LASIK (Laser in Situ Keratomileusis) is the most commonly performed type of surgery for vision correction. LASIK is the most common choice of surgeons due to its high accuracy, excellent and long-term stable postoperative results, the complete absence of pain (both during the surgery and in the postoperative period) and a very rare occurrence of complications.
LASIK procedure is a two-step operation. The first step is the forming of the flap (flap on the cornea), and the second is the remodeling of corneal surface using excimer laser. The flap on the cornea can be formed in two ways:
- With mechanical microkeratome (knife, LASIK with microkeratome)
- With femtosecond laser
Femto – LASIK (Synonyms: ALL – Laser LASIK, Bladeless LASIK, iLASIK, Z-LASIK).
Indications for surgery are diopter values from -10.0 to +6.0, and up to ± 5.0 cylinders of astigmatism. This type of LASIK method is fully automated and laser-controlled, without using the knife blade. Femtosecond lasers have been in use since 2001 and they have primarily presented a new step forward in the safety of LASIK surgery. Today, the surgeries in our Hospital are performed exclusively on IntraLase femtosecond laser, which is also the most commonly used femtosecond laser in the world.
Due to the precision of the incision, the flaps of the cornea (the lids on the cornea) have a more regular shape and more predictable thickness compared to flaps made by microkeratome. Therefore, the advantage of such method is of particular importance in higher diopter values, astigmatism and thinner corneas It also reduces the possibility of occurrence of dry eye and enables better healing.
LASIK with microkeratome (standard LASIK)
This is the first developed LASIK method which, besides good technology, also needs an experienced hand of a surgeon to form the flap (the lenticule on the cornea) with the help of microkeratome. Microkeratome is an automated electric knife used for the forming of the flap on the cornea. In the last 25 years the quality, speed, precision and efficiency of mechanical microkeratome has been constantly improving, which led to a significant increase in safety and precision of the surgery. Last generations of microkeratome that we use in our clinic allow very precise forming of flap on the cornea, regular edges and predetermined thickness and shape. The procedure lasts only a few minutes and does not create any discomfort to the patient.
