Abstract Details

Purpose:

To assess intraocular lens (IOL) centration (capsular bag and sulcus) in cases of primary (Duet) or secondary implantation of a sulcus-fixated supplementary IOL.

Setting:

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

Methods:

In this retrospective image analysis study, 48 eyes of 43 patients who were implanted with a sulcus-fixated supplementary IOL, Sulcoflex (Rayner Intraocular Lenses Limited, UK) were evaluated. The mean follow-up was 25 months. (range 3-84 months) The geometric center of both the capsular bag- and sulcus-fixated IOLs was measured with the image analysis program Adobe Photoshop CS6. This measurement was compared with the geometric center of the pupil and the limbus.

Results:

The mean age of the patients was 63 ± 13.2 years (range 37 – 85 years) and 44% were male, with 56% being female. There were no intra- or postoperative complications in any cases. The mean decentration of the capsular bag-fixated IOL was 0.29 mm (± 0.02 SEM) when compared with the limbus and 0.29 mm (± 0.03 SEM) when compared with the dilated pupil. The mean decentration of the sulcus-fixated IOL was 0.23 mm ( ± 0.02 SEM) when compared with the limbus and 0.22 mm ( ± 0.02 SEM) when compared with the dilated pupil. The sulcus-fixated supplementary IOL showed significant better centration when compared with the limbus (paired t-test, p=0.03) and with the pupil (paired t-test, p=0.03).

Conclusions:

Both capsular bag-fixated and ciliary sulcus-fixated IOLs showed good centration in eyes implanted with a sulcus-fixated supplementary IOL. However, there was a significant better centration of ciliary sulcus fixated IOLs. Furthermore, the absence of intra- or postoperative complications in all cases confirms the safety of the Sulcoflex Supplementary IOL.
