Purpose

Evaluation of Tilt and Centration of capsular-bag and sulcus-fixated intraocular Lenses in Patients after primary (Duett) or secondary Implantation of an additive sulcus-fixated IOL in the same eye.

Setting

Department of Ophthalmology at the St. John's Hospital Vienna (Barmherzige Brüder Wien)

single-center retrospective analysis

Methods

In a retrospective analysis, postoperative anterior segment OCT images (swept-source OCT, Anterion, Heidelberg Engineering) were made.

Using a dynamic mathematical software program (GeoGebra Suite, Version 6.0.691.0) the tilt and centration of the capsular-bag IOL and of the sulcus-fixated IOL (Rayner Sulcoflex®) in the same eye relative to the corneal vertex were evaluated.

We evaluated 20 eyes of 10 patients with a postoperative mean time of 26.8 months.

Results

In terms of centration as well as tilt of both the capsular-bag IOL and the sulcus-fixated IOL we could see good results. The mean decentration of the capsular-bag IOL from the visual axis was 0,24 mm, that of the sulcus-fixated IOL 0,21mm. The mean tilt of the capsular-bag IOL compared to the visual axis was 1.7° degrees and the mean tilt of the sulcus-fixated IOL was 1,5°. Overall there was a slightly better centration and tilt of the sulcus-fixated IOL compared to the capsular-bag IOL in the same eye.

Conclusions

In our study, we could show that both the capsular-bag IOL as well as the sulcus-fixated IOL show good centration and low degrees of tilt. To our knowledge, this was the first study to assess tilt and centration of the Rayner Sulcoflex using anterior-segment OCT.
