Purpose:
To compare differences in decentration and tilt between a silicone multifocal and an acrylic intraocular lens (IOL) by evaluating postoperative changes.
Setting:
Department of Ophthalmology, College of Medicine, The Catholic University of Korea, Seoul, Korea.
Methods:
Forty eyes of 20 patients with IOL implantation were randomized into 2 groups according to IOL type: 3-piece silicone multifocal IOL or 3-piece acrylic IOL. All lenses were implanted in the capsular bag through a clear corneal incision after continuous curvilinear capsulorhexis and phacoemulsification. The amount of the decentration and the degree of the tilt of each IOL were measured using the EAS-1000 anterior eye segment analysis system 1 day and 1 and 2 months after surgery.
Results:
No significant difference in decentration and tilt was found among the 3 follow-ups or between lens types.
Conclusion:
Neither IOL decentration nor tilt showed significant progression up to 2 months in eyes with a silicone multifocal or acrylic IOL when the IOLs were placed properly in the capsular bag. The amount of decentration and tilt was similar between lens types.
