Can I have laser eye surgery if I'm pregnant or breastfeeding?

Many women ask whether they can have laser eye surgery while pregnant or breastfeeding. The short answer is that it is usually best to wait. Although laser vision correction is a safe and well-established procedure, pregnancy and breastfeeding bring physical changes that can affect the accuracy of measurements and the stability of the result. Most surgeons recommend delaying treatment until after you have finished breastfeeding and your body has returned to its normal state.

Why pregnancy affects the eyes

Pregnancy causes significant hormonal changes that can affect many parts of the body, including the eyes. These changes are usually temporary and settle after delivery or after breastfeeding ends. The two main concerns for laser eye surgery are changes in prescription and changes in the tear film.

Hormonal changes and prescription

The hormonal shifts of pregnancy can cause fluid shifts in the cornea, making it slightly thicker or changing its shape. This can lead to a temporary change in glasses or contact lens prescription. If laser surgery is performed while the cornea is in this altered state, the treatment may be based on measurements that do not match the eye once things settle down. This increases the chance of needing an enhancement later or being left with a small residual prescription.

Dry eye during pregnancy and breastfeeding

Many women notice dry eye symptoms during pregnancy and while breastfeeding. Hormones affect the tear film and the glands that produce tears, which can lead to gritty, uncomfortable or watery eyes. Laser eye surgery, particularly LASIK, can cause temporary dry eye after treatment. If your eyes are already dry before surgery, the symptoms may be more pronounced and take longer to settle. For this reason, we prefer the tear film to be stable before planning surgery.

Safety of the procedure

There is no evidence that laser eye surgery harms an unborn baby, but the procedure is elective and can safely be postponed. The main issue is not safety to the baby, but the quality and predictability of the outcome for the mother. Pregnancy also makes lying flat for the procedure less comfortable, and the anxiety some people feel may be harder to manage during pregnancy. We also avoid the sedative and anaesthetic eye drops used during treatment unless absolutely necessary.

When is the best time?

The ideal time to have laser eye surgery is after your pregnancy and once you have finished breastfeeding. Most surgeons recommend waiting at least three months after stopping breastfeeding, or sometimes longer, to allow your hormones, prescription and tear film to return to a stable baseline. This gives us the most accurate measurements and the best chance of a long-lasting result.

Breastfeeding considerations

Breastfeeding can also affect the eyes and prescription. Hormones involved in milk production may keep the tear film unstable and the cornea slightly changed. For this reason, we usually advise waiting until breastfeeding has ended before performing laser eye surgery. If you are keen to proceed while breastfeeding, this would be discussed carefully, but it is not generally recommended.

Alternatives to consider

If you rely on glasses or contact lenses and are pregnant or breastfeeding, the safest option is to continue with your current correction until your eyes are stable. Make sure your contact lens prescription and lens type are still comfortable, as dry eye can make lens wear more difficult. If your prescription has changed, a temporary update to your glasses may be the best solution until after breastfeeding.

What to do if you are pregnant or breastfeeding

If you are currently pregnant or breastfeeding, mention this at your assessment. A good surgeon will advise you to wait rather than push you towards surgery. You can still have an initial consultation to learn about the procedure, but the actual measurements and treatment should be delayed until your eyes are stable. Bring a note of when you expect to finish breastfeeding, and we can plan a timeline for reassessment.

Next steps

If you are pregnant or breastfeeding, the best next step is to wait until your hormones have settled and your tear film is stable. Book a comprehensive laser eye surgery assessment once you are at least three months past breastfeeding. At that visit we can take accurate measurements, discuss your options and plan treatment with the best chance of a clear, comfortable result.
