Capsular bag-fixated and ciliary sulcus-fixated intraocular lens centration after supplementary intraocular lens...

To assess capsular bag and sulcus intraocular lens (IOL) centration in eyes that had implantation of a sulcus-fixated supplementary IOL anterior to a preexisting capsular bag IOL.

Academic Teaching Hospital of St. John, Vienna, Austria.

Retrospective case series.

A sulcus-fixated supplementary IOL (Sulcoflex) was implanted anterior to a preexisting capsular bag IOL. The geometric center of preexisting capsular bag IOLs and newly implanted sulcus-fixated IOLs was evaluated at least 12 months postoperatively and in relation to the geometric center of the pupil and limbus.

The study comprised 48 eyes of 43 patients with a mean follow-up of 25 months (range 12 to 84 months). The mean decentration of the capsular bag-fixated IOL was 0.29 mm ± 0.02 (SEM) when compared with the limbus and 0.29 ± 0.03 mm when compared with the dilated pupil. The mean decentration of the sulcus-fixated IOL was 0.23 ± 0.02 mm in relation to the limbus and 0.22 ± 0.02 mm when in relation to the dilated pupil. Sulcus-fixated supplementary IOLs showed significantly better centration than bag-fixated IOLs when compared with the limbus and with the pupil (both P = .03, paired t test).

Implantation of a sulcus-fixated supplementary IOL resulted in good centration of capsular bag-fixated IOLs and ciliary sulcus-fixated IOLs. However, ciliary sulcus-fixated IOLs achieved significantly better centration.
