“…[9] The safety and efficacy of aphakic rehabilitation with retropupillary iris claw fixation has been studied and it has been found to be a safe procedure for rehabilitation of aphakic eyes. [561011] There are very few studies on this procedure in Indian eyes, and hence this study has been conducted. [56]…”

Context:Surgical outcome of retropupillary fixation of iris claw lens.Aims:To evaluate the various indications, intra and post-operative complications, and visual outcome of retropupillary fixation of iris claw lens in aphakic eyes.Settings and Design:The study design is a retrospective study at a tertiary eye care center.Methods:Review of medical records of 61 aphakic eyes of 61 patients, who were rehabilitated with retropupillary fixation of an iris claw lens, with a follow-up duration of at least 1 year.Statistical Analysis Used:Data analysis was performed using paired t-test and Chi-square test.Results:Mean preoperative uncorrected visual acuity was 1.66 ± 0.3 LogMAR and postoperative acuity at 1 year was 0.53 ± 0.5 LogMAR (P = 0.00001). Preoperative distant best-corrected visual acuity was 0.30 ± 0.48 LogMAR and postoperative acuity at 1 year was 0.27 ± 0.46 LogMAR (P = 0.07). Mean preoperative astigmatism was 1.43 ± 1.94 D and postoperatively was 1.85 ± 2.16 D (P = 0.0127). Mean endothelial cell count was 2353.52 ± 614 cells/mm2 preoperatively which decreased to 2200 ± 728 cells/mm2 at 1 year follow-up (P = 0.006). There was no significant difference in central macular thickness and intraocular pressure pre and post-surgery. Complications included ovalization of pupil in 9.83%, hypotony in 1.63%, toxic anterior segment syndrome in 1.63%, cystoid macular edema in 11.47%, epiretinal membrane in 3.27%, and iris atrophy in 6.55%.Conclusion:Iris claw is a safe and an effective method of rehabilitating aphakic eyes.

“…This is similar to other published findings which demonstrate that ECL is higher in the first year post aphakic Artisan IOL implantation, with a further drop noted over the subsequent years to a lesser extent-this seems to stabilise 3 years post operatively. 12,19,20 In a multicentre study of Artisan phakic IOL, ECL was found to stabilise 3 years post operatively. 19 It seems that there are two stages for ECL; the intra-operative stage, where most ECL occurs, and 2-3 years post operatively.…”

Is an iris claw IOL a good option for correcting surgically induced aphakia in children? A review of the literature and illustrative case study

Refractive correction of aphakia in childhood can be a complex management issue following lensectomy for congenital cataract or ectopia lentis. Some children have inadequate capsular support to allow an 'in the bag' or sulcus fixated intra-ocular lens (IOL). In such cases, options for refractive correction include spectacles, contact lenses, or surgically fixed IOLs. Many methods of IOL fixation have been described, but none are widely adopted in children. In recent years, the iris-fixated Artisan Aphakic IOL has gained popularity, but there is still significant concern about the rate of corneal endothelial cell loss and IOL de-enclavation. Here, we review the current literature on the use of iris-fixated IOLs in children, the published data on endothelial cell loss and de-enclavation rates. We present a case illustrating the significant improvements in quality of life, which can be seen in selected children, and also the rate of endothelial cell loss, which can be encountered after initial surgery, and a re-enclavation event. We make the case that until more data are available on normal endothelial cell decline in early childhood, in addition to age-specific rates of endothelial cell loss and de-enclavation rates following surgery, the use of iris-fixated IOLs in children will continue to be a moot point and is unlikely to be widely adopted.

“…4,15,16 The retropupillary fixated IOL also does not prevent pupil dilation for posterior segment examination and treatment purposes. 14,17 In this case of traumatized PKP, implantation of iris-claw aphakic IOL with retropupillary fixation proved to be a feasible treatment with a good outcome, although the long-term outcome is unknown.…”

SummaryWe report the correction of aphakia using an iris-claw, aphakic intraocular lens (IOL) fixated in a retropupillary location in a 17-year-old young man who suffered blunt trauma to his eye 5 months after penetrating keratoplasty (PKP). There were no intraoperative complications. At 21 months after implantation, the patient's uncorrected distance visual acuity was 20/28; his corrected distance visual acuity was 20/22, with +0.50 −3.00 × 155. Intraocular pressure was normal, and endothelial cell count was 1798 cells/mm 2 .

Posteriorly Enclavated Iris Claw Intraocular Lens for Aphakia: Long-Term Corneal Endothelial Safety Study

Abstract: Two-year results show that retroiridis-fixated iris-claw aphakic IOL implantation is an effective and safe method with regards to corneal endothelial cell loss, and a new A constant is suggested.
