Abstract
Purpose To examine the centration and visual outcomes after cataract surgery using the bag-in-the-lens (BIL) implantation technique. Setting University Hospital Antwerp, Department of Ophthalmology, Edegem, Belgium. Methods This study comprised 180 eyes of 125 patients who had cataract surgery with implantation of the BIL intraocular lens (IOL) between March 2002 and September 2005. Postoperative data at 5 weeks, 6 months, and 1 year were evaluated. The geometric center of the IOL, measured on a red reflex slitlamp photograph, was compared with the geometric center of the pupil and the limbus. Results The mean decentration compared with the limbus was 0.304 mm ± 0.17 (SD) at a mean angle of −24.9 ± 113.3 degrees. Compared with the dilated pupil, the mean deviation was 0.256 ± 0.15 mm at a mean angle of −5.2 ± 119.0 degrees. The amount of decentration was stable during the postoperative follow-up period. There was no correlation between the amount of decentration and the visual outcomes (pupil: r = −0.07, P = .494; limbus: r = 0.11, P = .304). Conclusions Surgeon-controlled BIL centration was predictable 5 weeks and unchanged 6 months and 1 year postoperatively. It can therefore be concluded that capsular bag healing has no influence on BIL IOL centration over time.
