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 ?

Result
Your answer: —  Â·  Correct: D
Explanation

Option 4 is not correct. LASIK is a laser refractive procedure that reshapes the cornea to correct refractive errors (myopia, hyperopia, astigmatism) and commonly reduces dependence on glasses or contact lenses. The procedure permanently changes corneal shape to improve how light focuses on the retina, though natural ageing of the eye (for example presbyopia starting around the 40s) can alter vision later [1]. Importantly, not everyone is an automatic candidate: most centres require mature, stable refraction and sufficient corneal thickness (commonly age 21+ is mentioned as an optimal minimum), and other ocular conditions can disqualify a person. Therefore LASIK cannot be done on persons of any age without evaluation.
