Under and over corrections are common after which type of surgery?

Under and over corrections are commonly associated with muscle surgeries, specifically those involving the extraocular muscles that control eye movement. After muscle surgery, adjustments in the alignment of the eyes can sometimes lead to either excessive correction or insufficient correction of strabismus (misalignment of the eyes).

In muscle surgery, the goal is often to reposition or strengthen certain muscles to achieve proper ocular alignment. However, the outcome can be unpredictable, as it may require precise measurement and surgical technique. Factors such as healing responses, residual muscle tonus, or even the brain's adaptation to the new eye positioning can influence the final result, hence leading to under or over corrections.

Corneal surgeries, like LASIK or other refractive procedures, focus more on the shape of the cornea and the overall refractive error rather than muscle alignment. While cataract surgeries also involve lens adjustments, they do not have the same issues with muscle corrections. Lens surgeries involve replacing or altering the lens of the eye without directly dealing with the ocular muscles, which is why muscle surgery stands out in this context.
