SCHWIND now offers the KPL (Keratoplasty) option for safe and precise corneal transplants. This method is suitable for all patients for whom keratoplasty is indicated: for example for treating deep corneal scars following injuries, corneal dystrophies and advanced keratoconus. No eye suction is required with laser-assisted KPL. With KPL, corneas can be treated up to a maximum depth of 999 micrometres. KPL can be used for penetrating keratoplasty.
With penetrating keratoplasty, the donor and recipient cornea are treated, without contact, using the AMARIS laser system. As a rule, the physician employs special ring masks in order to achieve sharp cornea edges and a perfect fit. Whilst separation of the tissue with the excimer laser takes somewhat longer compared with a femtosecond laser, the results in terms of centration and alignment are considerably more precise. Result: less astigmatism, a more homogeneous cornea and an improved vision outcome.
KPL is part of the PTK-CAM toolbox and module of SCHWIND CAM software. The KPL application requires a separate activation for each AMARIS laser system. Prior to each application, an additional safety message appears to check whether corneal perforation is indeed desired
The PTK-CAM module provides support for therapeutic treatments: both superficial and deep corneal scars and corneal degeneration can be corrected precisely. You can choose between superficial refractive-neutral or deep ablation for keratoplasty. PTK-CAM is based on the method of phototherapeutic keratectomy (PTK).
