The flap describes a very thin corneal lamella prepared in the LASIK method. The flap is prepared using a femtosecond laser or a microkeratome to reach the cornea’s deeper layers. The individual tissue ablation is carried out there, depending on the ametropia. This explanation gives you understanding of what is the LASIK flap.
Treatment with the femtosecond laser replaced the conventional micrometer a few years ago. Cutting the cornea with a laser offers decisive advantages:
- Flap preparation with Femto laser
- smooth, even corneal flaps
- thinner flaps, less tissue removal
- more precise and safe method
- painless method, “gentle Lasik”
- a gentle, gentler method
- faster vision rehabilitation
- shaped contact glass
- no incorrect cuts during the operation
- no black-out of the eye
- no interruption of the retinal blood flow
- Flap preparation with a microkeratome
- irregularly shaped corneal flaps
- more stress on the cornea due to thicker flaps
- unsafe method, deviations in the flap thickness
- uncomfortable to painful
- increased exposure to the eye from microscopic knives
- prolonged side effects such as dry eye
- Suction ring
- Incorrect cuts during the operation
- a possible black-out of the eye
- Interruption of the retinal blood flow is possible
After an eye laser treatment, the flap is folded back into its original position and protects the wound like an endogenous plaster. This has the great advantage that the patient can see very well just a few hours after the ametropia correction and does not feel any restrictions in everyday life.
The Advantages Of LASIK And Femto-LASIK
The LASIK method for correcting visual defects has been used since 1990 and is now considered the most widely used method in laser surgery. The process has been scientifically recognized since 1999. Here are some of the advantages of Lasik and Femto-Lasik:
- All visual defects can be corrected: nearsightedness, farsightedness, astigmatism, and, thanks to special profiles, even presbyopia.
- Eyesight development after the treatment: the patient can return to everyday life just hours afterward.
- It doesn’t take time to treat
- The corrections are very easy, so this treatment method is exact
The disadvantages of lenticle extraction:
- The generated lenticular can shift
- During the flap generation, the corneal nerves are severed, leading to increased dry eyes
Are There Any Risks In Lasik Surgery?
For patients who pass the pre-surgical exams but who are also at the minimum age to perform this intervention, myopia surgery presents very low risks during and after the procedure. Of course, as it is a surgery, it is impossible to zero the risks of a problem occurring during the procedure. Still, they are relatively low when the patient meets all the prerequisites for this intervention.
Suppose you have problems with your level of myopia but are not yet old enough to perform this surgery safely. In that case, it is essential to understand the importance of waiting for the right time to count on the help of this intervention in your quality of life.
