The Future of LASIK: Innovations in Technology and Techniques


LASIK, which stands for laser in-situ keratomileusis, is a common surgery that can correct the vision of people who are nearsighted, farsighted, or have astigmatism. If you’ve looked for eye LASIK surgeries, you’ve encountered different techniques to undergo it. So, you may have wondered which technique is better than the others!

This article will provide a complete guide regarding eye Lasik technology and its future. Are you interested to learn more? Keep reading!


What Are Different Types of Eye Lasik Techniques?

All types of eye Lasik surgery (LASIK, LASEK, Epi-LASIK, PRK, …) are performed to meet patients’ need for glasses or contact lenses. Regarding treatment safety, correcting refractive errors with glasses imposes the slightest risk on the patient, and contact lenses have the most risk. Meanwhile, surgical methods for refractive errors are relatively safe and have good visual results.

Here’s a list of standard eye Lasik techniques:

  • Lasik
  • Lasek
  • Epi-Lasek
  • PRK
  • Femto Lasik
  • Femto Smile

In the following, we explain each of these methods in detail.

All Types of Eye Lasik Surgeries




In LASIK, a thin sheet of the cornea called a flap is removed to eliminate the refractive errors in your eye, and then the laser operation is performed. After undergoing this operation, this thin sheet is put back in its place. Many people worldwide have used LASIK eye surgery to fix weak (lazy) eyes. Additionally, this method is approved by the FDA (Food and Drug Administration).



LASEK eye surgery is very similar to LASIK surgery for removing glasses. In this type of surgery, after removing the epithelium layer on the cornea’s surface and operating, this layer is returned to its place. This procedure is better for patients who have dry eyes.

Usually, LASEK is performed on people with the less corneal thickness or more corneal curvature and needs to be better candidates for LASIK. Usually, after the LASEK procedure, patients feel more pain and discomfort than with the LASIK method.

This technique is similar to LASEK. But in Epi-LASEK surgery, the specialists use an epi-keratome to create a skinny epithelium flap. This method’s superiority over conventional LASEK methods has yet to be proven, and there is not much desire among ophthalmologists to use this method.


PRK (Photorefractive keratectomy)

In the PRK procedure, the outer layer of the cornea (epithelium) is removed, and before the corneal tissue is reshaped, it is evacuated with an excimer laser. The epithelium repairs itself for a few days after surgery and covers the cornea’s surface again. This procedure suits patients with thin cornea dilated pupils or a cornea transplant.



This eye Lasik technique is also used to solve the problem of farsightedness, myopia, and astigmatism. Femtolysis is an advanced method of LASIK operation in which a “femtosecond laser” is used to create a cut; this device dramatically increases the operation’s speed, accuracy, and safety. This procedure is recommended for those who have high astigmatism or camera vision.


Femto-Smile: An Innovation in Eye Surgery

In the ReLex smile method or Femto Smile, laser light is used for precise cuts. In fact, in the Femto Smile method, laser light is used to create a tiny incision similar to the design of a smile on the cornea due to its high penetrating power and ability to be adjusted in exact cuts.

In Femtosmile, cutting the cornea’s surface is not done with a surgical blade as in the eye LASIK operation. In this laser surgery method, the surgeon uses the special Visu max femtosecond laser to create a small piece or bit of lens-like tissue inside the cornea. This type of eye, LASIK, is used for very weak(lazy) eyes with thin corneas. Moreover, the suitable candidates for this surgery have had stable glasses for at least 2 years.


Femto LASIK vs. Eye LASIK: Which One Is Better?

In addition to being comfortable for patients (due to not using a surgical blade) and not causing pain, the benefits of Femto Lasik include:

  1. Predictability of corneal flap thickness
  2. Reducing the risk of cornea loss during surgery
  3. Reducing the risk of astigmatism after LASIK

But keep in mind that your eye specialists must make the final decision about the proper eye Lasik technique.

Eye LASIK surgeries: Which One Is the Best?

With all the explanations that have been mentioned, the choice of eye surgery method should be made by your ophthalmologist. All these eye surgeries are outpatient, and the maximum time of the whole operation is 15 to 20 minutes. This procedure is recommended for people older than 18-19 years, provided their eyesight has remained constant during the past year.

CarefulTrip is one of the best health agencies with skilled and experienced eye specialists and applies suitable eye laser treatment for patients in Iran. CarefulTrip’s competent auxiliary and expert doctors have broken the ground by conducting many successful operations.


What Is the Best Innovation in Lasik Technology?

Eye Lasik surgery is the most popular treatment and undoubtedly helps you change perceptions of eye surgery. But Femto Smile (ReLex Smile: Small incision lenticule extraction) goes beyond this area and takes us further.


While in the past, the traditional Lasik surgeries required the recreation of a flap or removing an area of the cornea, The ReLex SMILE takes a different approach. As if it isn’t enough, Femto-Smile has a whole host of other advantages that prove just how revolutionary this eye treatment technique is:

  • It has a reduced recovery time,
  • It offers safety and comfort to patients,
  • It increases suitability because of the invasive nature of this technique.

To Wrap Things Up

So far, we’ve explained all eye Lasik techniques and technologies. In the evolution of refractive laser techniques, surgeons have always wished to invent closed intracorneal surgery and prevent corneal surface disturbance and flap creation. Vision correction with a Femto-Smile laser is a step in the right direction that makes the correction of refractive errors safer and more effective.

But remember that the final decision on how to perform LASIK eye surgery is the responsibility of the specialist doctor. CarefulTrip has expert eye surgeons and high eye standards for eye Lasik, Lasek, and other eye operations. Besides, it offers patient support services in Iran.
