Abstract Details



Purpose:

Postoperative evaluation of the optimized laser assisted endothelial keratoplasty (EK) outcomes. The donor cornea thickness is determined by OCT in the surgery room. A decreasing thickness of the endothelial layer is proposed.

Setting:

Ophthalmic Department, Misericordia and Dolce Hospital, Prato, Italy

Methods:

Intraoperatory OCT is performed in donor cornea to exactly determine its thickness. By the use of the femtosecond laser (iFS150TM, Abbott Medical Optics -AMO, Santa Ana, CA, USA) an endothelial flap of a predetermined thickness is trephined in the donor cornea, and the thickness is decreased to a 70 micrometers thick flap. 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 12 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.

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.
