• Femto PK FS200 Description: We are currently using the WaveLight FS200 femto-second laser which has the ability of performing any type of sidecut incisions to a depth of 800 microns and with a maximum diameter of 10mm, thus being able to perform a completely bladeless penetrating keratoplasty. The most popular technique is the zigzag technique both on the donor tissue and on the host tissue, which enables a larger area of contact between graft-host interface and thus the possibility of a stronger adherence of the graft to the host cornea.
