About

A prospective randomized study on patients with late in the bag intraocular lens (IOL) dislocation, after cataract surgery. To obtain normal visual function, these patients needs surgery. In this study the investigators will look for advantages and dis-advantages after two different surgical approaches to late in-the-bag IOL dislocation.

Full description

In this prospective, randomized study The investigators will include at least 80 patients with late intraocular lens (IOL) dislocation in the capsular complex, after cataract surgery. To obtain normal visual function, these patients needs surgery. Today, there are two different methods used for this condition; scleral suturing of the capsular complex or exchange of IOL to an iris-fixated IOL (Verisyse). In this study the investigators will look for advantages and dis-advantages for these two methods.
