No matter how ready you are for a life without spectacles or contact lenses, the decision to undergo Laser Vision Correction is a big one.
Your eyes are most important, and you want to make sure that the procedure you undergo offers you the maximum safety, precision, and comfort.
For all those who are fed up with the tedious rituals of the severely near-sighted – wearing contact lenses, treating dry eyes and blind fumbling for glasses at night, latest technology brings reasons to smile by introducing a much safer procedure which is flapless.
ReLEx Smile or Refractive Lenticule Extraction is one of a quick and ablation free techniques that is boon especially for those who have thin or irregular cornea.
According to Dr. Mahipal S Sachdev, Chairman – Centre for Sight ”Thousands of people who cannot get Lasik due to buttonhole irregular corneal curvature can now have a laser vision correction procedure which is not only 100% blade free, but also allows the luxury of no corneal flap creation, and which offers a pain free treatment in few minutes. 15% of all patients who go seeking laser eye surgery are found to have corneas that are too thin or too dry. ReLEx can help patients even with thinner corneas and very high prescriptions of up to -14 in some cases.”
Unlike LASIK, which uses two lasers and vaporizes the corneal tissue to correct vision, ReLEx uses only one laser for the entire procedure.
Instead of vaporizing the unwanted tissue, the new generation laser used in ReLEx simply cuts out a lens-shaped piece of corneal tissue to correct myopia.
The tissue is extracted through a keyhole incision.
This means more accurate vision correction and less discomfort during and after surgery. ReLEx is a step superior to the No Blade approach of Femto-LASIK.
In Femto-LASIK, a laser is used to create the corneal flap, which is then folded back by the surgeon to perform the LASIK procedure.
While Femto-LASIK or No Blade LASIK is superior to the more traditional method of microkeratome blade LASIK, it still means that a corneal flap needs to be created in the eye.
This procedure has a 100 percent success rate. It is also more accurate than LASIK, which is especially beneficial for those with higher degrees of myopia, between 500 and 1,000 degrees.
This is currently the most advanced procedure available. And it only takes 30 seconds to perform the correction as this laser is extremely fast and uses very low energy, so there is less discomfort for patients.
ReLEx also feels more comfortable for the patient because the suction on the eye during the treatment is gentler.
Advantages of the ReLEx SMILE
The ReLEx SMILE method gives the surgeon many advantages over the conventional LASIK treatment. These include:
- No Flap to Displace: Since there is no flap, there is no risk of flap displacements and flap-related complications to occur.
- Less Dry Eye: Because of the tiny incision, there is less cutting of corneal nerves, leading to less dry eye and improved corneal sensitivity after the procedure.
- Better Corneal Biomechanics: Since the lenticule is removed from a small incision, the corneal biomechanical strength is less reduced after ReLEx SMILE than with other techniques.
- Much More Precision and Stability: ReLEx SMILE does not involve using an excimer laser at all, only a femtosecond laser. The total energy introduced by the laser into the eye is up to 10 times less than an excimer laser. So inflammation is less, and there is more stability in the result.
While an excimer laser is dependent on atmospheric humidity and other conditions, the femtosecond laser is much more robust.
The result is a much more precise treatment. This ensures that the patient has a more comfortable and better visual quality after the ReLEx SMILE method.
