The frequency of late in-the-bag intraocular lens (IOL) dislocation has increased over the past decades. Important predisposing factors are pseudoexfoliation syndrome (PXF), myopia, previous vitreoretinal surgery, and trauma,1–3 and there is also an association with glaucoma.1–4 Furthermore, some studies report high intraocular pressure (IOP) in eyes with IOL dislocation despite no known glaucoma.1–5 Accordingly, it has been speculated whether the dislocation can cause an IOP increase.
In a recent study addressing the association between high IOP and spontaneous in-the-bag IOL dislocation, Lorente Bulnes et al.6 found a significant trend toward higher IOP when a lower grade of dislocation was diagnosed. They suggested that movement of the loosened IOL in mild dislocation might cause iris chafing. The aim of the present analysis was to evaluate the possible association between the IOP at diagnosis and the grade of IOL dislocation in a large clinical trial.
