What is the femto smile process?
By asking Dr. Muhammad Hantira - Honorary Assistant Professor - Department of Ophthalmology - Umm Al-Qura University - Saudi Arabia, explain to us.
Smile technology is considered the latest in laser refractive error correction operations and includes making a very small incision at one end of the cornea using a femtolizer, and the cornea is calibrated to adjust its heights in different areas, according to the specified measurements and using a femtolizer as well, and the surgeon removes the excess part of the retina after calibration A small meniscus formed, through the small incision that was previously made.
What are the advantages of the femto smile process?
Dr. Hantira explained:
According to the studies conducted on patients who underwent Smile, the same positive results that patients benefit from in LASIK have been observed in terms of visual acuity in myopic patients, without the need to open and separate the outer shell of the cornea.
In addition to a lower risk of some complications associated with LASIK procedures, such as dry eyes, as the Smile operation does not cause dryness in the eyes, because the corneal nerves are not affected.
What are the disadvantages of the femtosmile process?
One of the most important defects and limitations of the SMILE process is that it only treats myopia, unlike LASIK procedures, which treat farsightedness and visual aberration.
It also requires surgeons who are highly experienced and skilled in this specialty, to obtain the best possible results after the operation.
Conditions of the femtosmile process
Dr. Hantereh indicated:
That Smile operation is not considered suitable for every patient, and there are some conditions that must be applied to the patient before performing this type of operation, including:
- The patient must be 22 years of age or over.
- The refractive problem has not changed, from length or shortness, for at least one year.
- That the patient suffers from a shortness of between one to eight degrees without deviation, or a small degree of deviation.
- The absence of any diseases or problems in the cornea.
After the femto smile
Dr. Hantara explained :
- That you will not be able to drive your car yourself, but you must bring an escort with you, and you will have to rest for a full day after the operation.
- The patient may suffer from some blurry vision in the post-operation period, but the vision improves soon.
- The patient must also adhere to the treatments prescribed by the doctor.
- The patient avoids washing his eyes with water a lot.
- You can continue normal activities after two days of the operation.
Femto Smile results
Dr. Hatarta explained:
The SMILE process is relatively recent but the initial data accumulated until the moment has shown its safety and success, and its role as a suitable alternative to other lasers from previous generations.
