Keratotomy - English Definition & Meaning

Definition

A keratotomy is a surgical procedure involving making incisions in the cornea, the clear front part of the eye. 🤓 This is often done to correct astigmatism, a condition where the cornea is irregularly shaped, causing blurred vision. Think of it like reshaping the lens of a camera to focus better. The incisions help to flatten the steeper parts of the cornea, improving focus. It's a type of refractive surgery aimed at reducing the need for glasses or contacts. Radial keratotomy (RK) was a common early form, but newer techniques are more precise. 😎

Etymology

The word 'keratotomy' comes from 'kerato-' (from the Greek 'keras,' meaning 'horn' or 'cornea') and '-tomy' (from the Greek 'tomē,' meaning 'cutting' or 'incision'). Therefore, 'keratotomy' literally means 'cutting of the cornea,' describing the surgical procedure of making incisions in the cornea.
