Automated lamellar keratoplasty

Automated Lamellar Keratoplasty (pronunciation: au·​to·​mat·​ed | \ ˈȯ-tə-ˌmā-təd, la·​mel·​lar | \ lə-ˈme-lər, ker·​a·​to·​plas·​ty | \ ˌker-ə-tō-ˈpla-stē) is a type of refractive surgery that is used to correct myopia (nearsightedness). The term originates from the Greek words 'automatos' (self-acting), 'lamella' (thin layer), 'kerato' (cornea), and 'plasty' (formation).

Procedure

In Automated Lamellar Keratoplasty (ALK), a microkeratome, a precision surgical instrument with an oscillating blade, is used to cut a thin flap in the cornea. The surgeon then removes a layer of corneal tissue beneath the flap using the same microkeratome or a different one, and finally, the flap is repositioned on the cornea without sutures.
