Which procedure is commonly abbreviated LASIK?

• A. Laser In-Situ Keratomileusis
• B. Laser Epithelial Keratomileusis
• C. Laser Assisted Sub-Epithelial Keratectomy
• D. Laser Keratotomy

Answer: (A)

LASIK is an acronym that directly describes how the procedure is done: Laser In-Situ Keratomileusis. Here, “laser” refers to the excimer laser used to reshape the cornea, “in-situ” means the cornea is reshaped in its original place after a flap is created and lifted, and “keratomileusis” means sculpting the cornea. This combination defines the common refractive surgery where a corneal flap is made, the underlying tissue is reshaped with the laser, and the flap is laid back into place for vision correction. The other terms describe different techniques that don’t form the LASIK acronym or the same approach. For example, a procedure named with epithelial keratomileusis emphasizes reshaping after epithelial alteration rather than the corneal flap method used in LASIK; a laser-assisted sub-epithelial keratectomy refers to surface-level reshaping without the same flap mechanics; and keratotomy involves incisions rather than laser ablation to achieve refractive change. So the term that is commonly abbreviated as LASIK matches Laser In-Situ Keratomileusis.
