Femto LASIK
Femto LASIK is a form of LASIK(Laser-Assisted-In-Situ-Keratomileusis) surgery performed using a femtosecond laser for treating refractive issues. In the procedure, the eye’s top layer is folded back to access and recontour the tissue beneath. The cornea gets reshaped during the procedure so that the light that passes through the cornea falls correctly at the back of the eye, resulting in proper vision.
In LASIK, the doctor cuts off a slice of tissue which results in a flap being formed at the front of the eye. Through this flap the doctor can access the inner corneal tissues with the aid of an excimer laser.
In Femto LASIK procedure, the flap is created using a femtosecond laser.This near-infrared laser is short-pulsed. It enables high intensity during extremely short pulse durations- within just a few femtoseconds, in fact. This property enables extremely precise incisions to be made in the corneal tissue but without affecting the tissue in the surroundings in any way.
Once the flap is folded back, the eye can be treated with an excimer laser to correct any refractive error. Only the tissue that needs to be removed gets ablated with the laser while the surrounding tissue remains intact.
Once this is done, the eye is covered with a bandage lens. This is left on till the epithelium grows again- typically, this takes a few days. However, complete recovery of vision could take about a month or in some cases, even longer. Compared to some other laser surgical methods, the recovery time is longer for PRK.
An exceptional laser system which provides accuracy, safety and a high speed in performing the procedure.
Combining 6D eye tracking technology with 750 Hz repetition rate, the SCHWIND AMARIS 750S enables high speed of use and facilitates extremely accurate laser procedures to perform refractive and therapeutic corneal surgery. It comes equipped with a sharp 0.54 mm laser spot which yields incredible accuracy. Meanwhile, its smartly designed swiveling laser arm affords high levels of convenience for both the medical professional and also the patient undergoing the procedure.
This laser system is versatile enough to be used in all typical laser treatments, which include SCHWIND’s SmartSurface: a touch-free system that provides quicker healing and also shorter recovery time compared with conventional surface treatments. Thanks to the SCHWIND CAM treatment planning, a wide array of applications are now covered by products under AMARIS.
The exceptionally capable 6D eye tracker is a proprietary tool developed by SCHWIND and which forms a part of this laser system. It helps improve the treatment success with its extreme accuracy. Capturing every movement of the eye(both static and dynamic) in the course of the procedure, it is connected to the diagnostic systems of SCHWIND, thereby delivering superior results.
The eye movement dimensions given below are accurately determined and compensated for thanks to this:
Once a change in the pupil size is perceived, the laser is adjusted accordingly. Along with the 6D eye tracking system, this automatic feature helps the doctor ensure that the precise centering occurs throughout the surgery.
750 Hz pulse rate: For exceptional speedThanks to an exceptionally fast repetition rate and the extremely short ablation time of 1.5 seconds per dioptre* patients can enjoy enhanced comfort while the procedure becomes more safe. Also, the chances of corneal dehydration are reduced. The system also brings down the duration for which a patient would need to stare at the green light.

The key difference between the two methods is in the manner in which the flap is created on the cornea. In conventional LASIK, a mechanical device called microkeratome is used for this. But in Femto LASIK, a laser is used for the same. Compared to using a mechanical device, laser affords a far more accurate and predictable way to create the flap.
Not every patient would gain 20/20 vision after having a LASIK procedure. At the same time, a global review of the procedure conducted in 2009 shows that over 95% of patients who underwent LASIK from 1995 to 2003 were satisfied with the result of the procedure.
The procedure itself takes only about five minutes to complete. The patient would be able to go back to their regular routine in a day or two. The complete recovery time would differ from patient to patient. Nonetheless, the flap becomes stable in just a few days. As for the patient’s vision, it would take a few days to stabilise since surgery. Usually, doctors would ask the patient to come in for a follow-up exam on the day after the procedure, and a month since the procedure.
