The clinical effect of retroiris fixed iris-clip intraocular lens in aphakic eyes

Objective To observe the clinical effect of the ARTISAN iris-clip intraocular lens implanted through the retroiris fixation in aphakic eyes.Methods A retrospective analysis from January 2010 to April 2011,aphakic patients in 16 cases (16 eyes) without capsular support,through the implantation of ARTISAN iris-clip intraocular lens with retroiris fixed,and to observe their postoperative changes of visual acuity,corneal endothelium cells,intraocular pressure and other changes.Results Sixteen patients with preoperative best corrected visual acuity was 0.46 ± 0.19,postoperative uncorrected visual acuity was 0.50 ± 0.20 (P ＜0.05).Sixteen patients with preoperative corneal endothelial cell count (1914 ± 151)/mm2,1 year after (1835 ± 145)/mm2,the average corneal endothelial cell loss rate was 4.1％.No significant changes in intraocular pressure after operation in all the cases.One case appeared symptom of glare after operation.No other complications such as intraocular lens dislocation were seen in all the cases.Conclusions This study suggests that retroiris fixed iris-clip intraocular lens insertion is a safe and simple surgery,and is beneficial in aphakia patients to acquired better visual acuity.The retroiris fixed iris-clip intraocular lens implantation seems to be an ideal treatment to the aphakia patients without capsular support in current.
