Assessment of Capsular Bag–Fixated and Ciliary Sulcus–Fixated IOL Centration After Supplementary IOL Implantation
To assess intraocular lens (IOL) centration (capsular bag and sulcus) in cases of primary (Duet) or secondary implantation of a sulcus-fixated supplementary IOL.
In this retrospective image analysis study, 44 eyes of 40 patients who were implanted with a sulcus-fixated supplementary IOL, Sulcoflex (Rayner Intraocular Lenses Limited) were evaluated. The mean follow-up was 27 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.
The mean age of the patients was 63 ± 14.8 years (range 37 – 85 years and 45% were male, with 55% being female. There were no intra- or postoperative complications in any cases. The mean decentration of the capsular bag-fixated IOL was 0.28 mm (± 0.16 SEM) when compared with the limbus and 0.29 mm (± 0.2 SEM) when compared with the dilated pupil. The mean decentration of the sulcus-fixated IOL was 0.23 mm ( ± 0.15 SEM) when compared with the limbus and 0.22 mm ( ± 0.14 SEM) when compared with the dilated pupil. There was no significant difference in decentration between the two IOLs.
Both capsular bag-fixated and ciliary sulcus-fixated IOLs showed good centration in eyes implantated with a sulcus-fixated supplementary IOL. Furthermore, the absence of intra- or postoperative complications in all cases confirms the safety of the Sulcoflex Supplementary IOL.
