sharing my experience as well.
i just did my lasik surgery earlier this week and my baby boy is 10 weeks old now.
I did have concerns about the changes in cornea shape or hormonal changes, but after reading articles online and consulting GP, Gynae and the eye surgeon, have decided to go ahead with it.
According to the 3 sources above, would suggest to do it after you have given birth as your cornea shape does change during pregancy - due to the water retention (swelling) and hormonal changes.
After birth, once all the swelling has gone away, then it would also indicate that the cornea has returned to normal.
I called up several clinics, including TTSH and SNEC on this, and it really depends on the eye surgeon "operating" on you. I know there are 2 surgeons in SNEC who are against pregnant woman and breastfeeding moms doing lasik. So really depends on the eye surgeon.
Also, as im breastfeeding my son, I also concern about the eye drops as it contain steriod. But my GP reassure me that even though the eye drops contain little % of steriod, by the time it got into the breast milk, its minimal.
I did mine in a pte clinic in paragon medical, called the lasik surgery centre.
No regrets on doing it - now dun have to fumble for glasses when breastfeeding baby son at night and also expressing milk.
