Implantation of a phakic iris claw intraocular lens is a common, effective and safe procedure to correct high myopia, hyperopia and astigmatism [2]. Due to the nature of its fixation on the iris using claws, chronic irritation and inflammation have remained a major concern with the Artisan® lens since its market introduction in 1998. Following iris claw implantation, monitoring of postoperative inflammation is mandatory [4][7]. Usually, signs of inflammation can be detected in the anterior chamber during the early postoperative period. We present here the first case of late-onset inflammation after implantation of an iris claw lens triggered by an iris varix.
The iris varix is a rare benign iris vascular abnormality, with a low prevalence as a solitary primary lesion in the general population and little is known about its clinical characteristics [1][5][6]. This report shows that an iris varix could be a cause of a late onset and chronic inflammation after phakic Artisan® lens implantation.
