Objectives: To describe logarithm of the minimum angle of resolution (logMAR) best corrected visual acuity (BCVA) and intraocular pressure (IOP) after surgical management of late in-the-bag dislocation of the intraocular lens.
Subjects/methods: In a single-centre prospective study, 165 consecutive cases having surgical correction for late in-the-bag-dislocation of intraocular lenses were analysed. One-year follow-up data of BCVA, IOP and a specially created composite variable designated “IOP issue” which considered IOP ≥ 23 mmHg, ongoing pressure reducing treatment and previous pressure reducing surgery were compared with baseline values. Logistic regression was used to investigate factors with a possible influence on the results.
Results: The vast majority, 80% of patients, were operated with an anterior approach with repositioning of the present IOL. Remaining patients were managed with lens exchange via a posterior approach combined with a pars plana vitrectomy (PPV). Baseline BCVA values improved from 0.65 ± 0.48 to 0.32 ± 0.41 (p < 0.001), IOP decreased from 20.12 ± 8.4 to 18.44 ± 5.96 mmHg (p = 0.02) whereas the proportion of cases with a pressure issue remained unchanged, 47.3%, at the 1-year follow-up. Determinants for having a pressure issue at the 1-year follow-up were present a pressure issue at baseline and IOL repositioning with the anterior approach.
Conclusions: Both surgical methods provided similar visual rehabilitation to other techniques described in the literature. However, subjects whose IOL was exchanged in combination with a PPV were at lower risk for an IOP issue at the follow-up.
