Summary

The present study should investigate the influence of a capsular tension ring on postoperative rotational stability of a plate haptic hydrophilic acrylic intraocular lens. All patients will be operated on both eyes in one occasion. Both eyes receive a Zeiss 409MP plate haptic intraocular lens, while only on eye receives an additional capsular tension ring. Follow up visits take place 1 hour, 1 week, 1 month and 4 to 7 months after surgery. At the follow up visits, the actual IOL axis will be determined by retroillumination photography. IOL centration and tilt will be determined by anterior segment SS-OCT Casia II. IOLs will be implanted in 4 different axis 0 +/- 10 degrees, 45 +/- 10 degrees, 90 +/- 10 degrees, 135 +/- 10 degrees. IOL rotation, decentration and tilt then will be compared intraindividually.
