Purpose:
To compare differences in intraocular lens (IOL) decentration, tilt and anterior chamber depth (ACD) using Pentacam-Scheimpflug System images in eyes having phacoemulsification with implantation of 1 of 3 types of IOLs.
Methods:
This study comprised 117 cataractous eyes of 109 patients having phacoemulsification and IOL implantation. The eyes were randomized into 3 groups based on IOL type. The degree of IOL decentration, tilt and ACD was measured using Oculus Pentacam System 1 day and 1, 3, 6 and 12 months after surgery.
Results:
There was no significant change during the 12 months follow-up period in decentration or tilt in each group (P > 0.05). There was no significant difference among the groups in IOL decentration or tilt at any time point (P > 0.05). The ACD did not change after surgery in the Acrysof SA60AT group (P > 0.05) but showed significant shallowing in the Tecnis Z9001 group and the Sensar AR40e group (P < 0.05). There was significant difference among the groups in ACD only at 1 day after surgery (P < 0.05).
Conclusions:
The IOL stability in eyes that received a 1-piece Acrysof SA60AT IOL with flexible haptics was better than the results with normal capsular bag IOL implantation and an intact continuous curvilinear capsulorhexis that received a 3-piece IOL with rigid haptics.
