Most of the people haven’t clear meaning of the Laser operation but they somewhat clear that it is a surgery for eyes. Nowadays, this laser eye surgery is like a usual surgery doing by the doctors and prefers by the people. People avoid wearing glasses and contact lenses so that they prefer such an operation. Today, we have a variety of laser processes for astigmatism, farsightedness, and nearsightedness through the name of Laser Vision Corrections.
What are the procedures of Laser surgery?
The three types of refractive surgery are Photorefractive Keratectomy which is also referred to as PRK, Laser-assisted in-situ Keratomileusis which is also referred to as LASIK, and Small-incision lenticular extraction which is also referred to as SMILE.

- Photorefractive Keratectomy (PRK): Food and Drug Administration has approved this photorefractive keratectomy surgery. When they prefer the surgery an ophthalmologist takes away the layer of the cornea and then uses the laser. The reason behind such a laser is to reform the cornea into a new curving which is fit to the eye of the patient. This PRK is correlated with some post-procedure anxiety and the recovery time will be longer. Even though it is considered as the best option.
- Laser-assisted in-situ Keratomileusis (LASIK): After the 1990s this LASIK became the popularized refractive surgery. Dr. Dupps said that this became the second procedure while comparing to the first one because it has also received the same outcomes as Photorefractive Keratectomy. The surgeons use the flap to reach inside the cornea layers and then reshape it through the laser. But the slight difference is the recovery time (quicker) and less anxiety to the patients.
- Small-incision lenticular extraction (SMILE): for the nearsightedness patients, surgeons prefer this SMILE procedure of laser treatment with the need for a flap. They create some disk-shaped bit of tissue inside the cornea and then through the small incision that will be removed. It gives the native biometrical power to the cornea but this too will take long recovery time.
