Someone mentioned that after pregnancy, due to hormonal changes, her number came back and therefore it is better to do LASIK after having kids. Does that happen in certain cases?
No, the glasses number never reverses totally, in very few people some slight number (-0.5 to -0.75) may come, not due to decrease in laser effect but due to increase of the inherent number. Hormones not only in pregnancy but sometimes even higher doses due to hormonal imbalance like in hirsuitism etc can lead to slightly fluctuating numbers. However, this does not happen to everyone, and neither is there any predictor in whom it may happen. Studies indicate that those on hormones, even oral contraceptive pills and pregnancy can have slight variation in numbers. In our practice we have not seen this happen. The possibility of needing an enhancement or re treatment has to be then explored. Though we do not recommend having Lasik during pregnency or till three months after delivery, numbers coming back after pregnency are as uncommon as glasses number increasing after each pregnency. We have had only 2 such cases in past more than a decade. These too were retreated free of cost by Lasik
