[Focus on the right choice of suitable indications for corneal endothelial transplantation].

Endothelial keratoplasty (EK) demonstrates many advantages over penetrating keratoplasty (PK), which is expected to become an initial surgical choice for the treatment of corneal endothelial dysfunction, instead of PK. However, EK also has the defects in the low density of endothelial cells after surgeries. And the bullous keratopathy in China is mainly caused by intraocular surgeries such as cataract extraction, which was accompanied by a variety of intraocular abnormalities. The complex cases will undoubtedly make the surgeries more difficult, and make endothelial cells density lower after surgeries. It is the most important that a suitable surgical procedure and the indications were selected on the basis of the patients' clinical characteristics. Adoption of some modified EK techniques can reduce postoperative endothelial cell loss, which can improve the successful rate of surgeries.
