Simultaneous correction of post-traumatic aphakia and aniridia with the use of artificial iris and IOL implantation

Background

Combined post-traumatic aniridia and aphakia demand extensive and complex reconstructive surgery. We present our approach for simultaneous correction of this surgical situation with the use of the ArtificialIris (Dr. Schmidt Intraocularlinsen GmbH, Germany) with a foldable acrylic IOL Lentis L-313 (Oculentis, GmbH, Germany) sutured to its surface. The novelty (our first operation was on June 2010) of this surgical technique is based on the combined use of foldable (with closed haptics) IOL and Artificialiris to correct post-traumatic aniridia and aphakia.

Methods

Four consecutive cases of combined post-traumatic lesions of iris and lens, corrected with complex device ArtificialIris and foldable IOL. In two cases, the compound implant was sutured to the sclera in sulcus during the penetrating keratoplasty; in another case, it was positioned through a corneal incision of about 5.0 mm with transscleral fixation, and in one patient with preserved capsular support and possibility of IOL in-the-bag implantation the ArtificialIris was placed in sulcus sutureless through a clear corneal tunnel.

Results

Maximal follow-up was 6 months. The complex device was placed firmly fixed within the sulcus, including in the eye implanted without sutures, and showed a stable and centered position without any tilt or torque.

Conclusion

Management of post-traumatic aniridia combined with aphakia by haptic fixation of a foldable acrylic IOL on a foldable iris prosthesis appears to be a promising approach which gives the surgeon the possibility to correct a complex lesion with one procedure, which is less traumatic and faster. Existence of foldable materials, both iris and IOL, permits relatively small corneal incisions (4.0–5.0 mm). Moreover, the custom-tailored iris prosthesis gives a perfect aesthetic result.     

Implantation of black diaphragm intraocular lenses in congenital and traumatic aniridia

PURPOSE: To evaluate the safety and efficacy of the black diaphragm intraocular lens (IOL) implantation for the treatment of congenital and traumatic aniridia. MATERIAL AND METHODS: Seven black diaphragmatic IOLs were implanted in the eyes of 6 patients between 1997 and 1998. There were 5 males and 1 female. The mean age of them was 42.8 years (range: 22-54 years). Follow-up ranged from 9 to 20 months (mean: 14.2 months). Traumatic aniridia was present in 4 eyes and congenital aniridia in 3 eyes. Pars plana vitrectomy was combined with the simple outside-in method of scleral fixation of IOLs in 6 cases. Three of these eyes were aphakic (all with traumatic aniridia) and in 3 eyes (two congenital cases, one traumatic case) subluxated lens was simultaneously removed. In one case of congenital aniridia with mature cataract, ECCE and ciliary sulcus implantation without scleral fixation were performed. RESULTS: There were very few complications. Ciliary sulcus bleeding appeared in 2 cases during scleral fixation. Transient post-operative corneal oedema was observed in 2 eyes, raised intraocular pressure in 3 eyes, and dispersed blood in vitreous cavity in 2 eyes. All IOLs were well centred. The improvement in best corrected visual acuity was achieved in 5 cases, while good pre-operative best corrected visual acuity was maintained in 2 cases. CONCLUSIONS: Diaphragmatic IOL can be fixated to the sclera in cases without capsular support or it can be implanted into ciliary sulcus after ECCE. Reconstruction of 5 mm pupil and intraocular correction of aphakia enable good visual rehabilitation of patients. The combined procedure of pars plana vitrectomy and scleral fixation of diaphragmatic lens is safe and effective in traumatic and congenital aniridia.     

Black diaphragm aniridia intraocular lens for congenital aniridia: long-term follow-up

PURPOSE: To present long-term results of implantation of a black diaphragm aniridia intraocular lens (IOL) in eyes with congenital aniridia. SETTING: Eye Hospital, Heinrich-Heine-University, Düsseldorf, Germany. METHODS: Cataract surgery was performed in 19 eyes of 14 patients with congenital aniridia. The black diaphragm aniridia IOL was implanted in front of the capsular bag in the ciliary sulcus. Mean patient age was 30 years (range 10 to 59 years) and mean follow-up, 46 months (range 12 to 84 months). Before surgery, corneal epithelial disorders; corneal pannus; cataract; hypoplasia of the macula, optic nerve, or both; and nystagmus were present in all 19 eyes. Clinically detectable glaucoma was present in 5 eyes. RESULTS: Despite the presence of amblyopia and nystagmus, visual acuity improved in 14 of the 19 eyes. The main postoperative problems were glaucoma deterioration (4 of 19 eyes) or development (4 of 19 eyes), cystoid macular edema (2 of 11 eyes), chronic endothelial cell loss (3 of 11 eyes), and progression of corneal epithelial disorders (4 of 19 eyes). Glaucoma was controlled by medical or surgical therapy in all patients. Intraocular lens explantation was performed in 2 eyes with glaucoma. CONCLUSION: Implantation of the black diaphragm aniridia IOL improved visual acuity in the majority of patients with a variety of endogenous problems in addition to aniridia.     

Implantation of a black diaphragm intraocular lens in ten cases of post-traumatic aniridia

PURPOSE: To retrospectively review the safety and efficacy of black-diaphragm intraocular lenses (IOL) implanted for the treatment of post-traumatic aniridia. METHODS: Ten patients (mean age 48 years, range 21-75) were implanted with a black-diaphragm posterior chamber IOL (Morcher GmbH, model 67F) for correction of post-traumatic aniridia associated with cataract or aphakia. This IOL, in poly(methylmethacrylate), consists of an opaque diaphragm surrounding the transparent optic, and was inserted through a 10-mm scleral tunnel (seven eyes) or through the corneal trephination in cases of simultaneous penetrating keratoplasty (three eyes), and in-the-sulcus implanted, trans-sclerally sutured (six eyes) or on capsular support (four eyes). Mean follow-up was 33.4 months (range 12-52). RESULTS: Best-corrected visual acuity (BCVA) improved in eight eyes and remained unchanged in two. Glare and photophobia decreased in all patients. Intraoperatively, ciliary sulcus bleeding occurred in two cases and haptic rupture during lens insertion in one. Postoperatively, persistent intraocular inflammation was seen in four eyes, secondary glaucoma in four eyes, transient hyphema and/or hemovitreous in four, IOL decentration in two, and post-traumatic haptic detachment in one eye. CONCLUSIONS: Although in our experience the haptics still seem weak and the diaphragm diameter too large, implantation of the black-diaphragm IOL type 67F appeared sufficiently safe and provided satisfactory functional results for correction of post-traumatic aniridia combined with cataract or aphakia, improving BCVA and reducing glare and photophobia in most patients, though clearly more cases and longer follow-up are needed to assess its clinical performance properly.     

Black diaphragm aniridia intraocular lens for aniridia and albinism

Background Our aim was to assess the safety and efficacy of primary and secondary implantation of a black diaphragm aniridia intraocular lens (IOL) in patients that lacked a complete iris diaphragm.Methods This was a retrospective non-comparative study of six eyes in five patients with iris defects. The causes of such defects included congenital aniridia, traumatic aniridia, and oculocutaneous albinism. Three eyes underwent primary implantations of a black diaphragm IOL, and three eyes were given secondary implantations. The visual acuity, subjective severity of glare, postoperative anatomical outcome and any intraoperative or postoperative complications were reviewed.Results The mean follow-up period was 20.6 months (range 3–29 months). All patients showed stable or improvement in best-corrected visual acuity postoperatively. Glare and photophobia had improved subjectively in all patients after implantation of the black diaphragm IOL. Intraoperative complication included one case of hyphaema and iris damage during insertion of the IOL. Postoperative complications included intraocular inflammation with choroidal detachment, secondary glaucoma, and persistent epithelial defect after surgery. None of the patients developed decentration of IOL after surgery.Conclusion The black diaphragm aniridia IOL is useful in the management of the condition in patients with iris deficiency including oculocutaneous albinism. Intraoperative and postoperative complications are not uncommon, and patients should be monitored carefully in the perioperative period.

Aniridie-Intraokularlinsen bei Augen mit traumatischen Irisdefekten

BACKGROUND: Globe injuries frequently are the cause of permanent loss of visual function. Especially ruptures of the globe have a 50 times lower chance of achieving a final visual acuity better than 20/200 as compared to contusions of the globe. Besides injury to the retina and choroids, injury of the iris-lens diaphragm plays an important role for visual rehabilitation (10% iris defects and 1% aniridia after blunt trauma). Against this background the surgical results after implantation of aniridia intraocular lenses were investigated. PATIENTS AND METHODS: Eleven patients (41.9+/-19.6 years of age) after globe injury (three ruptures of the globe, eight penetrating injuries with trauma of the iris) were implanted with an aniridia IOL. RESULTS: The implantation of an aniridia IOL was performed on average 1.0+/-0.6 years (range: 0.4-2.3 years) after the primary injury. In ten eyes an aniridia IOL model HMK ANI 2 (Ophtec/Polytech) was implanted and in one eye an aniridia IOL model 67 (Morcher). Most patients were very satisfied with the results achieved (average corrected visual acuity 0.48; 0.05-1.0). Of the operated eyes, 63% reached a visual acuity >/=0.4. All patients noticed a significant reduction in glare disability as compared to the preoperative condition. The incidence of secondary glaucoma remained unchanged after the secondary implantation. One patient demonstrated retinal detachment 3 months after receiving the secondary implant, which was successfully treated with vitrectomy and gas tamponade. CONCLUSIONS: The implantation of aniridia IOLs seems to be a beneficial therapeutic option in post-traumatic eyes with partial or complete aniridia and aphakia with good visual recovery. During the postoperative follow-up special attention must be paid to sufficient regulation of intraocular pressure and to the retinal situation.     

The artificial iris – Analysis of various implantation techniques after ocular trauma

Purpose:The aim of this study is to analyze the outcome of various techniques for a custom-made iris prosthesis implantation as part of reconstructive anterior segment surgery following traumatic aniridia.Methods:This retrospective interventional study was done for 6 eyes that received an artificial iris as secondary reconstructive measure for photophobia and unsatisfactory vision following initial globe repair. Different implantation techniques were employed. These included simple sulcus implantation, implantation of a composite (iris prosthesis with attached intraocular lens) implant, and combinations with phacoemulsification, vitrectomy, and penetrating keratoplasty.Results:In all cases, the artificial iris was implanted successfully. In the follow-up period (1–48 months), postoperative complications included rhegmatogenous retinal detachment, prolonged intraocular inflammation, and corneal transplant decompensation due to graft rejection. There was no case of secondary glaucoma. Complications could be managed successfully. All patients showed improved best-corrected visual acuity and were satisfied with functional and cosmetic results.Conclusion:This case series highlights the different implantation techniques for reconstruction of the anterior segment after ocular trauma. The versatility of the custom-made iris implant accounts for a wide range of applications and the foldable material reduces the need for large incisions in the already traumatized eye.

K��nstliche Iris

The flexible iris prosthesis according to Koch with a customized iris design serves for anterior segment reconstruction in patients with partial or complete aniridia. It is designed for implantation in the ciliary sulcus and is recommended only for pseudophakic or aphakic eyes. The multilayered implant consists of a core of a silicone matrix with incorporated color pigment coated with another layer of medical grade silicone. As a design variant the implant is available with or without an additionally embedded tissue layer. Without tissue the implant is more flexible, can be easily folded and perfectly adapts to the anatomical course of the sulcus. In contrast, implants with tissue show a greater rigidity and provide a better grip for sutures. This article describes various techniques for implantation of partial and full prostheses and gives instructions for calculating the implant size. Full prostheses can be combined with other reconstructive measures, such as sutured intraocular lenses and are particularly helpful in silicone oil surgery by avoiding endothelial contact. With careful consideration of the indications and application the flexible iris prosthesis is a valuable extension of the spectrum of reconstructive anterior segment surgery.

Lens implant selection with absence of capsular support

If contact lens or spectacle correction is not viable, little debate exists that the secondary placement of an intra-ocular lens (IOL) is the method of choice in the absence of capsular support. The choice of IOL mainly depends on the preoperative status of the eye (eg, aphakia in children) and the selected location for the implant. Theoretically, there are several IOL implantation approaches in cases without capsular support: an angle-supported anterior chamber (AC) IOL, an iris-fixated ACIOL, an iris-sutured or iris-fixated posterior chamber (PC) IOL and a transsclerally sutured PCIOL. No consensus exists, however, on the indications as well as on the relative safety and efficacy of these different options. Implantation of modern ACIOLs, like the refined open-loop or iris-fixated claw (toric) ACIOLs, have regained popularity and provide a valuable alternative to sutured PCIOLs. However, in the absence of capsular support, the transsclerally sutured PCIOLs offer numerous advantages for certain eyes. Because of its anatomic location, the sutured PCIOL is more appropriate for eyes with compromised cornea, peripheral anterior synechiae, shallow anterior chamber, or glaucoma. Moreover, sutured PCIOLs are appropriate if the patient with aphakia is young or has a life expectancy of 10 years or more. Recent technological advances, including PCIOL with iris diaphragm for aniridia, toric ACIOLs, and small-incision surgery with foldable, transsclerally sutured IOLs, seem to further improve clinical outcomes.

Implantation of a black diaphragm intraocular lens for traumatic aniridia.

PURPOSE: To evaluate the suitability and safety of a black diaphragm posterior chamber intraocular lens (IOL). SETTING: Department of Ophthalmology, Leeds General Infirmary, Leeds, United Kingdom. METHODS: Seven patients who had secondary implantation of a Morcher 67G black diaphragm posterior chamber IOL were identified. All patients were men with a mean age of 42 years who had previous ocular trauma resulting in extensive loss of iris tissue (traumatic aniridia). Simultaneous penetrating keratoplasty was performed in 4 cases. Minimum follow-up was 10 months (mean 19 months). RESULTS: Best corrected visual acuity improved in 5 cases and was unchanged in 1 case. The lens was well centered in 5 cases. Two cases developed secondary glaucoma, 1 requiring trabeculectomy. One case developed infective endophthalmitis but had a visual acuity of 6/18 at last follow-up, and 1 had a vitreous and anterior chamber hemorrhage, which resolved. CONCLUSIONS: The black diaphragm posterior chamber IOL overcame aphakia in eyes with considerable loss of iris tissue and may mitigate the visually disabling effects of traumatic aniridia. Although this lens appears safe, caution should be used in its implantation until more patients with longer follow-up are studied.     

Black diaphragm intraocular lens implantation in aphakic eyes with traumatic aniridia and previous pars plana vitrectomy

PURPOSE: To evaluate the efficacy of secondary black diaphragm intraocular lens (IOL) implantation in aphakic eyes with traumatic aniridia and previous pars plana vitrectomy (PPV). SETTING: Shandong Eye Institute and Hospital, Qingdao, China. METHODS: This retrospective study comprised 15 aphakic eyes with aniridia and no vitreous that had implantation of a secondary black diaphragm IOL 6 to 72 months after PPV. The PPV was performed as a result of trauma to the posterior segment. Before implantation of the IOL, all patients had reduced visual acuity from aphakia and intolerable glare from aniridia. Eyes were aphakic as a result of previous extracapsular cataract extraction (1 eye), lens extrusion during trauma (3 eyes), or simultaneous cataract lensectomy during PPV (11 eyes). Significant iris defects were present, with 9 eyes being aniridic after the injury. The mean follow-up was 17 months (range 3 to 34 months). The postoperative visual acuity, intra- ocular pressure (IOP), endothelial cell density, IOL centration, and intraocular inflammation were monitored. RESULTS: All 15 eyes had improved visual acuity and marked glare reduction after IOL implantation. No major IOL decentration was seen. Five patients had increased IOP 3 to 5 days after IOL implantation; 3 were known to have secondary glaucoma from trauma before surgery and their IOP was controlled preoperatively (< 21 mm Hg) with timolol 0.5% eyedrops. The other 2 patients had normal- appearing angles, and 1 was diagnosed with hemolytic glaucoma after IOL insertion. Postoperative elevated IOP was controlled by timolol eyedrops (4 eyes) or selective laser trabeculoplasty (1 eye). Hyphema was seen in 1 patient on the first day after IOL implantation, but no further bleeding was noted. Vitreous hemorrhage was seen the first day after IOL insertion in 2 patients. One resolved without sequelae; the other required vitreous washout. Retinal detachment and cystoid macular edema did not occur in any patient. CONCLUSIONS: Black diaphragm IOL implantation can be considered in eyes with coexisting aphakia and aniridia and without vitreous. Intraoperative IOP regulation is crucial in vitrectomized eyes to prevent complications such as expulsive hemorrhage. In general, visual function was better after IOL insertion as a result of better visual acuity and glare reduction. Although this IOL appears to be safe, long-term results must be assessed in studies with a longer follow-up and a larger study group.
