Procedure in 3 steps:
1. Preparation of the cornea
With a precision knife, an incision is placed to create a thin flap of the cornea (0.16 mm). If a laser is used instead of the knife, the procedure is called Intra-LASIK.
The corneal flap is flapped back like a book cover.
2. Application of the laser
The exposed lower corneal tissue is reshaped according to the refractive error. Nearsightedness is corrected by flattening the center of the corneal tissue. For the correction of farsightedness, the ablation takes place in a circle around the periphery of the corneal center. If, in addition to nearsightedness or farsightedness, astigmatism is present, it is corrected by ablation in a manner that the cornea regains a ball-like shape.
3. Closing of the wound
The corneal flap is repositioned back onto the stromal bed. It sticks to the corneal tissue on its own and acts like a band-aid.
