KERATOTOME Meaning and
Definition
-
A keratotome is a surgical instrument that is used specifically for cutting or incising the cornea, which is the transparent, outermost layer of the eye. The word "keratotome" is derived from the combination of two Greek terms: "kerato," meaning cornea, and "tome," denoting an instrument used for cutting.
The keratotome typically features a small, sharp, and slender blade that is specifically designed to create precise and controlled incisions on the cornea during certain eye surgeries. These surgeries may include procedures like corneal transplants, refractive surgeries (such as LASIK or PRK), and certain types of glaucoma treatment.
As the blade of the keratotome is extremely thin and sharp, it allows surgeons to make accurate and controlled cuts in the cornea with minimal damage to the surrounding tissues. This precision is vital, as the cornea plays a crucial role in maintaining clear vision by refracting light entering the eye.
Furthermore, keratotomes often have a handle that provides a comfortable grip and control to the surgeon during the procedure. Some newer versions may incorporate advanced features, such as disposable blades or additional mechanisms that enhance safety and ease of use.
Overall, a keratotome is an essential instrument used in ophthalmic surgery for precise corneal incisions, ultimately contributing to improved surgical outcomes and visual correction.
