of the cornea changes during pregnancy1 , which is thought to be a response to fluid retention or to the sex hormones circulating in pregnancy. In addition, the curvature of the cornea increases both during pregnancy and breastfeeding. So why is this important? Well, as mentioned, Lasik surgery reshapes the cornea. If you get that done while pregnant or breastfeeding, then Lasik could improperly change the shape of your eye and your vision could permanently be suboptimal.
