It is not good to have lasik surgery during pregnant because the prescription will keep changing during pregnant due to hormonal alterations. While lasik surgery require people to have stable vision so people whose vision is changing are not suitable for lasik surgery. Besides, if you go to have lasik surgery, the surgeon will ask you to take antibiotic and cortisone drops before or after the surgery, which may cause a detrimental effect on the baby. So you are not suitable for lasik surgery during pregnant.

So, the correction a woman gets while pregnant might no longer work once she has her baby and stops breastfeeding.
