Comparisons of Visual and Surgical Outcomes after Reuse or Replacement of Dislocated in-the-Bag Intraocular Lens

Abstract EN

Purpose.

To compare the visual and surgical outcomes after a reuse or a replacement of a dislocated in-the-bag intraocular lens (IOL).

Methods.

This was a retrospective, nonrandomized case series at a single ophthalmological institution.

Cases with an in-the-bag dislocation of an IOL were treated by pars plana vitrectomy and the reuse or the replacement of the IOL.

The lens was held by intrascleral fixation of the haptics of the IOL under both conditions.

The same dislocated IOL was reused in 6 eyes (group A) or it was replaced with another IOL in the other 9 eyes (group B).

The pre- and postoperative parameters analyzed included the visual acuity, refractive error, corneal endothelial cell density, and intraocular pressure (IOP).

Results.

There was no significant difference between the two groups in the postoperative visual acuity (P=0.388), refractive error (P=0.955), IOP (P=0.529), and endothelial cell loss (P=0.940).

A breakage or a tilting of the IOL was observed and required replacement in three eyes in the reuse group (P=0.044).

Conclusions.

Half of the cases with reused in-the-bag dislocated IOL had a breakage or a tilting of the IOL.

The replacement of the in-the-bag dislocated IOL is better than the reuse of the IOL with intrascleral haptics fixation.
