Objective/Purpose
The posterior capsular wrinkle can sometimes be observed after intraocular lens (IOL) implantation. However, mechanisms of the wrinkles are not well known. In this study, we analyzed the relationship between posterior capsular wrinkle and position of IOL.

Materials/Patients
Subjects comprised 30 eyes that underwent phacoemulsification with IOL (HOYA, PY-60AD). The mean age of patients is 75.3±9.4.

Methods
Images were taken using an EAS-1000 (NIDEK) after 1 week, 1, 3, 6 months and 1 year postoperatively. And the patients were divided into a wrinkle group (the wrinkle was recognized in posterior capsule) and a no-wrinkle group. In the wrinkle group, the relationship between the position of wrinkle and the position of optic-haptic junctions were analyzed. And also the axial length were compared in two groups.

Results and Conclusion
The wrinkle were observed in 11 eyes (36.7%) and the wrinkles were appeared immediately after surgery and were not decreased for 1 year postoperatively. In the wrinkle group, the direction of wrinkle were placed at an angle of 55.4±3.6 degree from optic-haptic junctions regularly. The axial length were 23.47±1.03 mm in the wrinkle group and 24.50±1.24 mm in the no-wrinkle group. There were statistically significance in two groups (P = 0.02).

The wrinkle placed to direction of vertex in haptics. And the wrinkle often occurs in short axial length eyes that have small lens capsules.
