LASIK stands for which procedure?

• A. Laser-Assisted In Situ Keratomileusis
• B. Laser-Assisted In Situ Keratectomy
• C. Laser-Assisted Intraocular Keratoplasty
• D. Laser-Assisted In Situ Corneal Ablation

Answer: (A)

This question tests understanding of what LASIK stands for and what the procedure entails. LASIK stands for Laser-Assisted In Situ Keratomileusis. Here, laser-assisted means the corneal tissue is reshaped with a laser. In Situ means the reshaping happens in place on the cornea, not after removing tissue from elsewhere. Keratomileusis combines kerato-, the cornea, and mileusis, meaning carving or shaping. In practice, a corneal flap is created and lifted, the underlying stroma is reshaped with an excimer laser, and then the flap is replaced to alter the corneal curvature and correct refractive errors like myopia, hyperopia, or astigmatism. The other terms describe different concepts: keratectomy would imply removing corneal tissue, intraocular keratoplasty refers to a corneal transplant inside the eye, and corneal ablation is a general term for tissue removal not specifically the LASIK reshaping procedure.
