Definition

Noun: A specific type of refractive eye surgery. LASIK is an acronym for Laser-Assisted In Situ Keratomileusis. It is a procedure where a surgeon uses a laser to permanently change the shape of the cornea, which is the clear covering at the front of the eye, to improve vision and reduce a person's dependency on glasses or contact lenses.

Usage

• LASIK is used as a proper noun to name the specific surgical technique. It is often used without an article (e.g., "to have LASIK") or with "surgery/procedure" (e.g., "LASIK surgery").
• It describes both the procedure itself and the concept of undergoing this type of vision correction.

Examples

Advanced Usage

• Custom LASIK: A more advanced form of the surgery that uses detailed wavefront measurements to map the eye's unique imperfections for a more personalized treatment.
• LASIK enhancement: A follow-up procedure sometimes performed to fine-tune the initial surgical results if vision is not fully corrected.
