ABSTRACT
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.

PURPOSE: To compare the posterior capsule opacification (PCO) and neodymium:YAG (Nd:YAG) laser posterior capsulotomy rates associated with three different posterior chamber foldable intraocular lenses (IOL). METHODS: We retrospectively evaluated the rates of PCO and Nd:YAG laser capsulotomy in 1150 eyes two years after standard phacoemulsification with a no-stitch 3.5mm clear corneal incision (CCI) and in-the-bag implantation of one of three types of IOL: 190 eyes received a one-piece round-edged hydrogel IOL (Hydroview H60M, Bausch & Lomb); 475 eyes a three-piece round-edged silicone IOL (AMO PhacoFlex SI-40NB, Allergan); 485 eyes a three-piece square-edged soft acrylic lens (AcrySof MA60MA, Alcon). RESULTS: The PCO and Nd:YAG laser capsulotomy rates were respectively 43.15% and 20.5% in the Hydroview H60M group, 27.57% and 9.68% in the AMO PhacoFlex SI-40NB group, 10.5% and 2.47% in the AcrySof MA60MA group. CONCLUSIONS: PCO and Nd:YAG laser capsulotomy rates were significantly higher in the Hydroview H60M group and significantly lower with the AcrySof MA60MA lenses, which combine a bioactive constitutive material with the square-edged optic design.
