Assessment

Primary outcomes

Images taken before and after removal of OVD are captured from the recorded video. A reference line is determined by connecting two critical details, and another line is determined by joining two details on the IOL. The angle at intersection of these two lines is measured, and the difference in the angles before and after OVD removal was defined as the angle of rotation.
The angle of rotation during OVD removal using the current technique and conventional technique are compared. The angle of rotation using conventional technique is published in previous study.

The conventional surgical technique using OVD, IOL is inserted into capsular bag filled with OVD, adjust the position of the IOL, and then remove the OVD. In this method, the IOL rotates during removal of the OVD and needs to be readjusted.
With the new technique, after inserting of toric IOL, OVD is injected above the IOL and BSS is injected under the OVD. IOL is rotated to the final position and the OVD is removed.
