Yes, the effects of SMILE (Small Incision Lenticule Extraction) surgery are considered permanent in that the refractive correction achieved is long-lasting and irreversible.
While SMILE permanently reshapes the cornea to correct refractive errors like nearsightedness and astigmatism, it's important to understand what "permanent" means in this context:
-
Correction is Long-Lasting: The intended correction of your vision (e.g., eliminating the need for glasses or contacts to see clearly at a distance) is generally considered permanent. Most patients experience stable vision for many years after the procedure.
-
Irreversible Procedure: The physical alteration of the cornea through the removal of the lenticule is permanent. The removed corneal tissue cannot be replaced.
-
Doesn't Prevent Age-Related Changes: SMILE corrects existing refractive errors. It doesn't prevent future age-related vision changes like presbyopia (the need for reading glasses as you get older) or the development of cataracts. You might still need vision correction later in life for these separate conditions.
-
Retreatment Options: While the initial SMILE procedure is considered permanent, enhancements or retreatments might be possible if a slight under-correction or regression occurs. These options would depend on the individual case and corneal thickness.
In summary, SMILE provides a long-lasting and irreversible correction of your current refractive error. However, like any surgery, it's crucial to have realistic expectations and understand that it doesn't guarantee perfect vision for life, especially considering the potential for age-related vision changes. Consulting with a qualified ophthalmologist is vital to assess your individual suitability and understand the potential risks and benefits.
