Abstract Details


To evaluate the impact of a capsular tension ring (CTR) on the rotational stability of a spherical, single-piece, hydrophilic-acrylic intraocular lens (IOL) with an open-loop haptic design. The observation period started at the end of surgery and lasted 6 months.


Department of Ophthalmology, Medical University of Vienna, Austria


100 eyes received a capsular tension ring (CTR 13/11, Human Optics, Germany) and an ASPIRA®-aA IOL (Human Optics, Germany) during cataract surgery. IOL orientation was documented at the surgery table after closure of the incision as well as after 1 hour, 1 week and 6 months. Measurement of IOL rotation avoided bias from cyclorotation or head tilt. The control group consisted out of 100 eyes which received only an ASPIRA®-aA IOL.


Regarding the absolute IOL rotation from end of surgery to 6 months there was no statistically significant difference between IOLs with CTR and IOLs without CTR: 4.9 degrees (range 0 to 28.3) and 3.7 degrees (range 0.4 to 50.3) respectively (p=0.155). IOLs with CTRs exhibited a different rotational tendency during the course of the follow-up than IOLs without a CTR: For IOLs with a CTR we observed the least rotation within the first hour, thereafter IOL rotation increased. In contrast median absolute IOL rotation in eyes without a CTR decreased in the course of the follow-up.


We found no evidence for better rotational stability in eyes with a capsular tension ring compared to eyes without CTR.
