The Effect of Extracapsular Cataract Extraction Using Nucleus Dislocation into Anterior Chamber on the Corneal Endothelium

When the continuous circular capsulorhexis(CCC) is being performed, the nucleus delivery using nucleus dislocation into the anteroir chamber is safer and easier than using conventional “push and pull” method to maintain an intact lens capsule. This method include such procedures that after CCC, the nucleus being freed in the capsular bag by hydrodissection and hydrodelineation, then hooked with a Sinskey hook and drawn out to the anterior chamber by rotation. It may damage the corneal endothelium because of the manipulation in the anterior chamber. To investigate an effect of this method on the corneal endothelium, we performed two months time analysis of changes of the central corneal endothelial cell density (CECD) in two groups-a group with an extracapsular cataract extraction (ECCE) using nucleus dislocation into the anterior chamber and a group with a conventional ECCE.
