Abstract [en]

Introduction: Cataract surgery, is nowadays the most common surgical procedure performedin Sweden. Late in-the-bag intraocular lens dislocation (LITBILD), occurring many yearsafter uneventful surgery, is due to progressive zonular weakness and capsular shrinkage.Known risk factors include among others pseudoexfoliations (PXF), high myopia andprevious vitreoretinal surgery. LITBILD has been reported with an increasing frequency inrecent years. Thus, there is a value in further investigating this patient group and describerelated risk factors.

Aim: Determine the 15-year cumulative risk of LITBILD after standard cataract surgery2003 in Örebro and describe possible risk factors causing LITBILD.

Method: Retrospective nested case-control study examining patients who underwent cataractsurgery with phacoemulsification in 2003 at Örebro University Hospital. To locate patientswithin that group who sustained LITBILD ICD10 diagnosis codes relating to LITBILDcovering years 2003-2018 were assessed. Each case was matched with two controls ofidentical sex and age.

Results: The LITBILD group was 9 patients out of 1499 operated with median age atLITBILD of 80 years (range 57-82). Median time between cataract surgery and LITBILDwas 134 months (range 39-167). Glaucoma before and/or after cataract surgery and highintraocular pressure before surgery were independently statistically significant risk factors forLITBILD.

Conclusion: Patients who underwent cataract surgery 2003 had a cumulative risk of 0.6% todevelop LITBILD. 78% of patients with dislocation had one or more of the risk factorsstudied whilst the control group represented 40% (p=0.08).
