Is LASIK Eye Surgery and Refractive Surgery are same

One of the million dollar questions in general is, whether LASIK Surgery and Refractive Surgery are the same. The myth behind this question ends up with an answer. Yes, they both are same.

The Scientific approach clearly states that LASIK is a sub-type of Refractive Surgery. It is a procedure to resolve the refractive index errors such as;

  • Myopia (Nearsightedness)
  • Hyperopia (Farsightedness)
  • Astigmatism

When these implications are corrected, your vision will improve completely.

Refractive Surgery involves correcting the shape of the cornea (re-shaping) with the help of a Laser. This helps in avoiding contact lens or power glasses.

Refractive surgery will be the perfect option for any patient who wants to,

  • Decrease their dependence on glasses or contact lenses.
  • Be free from eye disease.
  • Accept the inherent risks and potential side effects of the procedure.
  • Understand that they could still need glasses or contacts after the procedure to achieve their best vision.
  • Have an appropriate refractive error.

Is LASIK Eye Surgery and Refractive Surgery the same?

Basically, Refractive surgery can be classified into two types. They are,

  • LASIK (Laser-assisted in situ Keratomileusis)
  • PRK (Photorefractive Keratectomy)

They both are operated with the help of a laser to improve vision.

Photorefractive Keratectomy is a process of pealing the topmost layer of the cornea (epithelium). Generally, Cornea is composed of five thin and transparent layers. Once, PRK peals the outermost layer, with the help of a laser it corrects the other layers of the cornea. This procedure helps in fixing the irregular curvatures of the eye.

Laser-assisted in situ Keratomileusis is the process of creating a small flap in the cornea with the help of a laser or a thin blade. Once the flap is created, the eye surgeon uses the laser to reshape the curvature of the cornea. The best part in LASIK that is compared with PRK is, the flap will lower back to its original position and cure within a time period. So, there is no risk of losing the outermost layer of the cornea in LASIK surgery.

Thus, it is clear that LASIK surgery is a part of Refractive Surgery. LASIK is the most preferred treatment in Refractive Surgery.
