Long-term results of out-of-the-bag intraocular lens implantation.
OBJECTIVE
To evaluate long-term results of out-of-the-bag intraocular lens (IOL) implantation.


METHODS
Department of Ophthalmology, Tenri Yorozu Hospital, Nara, Japan.


METHODS
This study comprised 22 patients, 13 women and 9 men, who had cataract surgery by phacoemulsification and out-of-the-bag IOL implantation because of a posterior lens capsule rupture. Sixteen patients had in-the-bag IOL implantation in the fellow eye, and these eyes were used as a control group. The IOL's position was determined by ultrasound biomicroscopy (UBM). Anterior chamber flare counts were measured by a laser flare meter. The corneal endothelium was observed by specular microscopy.


RESULTS
Mean follow-up after cataract surgery was 35 months +/- 22 (SD). The UBM revealed that in the 19 eyes with sulcus-to-sulcus IOL fixation, the optics touched the iris. In 3 eyes, 1 haptic was fixated at the sulcus and the other at the ciliary body. In 2 of these eyes, the optics did not touch the iris. Anterior chamber flare counts in eyes with sulcus-to-sulcus IOL fixation were significantly higher than in eyes with in-the-bag or sulcus-to-ciliary-body fixation (P < .05). There were no statistical differences in corneal endothelial cell counts based on haptic placement.


CONCLUSIONS
Rubbing between the IOL optic and iris seems to contribute to the high flare counts in eyes with a sulcus-to-sulcus IOL fixation. A larger haptic angle may be needed to prevent contact between the iris and IOL optic in such cases.
