During pregnancy, the body undergoes a number of changes, many of them linked to rising estrogen levels.
The eyes can also undergo various changes during pregnancy, such as fluctuations in intraocular pressure, reduced tear production, changes in prescription and alterations in other structures such as the lens and the cornea. These changes may be linked to the presence of estrogen receptors in these structures, which are more stimulated during pregnancy.
Due to fluid retention during pregnancy, the cornea can become edematous (accumulate fluid), which in turn can alter corneal curvature and lead to changes in prescription (blurred vision). These changes usually resolve after childbirth or breastfeeding, so they do not require any specific treatment.
However, blurred vision in pregnant women can be a sign of a systemic condition such as preeclampsia (high blood pressure during pregnancy) or gestational diabetes. If these symptoms appear, it is advisable to see a doctor to rule out these disorders.
Because of these changes in prescription, we advise against refractive surgery during pregnancy and breastfeeding. However, since the changes are temporary in most cases, there is no contraindication to laser corneal surgery (LASIK, PRK) before pregnancy.
In addition, reduced tear production can cause dry eye symptoms such as stinging, itching, a foreign body sensation and contact lens intolerance. Our center has a specialist unit to treat these complaints.
