Summary

A prospective randomized study on patients with late in the bag intraocular lens (IOL) dislocation after cataract surgery. Two surgical techniques of suturing of IOL to the sclera will be compared in the study. IOL position will be compared between those two groups, as well to a control group consisting of ordinary pseudophakia where only measurement of IOL position will be performed.

Detailed description

In this prospective randomized study 60 patients will be included with late intraocular lens (IOL) dislocation and 60 patients in a control group with ordinary pseudophakia. Traditional surgery includes a capsular-IOL complex fixation to sclera by looping a prolene suture not only around haptics but also through capsular tissue. Such a suture may cut through the bag, which may result in a decentered IOL. A modification of "the traditional" method was created at S:t Eriks Eye Hospital in order to achieve better centration of the IOL. The study will evaluate the efficacy of these two methods. Additionally, the impact of fibrosis of capsular bag on IOL stability postoperatively will be evaluated.
