**3. Effects of incision on capsulorhexis**

An ideal surgical incision is the fundamental prerequisite for successful capsulorhexis. In Europe and America, a temporal incision is preferred, while in Asia it is mostly performed at an 11 o' clock position. Regardless of the orientation, when the incision is made, the direction of the tunnel knife should be along the meridian of the cornea, as shown in **Figure 17**.

A meridional incision does not limit the movement of capsular forceps, which ensures that the anterior opening is centered and perfectly round. When the incision deviates from the meridian, the boundaries of the inner incision will limit the track for the capsulorhexis forceps as shown in **Figure 18**.

To avoid wrist dangling, the surgeon's hands or wrists should rest steadily against the patient's forehead. This will allow the surgeon's hands to move synchronously with the patient's head if the they move head abruptly. The angle at which the hands
