Abstract Details

Purpose:

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).

Setting:

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

Methods:

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.

Results:

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.

Conclusions:

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.
