What is Laser surgery?

ophthalmologists will recommend laser surgery as it is beneficial for you and helps you in getting rid of eye problems. The doctor will treat your eye problem by using special light beams.

If you are suffering from eyesight problems, then you should visit the best eye hospital near you. Laser methods can also correct refractive errors. 4 refractive errors are mentioned below:

  • Myopia

Myopia is also called nearsightedness. Patients suffering from myopia are unable to see the objects clearly that are far from them. The picture of any object focuses in front of the retina instead of on the retina.

  • Astigmatism

This is a situation in which a person will see blurry objects from any distance. The light will not focus evenly on the retina of the patient.

  • Hyperopia

Hyperopia is also known as farsightedness. The person can see the far objects properly but unable to see the close objects as it becomes blurry. In this, the person’s eyeball becomes shorter and the cornea becomes too flat. The image of an object’s focus behind the retina.

The flap is then folded back disclosing the middle section of the cornea. Also from a computer-controlled excimer laser detach the part of the stroma.
  • PRK stands for photorefractive keratectomy. In this, the eye specialist will remove tiny amounts of tissue from the outer surface using a laser to remove the cornea & reshape it.
  • LASEK stands for laser epithelial keratomileusis. This involves both LASIK as well as PRK procedures. This surgery is beneficial for the patient who cannot undergo Lasik. There is no need for cutting flaps in this.
