PHOTOKERATECTOMY Meaning and
Definition
-
Photokeratectomy is a surgical procedure aimed at correcting refractive errors of the eye, such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism, using the power of laser technology. It is a form of laser vision correction that involves reshaping the cornea, the clear front surface of the eye, to improve visual acuity and reduce the reliance on eyeglasses or contact lenses.
During the photokeratectomy procedure, a specialized laser is utilized to remove a thin layer of tissue from the cornea. The removal of this tissue alters the shape of the cornea, allowing light to properly focus on the retina, leading to improved vision. The precise amount of tissue to be removed is determined by the individual's unique refractive error and desired outcome.
Photokeratectomy is a highly customized procedure that requires careful evaluation of the patient's eye health, corneal thickness, and overall eye anatomy. It is typically performed in an outpatient setting, and local anesthesia is used to minimize any discomfort. Following the procedure, patients may experience temporary side effects such as dryness, glare, or halos around lights, but these usually subside over time.
Photokeratectomy has revolutionized the field of ophthalmology by providing an effective and lasting solution to common refractive errors. It has become a popular choice for individuals seeking to achieve clearer vision without the need for corrective eyewear. Proper evaluation by an experienced eye surgeon and thorough understanding of the procedure are essential before considering photokeratectomy to ensure optimal outcomes and satisfaction.

Etymology of PHOTOKERATECTOMY
The word "photokeratectomy" is derived from two Greek roots: "photo" and "keratectomy".
- The root "photo" comes from the Greek word "phos" (φῶς), meaning "light". It is often used as a combining form in medical terminology to refer to light-related procedures or treatments.
- The root "keratectomy" is derived from the Greek word "keratos" (κέρατος), which means "horn" or "cornea". In medical terminology, "-ectomy" typically denotes a surgical removal or excision. Therefore, "keratectomy" refers to the surgical removal or reshaping of the cornea.
