To determine whether silicone intraocular lenses (IOLs) are readily affected by capsule shrinkage.
Department of Ophthalmology, Wakayama Medical College, Wakayama, Japan.
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.
The extent of postoperative decentration and rotation observed with the silicone IOLs did not significantly exceed that of the PMMA IOLs.
Our results, coupled with the advantages of small incision surgery, indicate that a silicone IOL is an effective choice.
