Definition
Noun: A type of refractive eye surgery that uses a laser to reshape the cornea. It is a specific procedure related to vision correction.
Usage
"Lasek" is used as a countable noun to refer to the medical procedure itself. It is often discussed in medical, optometric, or personal healthcare contexts.
Examples
- The ophthalmologist recommended Lasek as a potential alternative to LASIK for the patient with thin corneas.
- After her Lasek surgery, her vision improved dramatically.
- He is researching the differences between Lasek and PRK.
Advanced Usage
- Undergo Lasek: This is the most common collocation when describing having the procedure.
- She decided to undergo Lasek to correct her nearsightedness.
Variants and Related Words
- LASIK (noun): A more common and different type of laser eye surgery (Laser-Assisted in Situ Keratomileusis). It involves creating a corneal flap, unlike LASEK/Lasek.
- PRK (noun): Photorefractive Keratectomy, another surface ablation procedure similar to Lasek.
- Refractive surgery (noun): The general category of surgical procedures, including Lasek, to correct vision.
- Epithelial flap (noun): In Lasek, the surgeon loosens and moves aside a very thin layer of corneal epithelium (the surface cells) instead of cutting a deeper flap as in LASIK.
Synonyms
- Laser epithelial keratomileusis: This is the full technical name for the procedure, from which the acronym "LASEK" is derived.
- Surface ablation procedure: A broader term that includes Lasek and PRK.
Notes on Meaning
It is important to distinguish "Lasek" from the more frequently encountered "LASIK." While both are laser eye surgeries, they are technically different procedures. "Lasek" is sometimes written in all capitals as "LASEK," but it is commonly treated as a standard noun.
Noun
- a refractive surgery procedure that reshapes the cornea
