The femtosmile eye technique or the Relax Smile operation (ReLEx SMIILE) is the latest generation of surgeries to correct refractive errors and remove glasses, which is known as the least invasive treatment method for correcting myopia and astigmatism. The most important advantage of the Femtosmile procedure is that it is performed without any exfoliation of the corneal surface.

Femtosmile operation is the best choice for all myopic patients with astigmatism (if prescribed by an ophthalmologist). In this procedure, a femtosecond laser (one of the fastest and newest ophthalmic lasers) is used for cutting, due to the minimal amount of energy entering the cornea, the cornea recovers and heals faster. The point that should be mentioned here is that in this operation, vision improvement will be achieved gradually (between one and six weeks), which means that the patient must have enough patience to obtain the final and optimal vision, because sometimes one has to wait up to two months to reach the highest level of vision.

What is the procedure of femtosmile (Relax Smile)?

Relax technique is used in Femtosmile method. In this technique, laser light is used for very precise cuts. In fact, in the Femto Smile method, laser light is used to create a very small incision similar to the design of a smile on the cornea, due to its high penetrating power, as well as its ability to be adjusted in very precise cuts.

In Femtosmile, the cutting of the corneal surface is not done with a surgical blade like the eye LASIK operation. In this method of laser operation, the surgeon uses the special Visu max femto second laser to create a small piece or bit of lens-like tissue inside the cornea. Then, a small crack in the shape of a smile is created on the cornea by a femtosecond laser. Then, through this very small gap, that tiny refractive lens is taken out.

This method is actually taking out the lens from the small smile-like crack in the cornea. This type of LASIK is used for high eye scores and thin corneas.

What are the benefits of femtosmile eye surgery?

This surgical method has many advantages, the most important of which is that more people are accepted for this type of treatment. Femtosmile is a type of minimally invasive laser eye surgery, which does not lead to flap complications since no flap is created during the smile procedure.

The process of performing this type of surgery is very fast, so it usually takes about 15-20 minutes for both eyes. Patients recover quickly after Smile eye surgery, and the eye usually recovers about 80% in the first few hours and reaches the maximum recovery rate within a few weeks.

Femtosmile is better or Lasak?

In the Lasak method, refractive problems of the eye are solved in a wider range. That is, hyperopia, myopia and astigmatism problems are corrected, while femtosmile is only used for myopia. But if the two methods are compared for myopia, it can be clearly said that Smile is much more suitable than LASIK because it solves severe myopia problems up to 10 diopters and has a shorter recovery period than LASIK. The Smile operation does not have a flap, and problems and complications do not arise after the flap, but in the LASIK operation, since a flap is created, you must follow special care.

What are the disadvantages of femtosmile?

Femtosmile can be used for myopia and myopic astigmatism problems, but it cannot be used to correct farsightedness.

The cost of performing Femto Smile operation is higher than other laser surgeries.

Unlike LASIK, Femto Smile currently cannot be used to treat farsightedness.

Vision improvement after Femto Smile takes a little longer than LASIK.

Conclusion

Femtosmile method is the latest laser surgery method that can be performed for a wide range of people who suffer from eye problems. In this method, unlike other methods, the length of the cut is very small and there is no need for stitches after the operation. Therefore, the recovery period in this method will be very short.
