Abstract Details

Purpose:

to describe the characteristics of the eyes with late(beyond the 1st postoperative year) spontaneous intraocular lens subluxation in order to define possible risk factors for this complication.

Setting:

Department of Ophthalmology, General Hospital of Lamia, Lamia, Greece

Methods:

case-control study. 12 patients (15 eyes), 10 men and 2 women, 73-87 years old presented with IOL subluxation and were operated on during 2013-2014 in General Hospital of Lamia. The preoperative ocular characteristics as well as the patients’ demographic data were reviewed and compared to the characteristics of a random sample of 100 patients from the cataract patients’ database in General Hospital of Lamia. Results were analyzed by aparametric method (Fisher’ exact test).

Results:

IOL subluxation presented 3-12 years after phacoemulsification. All eyes involved had pseudoexfoliation syndrome before cataract surgery (p=0.000). At the time of IOL subluxation the fellow eye had anterior chamber IOL in 5/15 cases (p=0.000). The initial IOL position was in the bag in 12/15 and at the sulcus in 3/15 cases (p=0.007). 8/15 eyes suffered from glaucoma and were or had been on antiglaucoma treatment with prostaglandine analogue (5/15 (p=0.000) and 3/15(p=0.391), respectively). Phacodonesis had been identified before cataract surgery in 2 eyes (p=0.082) and capsular tension ring had been used in those cases. 3/12 patients had late IOL subluxation in both eyes (p=0.029).

Conclusions:

Pseudoexfoliation syndrome and sulcus positioning of the IOL are major risk factors for late spontaneous IOL subluxation. The role of ocular comorbidity (glaucoma, antiglaucoma treatment with prostaglandine analogues) as well as history of the fellow eye remains yet to be clarified.
