Height scale of an eye during treatment with PTK Cam


PTK-CAM for successful cornea treatments

Effective planning for therapeutic procedures

The SCHWIND CAM PTK-CAM module supports treatments for corneal degeneration, 
dystrophy and erosion, as well as superficial and deep corneal scars. PTK-CAM is based on phototherapeutic keratectomy (PTK) and addresses superficial refractive-neutral ablation, as well as deep ablation for perforating laser-assisted keratoplasty with the KPL option. 

Benefits at a glance

Safe and precise planning of phototherapeutic corneal ablation, 
including penetrating keratoplasty (KPL)

Many options for tissue ablation, depending on the clinical indication

The highest precision through refractive-neutral ablation

  • Overview of height scales of an eye during treatment with PTK Cam

    Examples for different ablation profiles in the PTK-CAM profile

  • Ring height scale of an eye during treatment with PTK Cam

    Circular KPL ablation profile

  • Oval height scale of an eye during treatment with PTK Cam

    Elliptical ablation within 10 mm diameter

Safe corneal transplants with KPL

The KPL (keratoplasty) option provides for safe, precise planning of deep corneal ablation. 

Separation of the tissue with an excimer laser gives more precise results in terms of centring and alignment than does a femtosecond laser. This means less astigmatism, a more homogeneous cornea, and improved vision.

No eye suction is required for laser-assisted KPL. In penetrating keratoplasty, the donor and recipient corneas are treated touch-free with the SCHWIND AMARIS laser. 


Free choice of ablation shape and depth

With PTK-CAM, the surgeon can freely decide how deep to ablate. The module is designed as a toolbox and provides for round, elliptical or individual ablation profiles.


The highest precision

The innovative PTK profile prevents refractive changes like hyperopisation and astigmatism. Ablation is refractive-neutral.

Using “ablation offset” and “pupil offset” simultaneously favours the topographically exact correction of superficial scars. Pupil offset lets the doctor move the ablation to the centre of the topography. Ablation offset allows further shifting of the ablation based on the cornea findings.
