“…We detected CME in one patient, secondary glaucoma in one, dense IOH in one, and retinal detachment in one. Complication rates were comparable in the present study to similar previous studies (9,10) . Previous studies have used iris claw lenses for iris fixation to correct aphakia in vitrectomized eyes (25,26) .…”

“…During PPV, the iatrogenic removal of the lens capsule may be required depending on the etiology and severity of the vitreoretinal disease. Posterior chamber IOL implantation may be performed via posterior chamber transscleral fixation (1)(2)(3)(4)(5)(6)(7) , iris fixation (8)(9)(10)(11) , intrascleral fixation (12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22) , angle supported anterior chamber IOL (23,24) , or iris claw IOL implantation (25,26) . Advantages of PCIOL fixation include the distant position from anterior segment structures, such as the corneal endothelium, and proximity to the focal point of the eye where the lens is naturally si tuated.…”

“…In these cases, a small corneal tunnel incision may be used to create a closed and more stable surgical space. In cases with no capsular support, the implantation of a foldable IOL can be performed through a small corneal incision into the posterior chamber with suture fixation to the sclera or iris (4)(5)(6)(7)(8)(9)(10)(11) . Alternatively, IOL implantation can be performed through a small incision to the posterior chamber with sutureless intrascleral fixation (12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22) .…”

Purpose: To evaluate the outcomes of three different surgical techniques for foldable posterior chamber intraocular lens (PCIOL) implantation in vitrectomized eyes without capsular support. Methods: A total of 60 patients with aphakic and vitrectomized eyes without capsular support were enrolled. All patients underwent three-piece foldable PCIOL implantation into the posterior chamber through a small corneal incision. Transscleral fixation (TSF), iris fixation (IF), and intrascleral tunnel fixation (ISF) surgical techniques were performed. Results: Postoperative PCIOL subluxation or dislocation occurred in one case in the TSF group and two cases in the ISF group. Intraoperative PCIOL dislocation occurred in two patients in the IF group. The incidence of temporary postoperative complications, such as mild intraocular hemorrhage and cystoid macular edema, was higher in the ISF group. No statistically significant difference in PCIOL-related astigmatism was observed between groups. Visual acuity improved in all groups. Conclusions: Postoperative outcomes were comparable between TSF, IF, and ISF for PCIOL in vitrectomized eyes without capsular support.

“…Further, there is invariably a risk of chronic endothelial cell loss, pigment dispersion and chances of IOL dislocation due to slippage with the iris fixated IOLs necessitating a second intervention within the pediatric eye. 24 The modern generation ACIOL (Kelman Multiflex) have an open loop design with flexible haptics and a four point fixation in angle with minimal area of contact in the angle which have overcome the complications associated with older generation of ACIOLs such as pigment dispersion, glaucoma, and hyphema making them safer for use. 25 Ravalico et al 26 In view of a majority of patients with Marfan's syndrome or Marfanoid habitus in our study with axial myopia, lower scleral rigidity and a predisposition for retinal detachment, we did not prefer to place SFIOL in our group of patients.…”

PurposeSeverely subluxated crystalline lenses pose a difficult situation to anterior segment surgeons and can only be managed surgically by removal of the lens as well as the capsular bag. Several techniques have been described in literature for the management of such cases. We describe a modified technique of endocapsular lens aspiration by the limbal route for lens extraction through small incisions on the cornea.Patients and methodsThirty-two eyes of 16 consecutive patients with severely subluxated crystalline lenses were recruited in the study. All eyes underwent a modified technique of lens aspiration within the capsular bag using a single instrument, vitrectomy cutter, and irrigation cannula, followed by sacrificing of the capsular bag. The patients were either left aphakic or implanted with an open loop anterior chamber intraocular lens (ACIOL Kelman Multiflex) and prospectively followed up for a period of 3 months.ResultsThe mean age of the patients was 9 years 3 months±3 years (range 5-15 yrs). All eyes underwent complete lens aspiration within the capsular bag with no dislocation of the lens matter. ACIOL was inserted in 22 eyes (68.7%) and 10 eyes (31.2%) were left aphakic. All the surgeries were uneventful. The mean best corrected visual acuity (BCVA) at 3 months post surgery was 0.47±0.11 logMAR which was significantly better than pre-operative BCVA (P=0.001). The percentage endothelial cell loss at 3 months was 7.1%. There was no evidence of glaucoma, corneal decompensation, or retinal detachment. The astigmatism which increased from 1.45D±086 preoperatively to 3.76D±2.02 1 week post-operatively due to sutures reduced to 1.97D±0.81 post suture removal at 3 months.ConclusionThe modified technique of endocapsular lens aspiration proves to be a simple and effective method of removal of the lens-capsular bag complex in severely subluxated lenses.

RESUMOObjetivo: avaliar os resultados de uma série de casos de fixação iriana de lentes intraoculares de câmara posterior para correção de afacia, realizados no setor de catarata da disciplina de Oftalmologia da Faculdade de Medicina do ABC e compará-los a literatura existente. Métodos: estudo prospectivo de oito pacientes afácicos, que apresentavam ausência de suporte capsular adequado e foram submetidos à cirurgia para implante secundário de LIO de câmara posterior com fixação iriana seguindo a técnica modificada de McCannel. Resultados: sete dos oito pacientes (87,5%) que não tiveram complicações cirúrgicas obtiveram melhora na acuidade visual corrigida. Um paciente (12,5%) apresentou complicação intra-operatória, evoluindo com ceratopatia bolhosa do pseudofácico. Um paciente (12,5%) apresentou glaucoma secundário à dispersão pigmentar. Conclusão: em nosso estudo a técnica de fixação iriana de câmara posterior se mostrou eficaz e segura para o tratamento da afacia, em concordância com os dados da literatura.Descritores: Afacia; Implante de lente intra-ocular/métodos; Técnicas de sutura; Cáp-sula do cristalino/patologia

Iris-sutured intraocular lenses for ectopia lentis in children

Abstract: Pars plana lensectomy-vitrectomy with iris-fixation of a foldable IOL for the management of ectopia lentis yielded visual outcomes as least as good as those of optically corrected aphakia with a significant risk for dislocation.
