Thân thiện

A surgeon performs radial keratotomy to correct a patient's vision.

Definition

Noun: - A surgical procedure for correcting nearsightedness (myopia) in which a series of radial (spoke-like) incisions are made in the cornea, causing it to flatten and thereby changing its refractive power.

Usage

• Noun:
  • Radial keratotomy was a common vision correction surgery before the advent of LASIK.
  • The ophthalmologist explained the risks and benefits of radial keratotomy to the patient.

Advanced Usage

• Historical Context: While largely superseded by laser-based procedures like LASIK and PRK, radial keratotomy represents a significant historical development in refractive surgery.
  • Radial keratotomy paved the way for modern laser eye surgery techniques.

Variants and Related Words

  • The patient's records indicated he had RK performed in the 1990s.
• Photorefractive keratectomy (PRK) (n): A later, laser-based surface ablation procedure for vision correction.
• LASIK (n): A later, laser-based flap procedure that has largely replaced radial keratotomy.
