Recently, LASIK (Laser Assisted In Situ Keratomileusis) procedure is being made popular for vision correction. Which one of the following statements in this context is not correct?

1. LASIK (Laser Assisted In Situ Keratomileusis) is a surgical procedure used to correct vision problems. 2. Statement (A) is correct: LASIK is specifically used to correct refractive errors of the eye, such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. 3. Statement (B) is correct: The procedure involves using a laser to reshape the cornea, which permanently changes its shape to improve how light is focused onto the retina. 4. Statement (C) is correct: By correcting the underlying refractive error, successful LASIK significantly reduces or eliminates a person's dependence on glasses or contact lenses. 5. Statement (D) is incorrect: LASIK is generally not performed on individuals under the age of 18-21 because their eyes and vision may still be changing. There can also be upper age considerations or contraindications (like cataracts or other eye conditions). Therefore, it cannot be done on a person of any age. 6. The question asks for the statement that is not correct.
