The FemtoLASIK method is a superb modern technology of removal dioptres using two latest lasers: femtosecond laser iFS and excimer laser VISX STAR S4 IR, both from Johnson & Johnson, an American company.
To begin with, the ultra-fast femtosecond laser is used (using the principle of photo-disruption) to create a thin lamella on the cornea. The Laser beam is focused into one single point where energy is concentrated, and the tissue of the cornea immediately turns to gas (it literally evaporates). In this way, miniscule bubbles are formed and these too further help in the process of separating the tissue. The lamella created in this way is more perfect and smoother then when an oscillating blade is used.
The lamella in the cornea is then lifted to the side and using the effect of the excimer laser, the cornea is re-shaped into the required shape and curvature as a result of which the dioptre error is corrected. Once done, the lamella of the cornea is returned to its original position and the surgery is completed.

Advantages of FemtoLASIK over LASIK
-
We use femtolaser to create the lamella in the cornea. As such we do not use an oscillating (microkeratome), making the procedure sharp tool-free
-
Greater precision in forming the lamella (predictability).
-
Reduced risk of formation of a defect in the epithelium of the cornea.
-
Reduced risk of induced astigmatism.
-
Creating a thinner lamella thus enabling the removal of more dioptres.
-
Possibility of shaping the edge of the lamella using a software and thus ensuring its perfect re-attachment once it is returned to its original position.
Who is this method suitable for?
FemtoLASIK is a good choice for all those patients where individualised procedure is not required or where it is not possible to perform an individualised procedure. We recommend this method specifically to patients with the following:
- short-sightedness (lower, medium as well as higher)
- far-sightedness (from +4,0 dioptres on)
- relatively symmetrical astigmatism (up to +/−4,5 dioptres max.)
- uncomplicated refractive error without significant asymmetry
