How Does
INTRACOR Work?
Taking only 20 seconds to perform, the INTRACOR procedure is a gentle, effective* and fast laser treatment. The treatment not only treats your near vision, but also maintains good vision at all other distances, intermediate and distance vision.^
The INTRACOR procedure uses a high-tech laser system called the TECHNOLAS Femtosecond Workstation which is made by a German company called Technolas Perfect Vision GmbH.
The entire procedure is performed without making a single surgical incision through the surfaces of the cornea as the laser is targeted to only work within the cornea, in an area called the stroma.
Presbyopia is corrected by a very gentle all-laser process which accurately adjusts the central shape of the cornea, the front of the eye, to bring near objects into focus.
The INTRACOR procedure uses the laser to make a series of precise, microscopic concentric ring patterns in the stroma which result in a minor alteration to the corneal curvature to compensate for the presbyopia.
Unlike conventional laser corrections, the INTRACOR procedure maintains the natural shape of the eye during the procedure to provide a more personalised and accurate treatment.
The whole procedure is over in just 20 seconds.
INTRACOR successfully reshapes the cornea and redistributes the biomechanical forces necessary for the correction of presbyopia, with the corneal surface being flattened or steepened according to the applied pattern of stromal ablations.
The cut design and stromal depth algorithm depend on the degree of refractive error to be corrected.
Because it is purely intrastromal, there is no incision of the epithelium, endothelium, or Bowman’s or Descemet’s membrane, ensuring the safety of the INTRACOR procedure, with excellent healing and minimal risk of infection.
To ensure eye fixation with minimal biomechanical impact for a high level of predictability, a curved interface is used between the eye and the femtosecond laser.
This has the advantage of not modifying the shape of the cornea or increasing intraocular pressure (IOP) due to flattening of the cornea, further improving accuracy in both the anterior and posterior parts of the cornea.
