    Watch the video on lasik. Which statement is true about lasik surgery?

    • During lasik surgery, the shape of the retina is changed.

    • Stitching of the eye is needed after lasik surgery.

    • The lasik surgery takes about 60 minutes.

    • Lasik surgery can treat near-sightedness.

    Correct Answer
    A. Lasik surgery can treat near-sightedness.
    Explanation
    Lasik surgery is a procedure used to correct vision problems such as near-sightedness, far-sightedness, and astigmatism. It involves reshaping the cornea, not the retina, to improve the way light is focused onto the retina. Stitching of the eye is not required after lasik surgery as it is a minimally invasive procedure. The duration of the surgery is typically around 15 minutes per eye, not 60 minutes. Therefore, the correct statement is that lasik surgery can treat near-sightedness.
