Fig. 31. Alcon SN 60 WF in good position with respect to the dilated pupil and the capsule opening. The overlap is approximately 0.5 mm. Greater overlap tends to create a more prominent anterior capsular opacification and a tendency toward capsular contraction. A smaller amount of intended overlap can result in incomplete overlap so that a portion of the IOL is not covered by the anterior capsule remnant. Note the slight irregularity in the lower right quadrant. This is the initiation and finish quadrant where such irregularities are more common. (Courtesy of James A.
