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?
- ALASIK procedure is used to correct refractive errors of the eye
- BIt is a procedure that permanently changes the shapes of the cornea
- CIt reduces a person’s dependence on glasses or contact lenses
- DIt is a procedure that can be done on the person of any ageCorrect
Explanation
The correct option is D because LASIK cannot be performed on persons of any age. Candidates must typically be at least 18 years old, although many surgeons prefer waiting until age 21, because the eyes continue to change and the prescription must be stable for at least one to two years before surgery. Additionally, it is generally not recommended for very elderly patients if they have developed cataracts or other age related eye conditions that affect the outcome. Options A, B, and C are correct descriptions of the procedure as it reshapes the cornea to treat refractive errors like myopia and hyperopia, thereby reducing the need for corrective eyewear.
