Safety Profile Of Intraocular Lens Dislocation Surgery: A Retrospective Cohort Study

to compare the surgical outcomes and complications of refixation vs. exchange of dislocated intraocular lenses (IOLs) in patients who underwent transscleral suture fixation, iris suture fixation or intraocular lens exchange for the treatment of IOL dislocation. 

Department of Ophthalmology, General Hospital of Lamia, Lamia Greece

A total of 66 eyes (n = 64 patients, 38 men &26 women) with postoperative follow-up of ≥6 months were evaluated: 26 received refixation of dislocated posterior chamber IOL (refixation group I) via transcleral suturing, 18 received refixation with iris suturing of the haptics (refixation group II) while 8 received IOL exchange with anterior chamber IOL (exchange group) treatment. Treatment outcomes, including best-corrected visual acuity (BCVA), spherical equivalent, corneal cylinder, intraocular pressure (IOP), central macular thickness (CMT) and perioperative and postoperative complications were retrospectively reviewed.

No significant differences were found in BCVA, spherical equivalent, cylinder, IOP, or CMT changes. The exchange group experienced significantly more frequent vitreoretinal complications than the refixation group (p=0.041). 

Without any reason to extract the dislocated IOL, reuse of the dislocated IOL via transscleral suture fixation would be a better surgical option to prevent postoperative vitreoretinal complications.
