Endocapsular iris reconstruction implants for acquired iris defects: a clinical study

Abstract

In patients with acquired iris defects, implantation of endocapsular IRI during cataract surgery appears to be a safe and effective procedure. At a mean time gate of 29 months, both IOLs and IRI appeared to remain stable within the capsular bag.

Safety of an artificial iris in a phakic eye

“…17 The implantation of an artificial iris has always been reported in combination with cataract surgery, which includes implantation of an IOL. 13,17,18 Only a few cases of iris reconstruction in a phakic eye using an iris-clip IOL have been reported; eg, 1 case of implantation of an iris-repair iris-clip IOL in a phakic eye after penetrating ocular trauma 5 and another case of iris reconstruction after sectorial iridectomy in a phakic eye presenting an iris melanoma. 16 In this paper, we report a case of a sectorial foldable artificial iris implant in a phakic eye with a 1-year follow-up.…”

“…The clinical efficacy and safety of these techniques have been addressed. 17,18 The implantation of a black diaphragm IOL, made of poly(methyl methacrylate) and positioned in the posterior chamber, has been frequently used and described. 4,19 However, the use of an artificial iris implant was introduced only recently.…”

Outcomes of prosthetic iris implantation in patients with albinism

“…However, the endocapsular devices remained stable within the capsular bag in this series, as described in other reports. 16,18 Whether placement of the IOL is easier or preferred in front of or behind the new iris diaphragm has not been established. There may be implications for effective IOL power, depending on the IOL location chosen.…”

“…3,[13][14][15] We and others have published preliminary reports of the initial experience with the single-piece iris-diaphragm IOL and endocapsular prosthetic iris devices. [16][17][18] In this series, simultaneous implantation of an IOL and 3 different prosthetic iris devices in patients with albinism and congenital iris deficiency was evaluated. Light entering the posterior segment was reduced by inserting 2 multiple-fin rings (types 50C and 50D) in the capsular bag and then rotating the rings until the fins interdigitated.…”

“…Morcher also has a limited number of rings that are intended for placement in the ciliary sulcus. Single case reports 20,23 and small series reports [12][13][14][15][16][17][18]21,[24][25][26][27] evaluating the long-term safety and efficacy of Morcher iris prostheses have in general been favorable, although few clinical trials have been performed. Morcher artificial iris devices are no longer available in the United States through the U.S. Food and Drug Administration's (FDA) compassionate-use device exemption pathway.…”
