LASIK surgery is a well-established procedure for correcting common refractive errors like myopia, hyperopia, and astigmatism by reshaping the cornea. This reshaping permanently alters the cornea's structure, aiming to improve uncorrected vision and decrease reliance on external aids like glasses or contact lenses. However, LASIK is generally not recommended for very young children or individuals whose eyes are still developing or whose prescriptions are unstable; specific age and health criteria must be met.
