简要总结
The purpose of this study is to compare two cataract surgical technique variations for removing the nucleus of the lens (central part of the lens) in terms of damage to the inner layer of the cornea which is called the endothelium. One variation uses more ultrasound energy and the other more mechanical force to break up the nucleus.
