The usual hormonal impregnation during the last two trimesters of pregnancy can lead to slight changes in the water content of the cornea and, thus, reversibly alter vision. It is therefore not advisable to perform myopia surgery, or refractive surgery, during this period and in the 3 months following childbirth to Hormone blood. On the other hand, it is not exceptional for a woman to discover that she was very early in her pregnancy at the time of the surgery, and this has no consequence because the cornea is at this stage in its “normal” state.
Up To What Level Of Myopia Can We Do LASIK, And Why?
In LASIK laser myopia surgery, eye lens replacement surgery, the cornea’s center will be thinned and flattened. These two actions have a limit: we cannot thin the cornea beyond a certain limit which would risk weakening it, and we cannot infinitely flatten the surface of the central cornea, at the risk of causing optical aberrations, an alteration of the quality of vision. These two notions generally limit the level of operable myopia to 10 diopters, but this is obviously to be modulated individually for each patient:
– we can sometimes operate on myopia slightly exceeding 10 diopters if the morphological conditions are optimal: very thick and sufficiently curved cornea.
– we can reject a patient with small myopia if the corneal morphology is not favorable, whether it is a very thin and already very flat cornea or conversely a very curved cornea and irregular, letting fear a risk, even distant, of ectasia.
Should You “Go Up” To Paris, For Example, For A Myopia Operation?
No, refractive surgery is performed today in many refractive surgery centers. In Paris, as elsewhere, high-quality equipment is available to surgeons in centers entirely dedicated to this surgery. The regrouping of surgeons in large centers such in kraff eye institute for example and the provinces, however, makes it possible to constantly update constantly changing equipment. In Paris, as elsewhere, it is necessary to privilege the contact and the capacity of the surgeon to answer the questions you ask yourself on the operations of myopia.
The future will tell us what place the ReLEx technique, still recent, can take in the arsenal of myopia surgery techniques, and in particular, what its place will be for patients considered, because of their corneal morphology, as patients at risk for Lasik.
