超声乳化白内障吸除联合人工晶状体(intraocular lens,IOL)囊袋内植入已成为白内障的标准术式.但若术中发生晶状体后囊膜破裂,就必须放弃IOL的囊袋内植入,采用其他方法[1],如前房虹膜固定、后房虹膜固定或后房巩膜缝线固定等.房角支撑型IOL植入技术相对简单、眼内操作步骤少、眼内干扰少、无需特殊器械设备,易于掌握和实施,是手术条件受限时常用的方法.但处理不当可出现一些并发症,如瞳孔变形、眼压升高、葡萄膜炎,甚至视网膜脱离、角膜内皮失代偿等. 相似文献

AIM: To analyse the occurrence of the anterior capsule contraction following cataract surgery. Capsule contraction syndrome (CCS) is defined as an extreme reduction in diameter of anterior capsulectomy, capsular bag diameter and, occasionally, displacement of the IOL after extracapsular cataract extraction. It is relatively frequent in pseudoexfoliation, advanced age, in association with uveitis, pars planitis and myotonic muscular dystrophy. MATERIALS AND METHODS: 5965 eyes of patients were operated on cataract between 1.01.1994 and 31.12.1997 in Tadeusz Krwawicz Chair of Ophthalmology and 1st Eye Hospital, Medical School in Lublin. Two types of surgical procedures were performed: "divide and conquer" phacoemulsification with 4.5-8 mm continuous curvilinear capsulorhexis (3385 eyes) and extracapsular cataract extraction with "can opener" capsulotomy (2580 eyes). RESULTS: 20 cases of clinically apparent CCS were referred to the Department: in the course of intensive postoperative inflammation--5, in patients over 80--4, in pseudoexfoliation syndrome--2, myotonic dystrophy--1, ectopia lentis--2, other causes--6. In order to improve visual acuity in 4 cases surgical removal of the distorted and opaque anterior capsule was performed, in 3 cases relaxing radial tears were done, in 3 cases secondary anterior capsulotomy was performed using Q-switched Nd:YAG laser. CONCLUSIONS: In cases where the occurrence of CCS is especially high large diameter capsulorhexis should be performed and IOL designed to provide maximal peripheral capsular bag expansion should be implanted. 相似文献

Dislocation of an intraocular lens (IOL) with the capsular bag is a late complication of cataract surgery, reported with increasing frequency in recent years. Pseudoexfoliation, uveitis, myopia, and other diseases associated with progressive zonular weakening and capsular contraction are the predisposing conditions. Capsular tension rings probably help but do not prevent this complication. Management includes IOL exchange, replacement with an anterior or a sutured posterior chamber IOL, or suturing the IOL through the bag to the iris or the sclera. 相似文献

PURPOSE: To evaluate the uveal and capsular biocompatibility of hydrophilic acrylic (Hydroview) and hydrophobic acrylic (AcrySof) intraocular lenses (IOLs) after phacoemulsification in eyes with pseudoexfoliation syndrome (PEX) or uveitis and compare the results with those in a control group. SETTING: Department of Ophthalmology, University of Vienna, Vienna, Austria.METHODS: This prospective nonrandomized comparative trial comprised 143 eyes recruited consecutively. Of these, 49 eyes had PEX, 43 had uveitis, and 51 served as controls. A standardized surgical protocol was used. Cell reaction, anterior (ACO) and posterior (PCO) capsule opacification, and flare were evaluated 1 year after cataract surgery. RESULTS: Regarding uveal biocompatibility, the number of foreign-body giant cells (FBGCs) increased in proportion to associated ocular pathologies in both IOL groups. The difference between the Hydroview control and Hydroview uveitis groups was statistically significant. The number of FBGCs was greater on AcrySof IOLs than on Hydroview IOLs in all 3 groups. The difference in FBGCs between the 2 IOL types was statistically significant in the control and PEX groups. Regarding capsular biocompatibility, lens epithelial cell (LEC) outgrowth was inversely correlated with intraocular inflammation. Outgrowth was statistically significantly higher with Hydroview IOLs, occurring in 85% in the control group, 45% in the PEX group, and 28% in the uveitis group (P <.0001). With AcrySof lenses, the percentages were 0%, 8%, and 4%, respectively. The PEX and uveitis groups were more likely to develop ACO than the control group (P <.012). There was no statistically significant difference in ACO between the 2 IOL types in the 3 patient groups. The PCO was statistically significantly greater in the uveitis group than in the control group (P <.026) and statistically significantly more dense on Hydroview than on AcrySof IOLs in all 3 patient groups (P <.002). Flare was statistically significantly higher in the uveitis group than in the PEX and control groups with both IOL types (P <.012). There was no statistically significant difference in flare between the 2 IOL types. CONCLUSIONS: Uveal and capsular biocompatibility depends on the intensity of ocular inflammation. The greater the inflammation, the less the biocompatibility of hydrophilic and hydrophobic acrylic materials. AcrySof stimulated more FBGCs. The Hydroview material had better uveal but poorer capsular biocompatibility than AcrySof. The sharp optic edge effect of the AcrySof IOL and the advantages of the Hydroview lens in normal eyes are less apparent in compromised eyes. 相似文献

Purpose: Management of uveitic cataract in patients with juvenile idiopathic arthritis (JIA) is challenging, and intraocular lens (IOL) implantation is controversial. This study investigated the outcome after minimally invasive surgery with IOL implantation. Methods: Retrospective analysis after phacoemulsification with in‐the‐bag IOL implantation was performed in 16 patients (17 operations) with ANA‐positive JIA‐associated chronic uveitis. In these patients, 25 G capsulectomy and anterior vitrectomy was performed and they received an intravitreal triamcinolone (TA) injection. Results: Mean age at uveitis onset was 5 ± 2 years, and surgery was performed at a mean age of 11 ± 2.2 years. Preoperatively, uveitis was inactive in all patients, and visual acuity was logMAR 0.8 ± 0.44; additional uveitis complications were present in all patients, and 15 patients were receiving systemic immunosuppression/biologicals. After surgery (mean follow‐up 26.5 ± 11.7 months), presence of cystoid macular oedema, papilloedema, ocular hypertension/glaucoma and hypotony did not increase compared with baseline. There was no significant worsening of AC inflammation (by cell numbers and laser flare values). IOL deposits persisted in four patients, and synechiae developed in eight. The visual acuity was improved (≥2 lines) in all patients (mean logMAR 0.3 ± 0.24). Retrolental membrane formation was not noted. Secondary capsular opacification was observed in seven patients, requiring Nd:YAG capsulotomy in five of them. Conclusions: Phacoemulsification and in‐the‐bag IOL implantation may improve visual outcome in JIA‐associated uveitis with minimally invasive surgical technique and intravitreal TA injection. Well‐controlled uveitis with appropriate use of topical steroids and systemic immunosuppression or biologicals appears as a perioperative requirement. 相似文献

Implantation of iris-claw Artisan intraocular lens for aphakia in Fuchs’ heterochromic iridocyclitis
Implantation of iris-claw Artisan intraocular lens (IOL) is a surgical option for correction of aphakia; however, these IOLs have not been used in eyes with uveitis including Fuchs’ heterochromic iridocyclitis (FHI) due to possible risk of severe postoperative intraocular inflammation. In the case reported here, we secondarily implanted an Artisan IOL in a 28-year-old man with FHI who had aphakia with no capsular support due to a previous complicated cataract surgery. Enclavation was easily performed and no intraoperative complication was noted. Postoperative course was uneventful with no significant anterior chamber inflammation during 12 months of follow-up. Although there were few deposits on the IOL surface, the patient achieved a best-corrected visual acuity of 20/20 without developing glaucoma or other complications. Therefore, Artisan IOL may be considered for correction of aphakia in patients with FHI. However, studies on large number of patients are required to evaluate safety of the procedure. 相似文献

Different surgical methods are used to fixate the subluxated sulcus intraocular lens (IOL) in the absence of in-bag fixation, ranging from iris and scleral suturing to optic capture of the IOL. A new technique, which we have termed capsule membrane suture fixation, provides an additional method for securing a subluxated or decentered sulcus-based IOL to the remnant capsule or a capsular membrane. This method can also be used in secondary surgery for fixation, repositioning, or removal and replacement of IOLs. In this technique, the IOL haptics are sutured to the fibrotic elements of the capsular membrane to center and secure the IOL to the capsular membrane and prevent complications associated with uveal touch. 相似文献

Beh?et's disease is 1 of the most common causes of uveitis in the Eastern world. Its common ocular complications are uveitis, cataract, and obliteration of retinal vessels. Phacoemulsification with intraocular lens (IOL) implantation in patients with Beh?et's disease is known to be a safe procedure. We managed a patient with Beh?et's disease who had aggravated uveitis and opacification of a hydrophilic acrylic IOL (ACRL-C160, Ophthalmed) 4 months after cataract surgery. Recalcitrant uveitis despite maximum tolerable medication and IOL opacification with vitreous opacity necessitated an IOL exchange and trans pars plana vitrectomy. After the procedure, the eye became quiescent. However, the visual acuity was 20/200 because of the obliteration of retinal vessels. 相似文献

ABSTRACTIntraocular lens (IOL) implantation in pediatric eyes with insufficient capsular support is challenging and there are multiple IOL options. These include placement of an IOL within the capsular bag with a capsular tension ring, a scleral-fixated posterior-chamber IOL (PCIOL) with or without capsular tension segment or ring, an intra-scleral fixated IOL, an iris-sutured PCIOL, or an anterior chamber iris-fixated IOL. We reviewed 48 articles and 1 published abstract describing the surgical techniques, complications and visual outcomes of different IOL options in the management of aphakic pediatric eyes with insufficient capsular support. The present review found that the visual acuity outcomes of various IOLs are comparable. Furthermore, each IOL design and surgical technique has different rates of serious complications, including IOL dislocation or decentration, intraocular hemorrhage, glaucoma, endothelial cell loss, and endophthalmitis. An understanding of the risks and benefits of different IOL designs is important for counseling patients and families. 相似文献
