Silicone and poly(methyl methacrylate) lens decentration associated with asymmetric capsule shrinkage in rabbits
Purpose:
To determine whether silicone intraocular lenses (IOLs) are readily affected by capsule shrinkage.
Setting:
Department of Ophthalmology, Wakayama Medical College, Wakayama, Japan.
Methods:
A D-shaped incision was made in the anterior capsule of 38 eyes of 20 white rabbits. One of 2 IOL types was implanted in the capsular bag: 3-piece silicone or single-piece all-poly(methyl methacrylate) (PMMA). Twenty-eight eyes were evaluated for IOL rotation and optic decentration.
Results:
The extent of postoperative decentration and rotation observed with the silicone IOLs did not significantly exceed that of the PMMA IOLs.
Conclusions:
Our results, coupled with the advantages of small incision surgery, indicate that a silicone IOL is an effective choice.
