The patient is an actor in the surgery, without him and his desire to take part, it would not be possible to operate on him. In order not to feel anything, he has drops that will numb the surface of his eye. Medical staff need their cooperation to look at lights and direct their gaze.

Laser operation of the eye with LASIK technology, which consists of cutting a corneal flap with the “Femtosecond” laser and “Excimer” laser treatment to rectify the radii of curvature of the cornea in order to correct visual defects . Here, the first phase of creation of the shutter has been carried out. The surgeon looks for the edge to lift it. When he has lifted the flap, he will apply a laser treatment to resculpt the cornea in order to erase the visual defects. Nyon, October 16, 2024. — © Christophe Chammartin / Le Temps
This is the moment of “docking”, i.e. the coming into contact between the cornea and the laser applanation cone. This is an important moment in centering the corneal flap cutout for a LASIK type laser operation. The red point is the patient’s fixation point which allows their visual axis to be materialized.

During laser eye surgery, technology assists the surgeon. Iris recognition recognizes the patient and the eye to be operated on, and notably positions the treatment in the same place as the measurement. Vison Future Clinic, Nyon, October 16, 2024. — © Christophe Chammartin / Le Temps
The choice of one technique or another depends on the assessment carried out with the patient before the operation and the skills of the surgeons. Nyon, October 16, 2024. — © Christophe Chammartin / Le Temps
The sterile transparent film makes it possible to create aseptic conditions in a given environment. Its aim is to maintain a germ-free state to avoid infections or contamination, particularly in medical, surgical or food contexts. As the interventions are carried out in the operating room, the risks of infection are minimized. Nyon, October 16, 2024. — © Christophe Chammartin / Le Temps
Phase of laser treatment during which the blue dots represent the interaction between the laser and the cornea. The supply of light energy sublimates the matter, which passes from a solid state to a gaseous state without passing through the liquid state. The laser removes material where it is necessary: in the center for myopes, at the periphery for hyperopias and vertically or horizontally for astigmatics. For presbyopes, it is an algorithm that combines several parameters. Nyon, October 16, 2024. — © Christophe Chammartin / Le Temps
PKR and Femto-Lasik laser intervention techniques to correct vision problems were developed in the 1990s. In recent years, they seem to be gaining popularity. Nyon, October 16, 2024. — © Christophe Chammartin / Le Temps
