Refractive surgery to correct vision defects

Refractive surgery to correct vision defects such as myopia, hyperopia and astigmatism is currently the most appropriate and effective technique to modify the anatomy of the eye. In this post we talk about its advantages.

What is refractive surgery?

The FEMTOLASIK technique is a type of FEMTOSEGUNDO laser-assisted eye surgery for cutting the corneal flap. With more than 5 million operations performed worldwide, it is the most modern and safest technique available today. In recent years, laser eye surgery to remove nearsightedness, farsightedness and/or astigmatism has been revolutionized.

Why undergo eye surgery with the FEMTOSEGUNDO technique at OMIQ?

Because, as in other techniques, we are not only one of the few clinics that have the machinery and experience, but our results are 100% satisfactory.

The FEMTOSEGUNDO laser is by far the biggest revolution in eye surgery in recent years. This is because it has succeeded in replacing the cut that was produced manually on the cornea with a much more precise one, ideal for patients with a very thin, very curved or, on the contrary, excessively flat cornea.

What is the difference between LASIK surgery with a blade and LASIK surgery with a FEMTSECOND LASER?


It consists of placing a ring that will exert pressure on the eye to prevent it from moving and then making a cut in the superficial tissue of the cornea with a blade (microkeratome). Subsequently, the layer is lifted (FLAP). Once finished, the flap is placed again so that it adapts to the cornea.


The Femtolasik technique follows a process very similar to traditional Lasik. However, in this type of intervention, the microkeratome is replaced by a precise femtosecond laser. Using infrared pulses, this laser is able to create small CO2 bubbles that separate the corneal tissue without the need for cutting. This way they create the flap in a much more precise, safe and natural way. Then, as in Lasik, the excimer laser treatment is applied to correct the refractive error and the flap is repositioned over the cornea.

The use of the Femtosecond laser minimizes the chances of surgical complications. In addition to guaranteeing better results and greater safety during surgery.

Difference between refractive surgery with microkeratome (Lasik) or Femtosecond Laser.

  1. In the microkeratome, a clean cut is made, while in the case of the laser, no cut is made, but the tissues are separated. This helps make recovery much faster.
  2. The “cut” made by the laser is accurate because it is controlled by software that will have the exact data provided by the ophthalmologist. If the cut is performed manually (with a knife), it depends on the surgeon’s skill. In this case there is a 5% risk that it will not be accurate.
  3. The laser poses less risk to the cornea.
  4. The accuracy of the laser makes it possible to operate on thinner corneas.
  5. As a consequence, the results with the laser are more precise and better.
  6. The Femtosecond Laser is currently considered the most precise in intraocular surgery.

In conclusion, we can say that the Femtosecond Laser represents better results, a faster recovery time and one of the safest techniques available today.
