目的 用超声生物显微镜观察老年性白内障囊外摘除术及后房型人工晶体植入术后房角的变化及相关因素。方法 用超声生物显微镜观察老年性白内障囊外滴除术及后房型人工晶体植入术后,31例(41只眼)的房角改变。结果 虹膜周边前粘连6只眼,瞳孔变形12只眼,均与人工晶体襻的位置有关;关非所有非囊袋内固定的人工晶体襻均位于睫状体沟;术后残留的晶体皮质,术后3个月仍存留,较多晶体皮质的残留可引起周连虹膜膨隆、房角变  相似文献

PURPOSE: Intraocular lens (IOL) haptic position in 35 eyes that had undergone cataract surgery was examined with ultrasound biomicroscopy (UBM). METHODS: In a prospective randomized study the patients were operated by phacoemulsification using continuous curvilinear capsulorhexis (CCC) (group I) or by extracapsular cataract extraction (ECCE) using linear capsulotomy (group II). Ultrasound biomicroscopy was used to localize both haptics of the implanted intraocular lenses and to measure anterior chamber depth (ACD), iris thickness and anterior chamber angle. The inflammatory reaction in the anterior chamber was assessed with laser flare photometry. Slit lamp examination was performed. RESULTS: Both IOL haptics were found in the lens capsule in all 18 eyes in group I. In group II one of the haptics was located out of the capsule in 7 of 17 eyes (41%). The difference is statistically significant (p=0.01). Postoperatively mean ACD measured with the UBM was 4.06+/-0.30 mm in group I and 3.64+/-0.24 mm in group II (p=0.00025). CONCLUSION: The UBM examinations indicate that phacoemulsification with continuous curvilinear capsulorhexis is a more reliable technique than ECCE with linear capsulotomy to achieve implantation of the intraocular lens haptics in the capsular bag.  相似文献

We aimed to evaluate the implantation of a posterior chamber intraocular lens (IOL) in the anterior chamber (AC) with the haptics passing through two iridectomies to the posterior chamber. A total of 33 eyes of 33 patients with inadequate posterior capsular support due to either previous aphakia or posterior capsular rupture during cataract extraction were included in the study. A double iridectomy was performed on all patients using a vitrectomy probe on the midperiphery of the iris. IOLs were implanted in the AC, and the haptics were passed through the iridectomies to the posterior chamber. The mean follow-up time was 25.3 months. AC hemorrhage occurred in five patients during the iridectomy procedure. Corneal edema was detected in eight of 14 patients with primary IOL insertions. Haptic dislocation was detected in only one patient. This technique may be a good alternative to scleral-fixated IOL implantation in eyes with aphakia.  相似文献

PURPOSE: To avoid anterior chamber lens implantation in aphakic eyes without capsular or zonular support, the laborious scleral fixation of a standard posterior chamber intraocular lens (IOL) is widely used, despite a large range of possible complications (macular edema, IOL tilt/decentration, suture erosion, vitreous hemorrhage). A sutureless iris-fixed ciliary sulcus implantation of a posterior chamber IOL (Binder-IOL, Fa. Iolution, Itzehoe) designed especially for such cases represents an alternative. METHOD: At the end of both haptics of this IOL, with a 6 mm optic zone, a T-shaped anchor is mounted at an angle of 45 degrees from the optical plane. These anchors are inserted from behind the iris into peripheral iridotomies performed preoperatively with a YAG-laser or intraoperatively with a vitrectomy cutter. The long, C-shaped haptics are thus secured in the ciliary sulcus. RESULTS: After slight modification of the technique, the implantation can be performed securely and reproducibly. In the 22 implantations performed to date, the IOL was well centered and stable, even in cases with only residual iris stroma. If the iridotomies are been performed too centrally, an ovalisation of the pupil may occur. No further side effects have been observed. CONCLUSION: The technique of sutureless sulcus fixation presented here leads to less complications than scleral suture fixation. A prerequisite for safe implantation of the anchors is good visibility of the peripheral iris. The implantation of the Binder-IOL is especially suitable for aphakic eyes with a loosened iris diaphragm.  相似文献

The aim of this study is to determine the effects of posterior chamber implantation on angle structures. First, without previous knowledge of the position of lens haptics, 360° gonioscopy was performed and any changes in the angle structures were recorded. Then, the pupil was dilated to determine the exact position of the intraocular lens haptics. The apposition of peripheral iris to angle structures or, at least, the narrowing of the angle corresponding to the lens haptic position was observed in almost all of the 117 examined eyes, with no difference found between bag and sulcus implantation. Peripheral anterior synechia overlying the lens haptic was observed in 49 (41.8%) of 117 eyes. Interestingly, we also noted that there was marked and well-limited clumping of pigment in the angle at 6 o'clock position in 67 (57.2%) of 117 eyes. In conclusion, we feel that posterior chamber intraocular lenses are not completely innocuous to the angle structures.  相似文献
