To evaluate causes of explantation of the implantable contact lens (ICL), a posterior chamber phakic intraocular lens (IOL) widely used at KKESH for the correction of ametropias.
A retrospective chart review of patients who underwent ICL procedure from 2007 to December 2012 was performed to evaluate the causes and outcome of ICL explantation.
A total of 532 eyes have been performed during the study period, 263 eyes their charts reviewed. In 20 eyes the ICL was explanted, from those nine were exchanged. The most common cause of explantation was wrong size of the lens due to inaccurate white to white measurement in 13 eyes.7 eyes ICL were exchanged with more accurate size. 2 eyes ICL were exchanged because of high residual astigmatism.1 eye ICL explanted because of rhegmatogenous retinal detachment. Another eye was explanted due to glare. Lens aspiration with posterior chamber IOL required in four eyes.
The ICL is an effective method to correct ametropia, but some selected cases require explantation/exchange due to unavoidable and avoidable cases. More accurate methods for size selection are needed to lower exchange rate.
