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.
Ophthalmic Department, Misericordia and Dolce Hospital, Prato, Italy
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.
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.
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.
