The Zeiss surgical keratometer in cataract surgery

The Zeiss keratometer is easy to use with simple and fast reading. The preoperative keratometry principle is satisfactory by allowing theorically a better control of surgical factors of postoperative astigmatism after cataract surgery. Its major interest appears in surgical training, when one wants to compensate a preoperative astigmatism or when one wishes to avoid secondary suture removal. However, its interest is very variable according to surgical experience.
