Which of the following is not a surgical treatment for refractive error?

Explanation:
The main idea here is to distinguish between surgical and non-surgical methods that correct refractive errors. Corneal Refractive Therapy (CRT) is not a surgical procedure. It uses specially designed rigid gas-permeable contact lenses worn overnight to temporarily reshape the cornea and reduce refractive error during the day. The changes are reversible if you stop wearing the lenses, and they require ongoing use to maintain the effect. In contrast, LASIK, PRK, and LASEK are surgical approaches that permanently alter the cornea’s shape. LASIK creates a corneal flap and uses laser to remove tissue beneath it, PRK removes the surface cells and then reshapes the underlying cornea with laser, and LASEK loosens the epithelial layer with alcohol before reshaping. These involve tissue modification and healing, which is why they’re classified as surgical. So CRT is not a surgical treatment, making it the correct choice for this item.
