PRK Eye Surgery

Photorefractive Keratectomy, commonly known as PRK surgery, is a type of laser eye surgery that is used to correct vision problems caused by refractive errors such as nearsightedness, farsightedness and astigmatism. This surgical procedure involves reshaping the cornea, which is the clear dome-shaped outer layer of the eye, to improve visual acuity. PRK surgery was first introduced in the early 1980s and has been continuously improving over time.

How PRK Surgery Works ‍

During PRK surgery, an excimer laser is used to reshape the cornea. The surgeon first removes the thin outer layer of the corneal tissue, known as the epithelium. This layer grows back naturally within a few days after surgery. Then, the excimer laser is used to precisely remove small amounts of tissue from the underlying corneal tissue. The goal of the surgery is to change the shape of the cornea so that light can be properly focused on the retina, resulting in improved vision.

‍Advantages and Disadvantages of PRK Surgery ‍

One of the main advantages of PRK surgery is that it does not involve creating a flap in the cornea like other types of laser eye surgeries such as LASIK. This makes it a better option for people with thinner corneas or other eye conditions that may make flap creation risky. PRK surgery also has a lower risk of complications compared to other forms of laser eye surgery.

One disadvantage of PRK surgery is that the recovery period can be longer than other laser eye surgeries. The outer layer of the cornea takes a few days to regenerate, during which time the patient may experience discomfort and blurry vision. It may take a few weeks for full recovery and visual acuity to be achieved.

The Bottom Line ‍

PRK eye surgery is an effective and safe option for correcting refractive errors and improving vision. It offers advantages such as a lower risk of complications and suitability for patients who may not be eligible for other types of laser eye surgery. However, it may also have a longer recovery period compared to other procedures.
