Hi Jo
Congratulations! It would be best to wait until after you finish breastfeeding to have LASIK done. The main reason is that hormonal changes during this period of time may continue to affect stability of your spectacle power while breastfeeding, hence possibly leading to a less accurate LASIK treatment. The bigger risk is during pregnancy, but many ophthalmologists have concerns regarding stability of spectacle power during breastfeeding as well.
There is no specific concern regarding the use of most eyedrop medications (including steroid eyedrops), during pregnancy or while breastfeeding, as Dr Jasmine points out. This is because the amount absorbed into the body via eyedrops is so small as to be negligible, with regard to exposure to the baby.
