Abstract Details


The donor cornea thickness is determined by OCT in the surgery room, in order to perform an ultrathin DSEK (donor layer thickness lower then 90 micrometers).


U.O. Oculistica, Nuovo Ospedale S. Stefano, Prato (Italy)


Intraoperatory OCT is performed in donor cornea to determine its thickness. By the use of the femtosecond laser (iFS150TM, Abbott Medical Optics -AMO, Santa Ana, CA, USA) an ultrathin endothelial flap is prepared; the thickness is in the range 70 - 90 micrometers. Manual stripping of the recipient eye is performed. The donor tissue is positioned in the correct final configuration by performing diode laser (@810 nm, produced by El.En. s.p.a., Calenzano –FI, Italy) welding procedure.


In a 48 months follow up study, it was evidenced that a thin flap having a known and definite thickness enables a good functional recovery and a modest endothelial cells loss. No flap dislocation was observed.


The use of the last generation technologies (intraoperatory OCT, femtosecond laser for trephination, and diode laser for suturing) provides an improvement in EK and a rapid and good visual recovery.
