Morphological changes 2 1/2 years after extracapsular cataract extraction with implantation of a posterior chamber lens. A prospective re-examination

Morphological changes and lens position were examined in 51 eyes of 51 patients 25 to 37 (mean 31) months after extracapsular cataract extraction with implantation of a posterior chamber lens in the ciliary sulcus. Ocular morphology was compared to a previously published examination of the same eyes performed 4 months after surgery. The anterior chamber depth, lens position and the position of the posterior lens capsule had remained unchanged. 'Iris bulging', i.e. a gonioscopically visible slight impression of the iris overlying the lens haptics, had increased from 0 to 42%, iridal transillumination defects from 34 to 46%, and pigment dispersion in the chamber angle from 46 to 72%. Twenty-four percent of the eyes had developed significant, capsulotomy-requiring opacification of the posterior lens capsule. We draw the following conclusions: The posterior chamber lens and the posterior lens capsule have reached their permanent positions by the fourth post-operative month. Implantation of a posterior chamber lens in the ciliary sulcus constitutes a constant stimulus for structural changes of the iris with subsequent dispersion of pigment on neighbouring ocular structures.     

Visual results and postoperative complications of capsular bag and ciliary sulcus fixation of posterior chamber intraocular lenses in children with traumatic cataracts

PURPOSE: To evaluate the visual results and postoperative complications of capsular bag and ciliary sulcus fixation of posterior chamber intraocular lenses (IOLs) for traumatic cataracts in children. SETTING: Department of Ophthalmology, Postgraduate Institute of Medical Education and Research, Chandigarh, India. METHODS: Twenty children (20 eyes) with traumatic cataracts had extracapsular cataract extraction (ECCE) and posterior chamber IOL implantation. They were randomly divided into 2 groups. Capsular bag fixation was performed in 10 children (Group A) and ciliary sulcus fixation in the other 10 (Group B). Traumatic cataracts associated with large corneal lacerations (10.0 mm or more), hyphema, angle recession, or posterior segment involvement were excluded. The best corrected visual acuity (BCVA) as well as early and delayed postoperative complications were prospectively evaluated in both groups. RESULTS: The BCVA was 6/12 or better in 9 eyes (90%) in Group A and 8 eyes (80%) in Group B at the end of the mean follow-up (24.6 months +/- 10.6 [SD]). Amblyopia (1 eye in Group A) and corneal scar and commotio retinae (1 eye each in Group B) accounted for a visual acuity of worse than 6/12. The residual refractive error did not exceed 3.50 diopters in either group. The incidences of fibrinous anterior uveitis and pupillary capture were significantly higher in Group B (P < .05, Fisher exact test). CONCLUSION: Capsular bag fixation of posterior chamber IOLs provided visual results similar to those with ciliary sulcus fixation but was associated with fewer postoperative complications, particularly uveitis and pupillary capture. This represents another important reason to attempt in-the-bag fixation in cases of traumatic cataract.     

玻璃体切除联合晶体超声碎核术治疗晶体半脱位合并葡萄膜炎

目的：探讨玻璃体切除联合晶体超声碎核术治疗晶体半脱位合并葡萄膜炎的临床治疗效果。方法：对我院1998年6月至2001年12月期间共收治的9例(11眼)晶体半脱位合并葡萄膜炎的患者行玻璃体切除联合晶体超声碎核术，其中7例(9眼)未I期植入人工晶体，另2例(2眼)植入缝线型人工晶体，术后随访3个月到24个月，观察术后视力及并发症等。结果：术后3月所有患者最佳矫正视力均有不同程度的提高，其中≥0．6的6眼，0．3～0．6的3眼，另2眼最佳矫正视力0．1～0.3；术后并发症有手术后一周内前房的纤维索性渗出4例(5眼)，经药物治疗后很快吸收；术后复发性葡萄膜炎2例(2眼)均为植入缝线型人工晶体眼，药物治疗效果不佳。结论：玻璃体切除联合晶体超声碎核术是治疗晶体半脱位合并葡萄膜炎最为安全和有效的治疗方法，术后并发症少，视力恢复满意，但I期植入缝线型人工晶体可能导致葡萄膜炎复发。     

后房型人工晶状体后脱位的临床分析

目的：探讨后房型人工晶状体后脱位发生的原因及处理方法。方法：对6例后房型人工晶状体后脱位患者临床资料，进行回顾性复习，以发现其发生原因及最佳处理方法。其发生原因与摘出白内障术中晶状体后囊破裂或悬韧带严重损伤有关。对6例患者中5例，采用玻璃体切除及睫状沟缝线固定术；1例观察。结果 4例人工晶状体复位成功，裸眼视力0．3～0．8。1例并发眼内炎再次取出人工晶状体，观察的1例矫正视力0．6。结论：后房型人工晶状体后脱位与后囊膜破裂有关，玻璃体手术及睫状沟缝线固定可以使人工晶状体复位，提高视力。注意防止眼内炎。

Phacoemulsification cataract extraction and posterior chamber lens implantation in patients with uveitis

PURPOSE: This study reports outcomes of phacoemulsification cataract extraction and posterior chamber intraocular lens implantation within the capsular bag in patients with uveitis. METHODS: We retrospectively reviewed the charts of 32 patients (39 eyes) with uveitis who underwent phacoemulsification cataract extraction and posterior chamber intraocular lens implantation by two surgeons at The Cleveland Clinic Foundation from January 1990 to June 1998. Patients with less than 3 months of follow-up were excluded. RESULTS: Diagnoses of uveitis included idiopathic (15 eyes), sarcoidosis (10 eyes), pars planitis (four eyes), CMV retinitis (two eyes), Fuchs heterochromic iridocyclitis (two eyes), syphilis (two eyes), and one eye each of tuberculosis, Crohn's disease, HLA-B27 associated, and acute retinal necrosis. Average follow-up was 20 months (range, 3 to 63 months). Best-corrected visual acuity improved in 37 eyes (95%). Average improvement was 4 +/- 3 Snellen acuity lines (range, 1 to 10 lines). Thirty-four eyes (87%) attained final visual acuity better than or equal to 20/40. Visual loss occurred in one eye (3%) with CMV retinitis. No improvement in visual acuity was seen in one eye (3%) that developed a retinal pigment epithelial detachment. Posterior capsule opacification occurred in 24 eyes (62%), 12 of which required Nd:YAG capsulotomy (31%). Other postoperative complications included recurrence of uveitis (41%), cystoid macular edema (33%), epiretinal membrane formation (15%), and posterior synechiae (8%). CONCLUSIONS: Phacoemulsification cataract extraction with posterior chamber intraocular lens implantation is safe in patients with uveitis. The incidences of recurrence of uveitis, cystoid macular edema, epiretinal membrane, and posterior synechiae were lower than those reported previously for extracapsular cataract extraction.     

Comparison of Artisan iris-claw intraocular lens implantation and posterior chamber intraocular lens sulcus fixation for aphakic eyes

AIM: To compare the efficacy and complications of Artisan iris-claw intraocular lens (IOL) implantation and posterior chamber IOL sulcus fixation for the treatment of aphakic eyes without capsular support after vitrectomy.METHODS:A prospective study of 45 cases was conducted. Forty-five eyes without sufficient lens capsule support following pars plana vitrectomy (PPV) combined lens extraction were divided into two groups. Group A:25 eyes received Artisan iris-claw IOL implantation. Group B:20 eyes received posterior chamber IOL sulcus fixation. The corrected distance visual acuity (CDVA) and intraocular pressure (IOP), corneal endothelial cell loss rate, surgical time and complications were compared between the two groups. Pigment changes of trabecular meshwork and anterior chamber depths were measured at each time point in Artisan group.RESULTS:The mean surgical time of Artisan group was significantly shorter (P<0.05). No statistically significant difference in endothelial cell loss rate was noted between two groups at any time point (P>0.05). CDVA of Artian group was better than that of the sulcus fixation group 1d after surgery (P<0.05) and there was no statistically significant difference 1 and 3mo after surgery (P>0.05). Mean IOP showed no significant differences between groups before and after surgery. The postoperative complications of Artisan group were anterior uveitis, iris depigmentation, pupillary distortion and spontaneous lens dislocation. The complications of sulcus fixation group include choroidal detachment, intraocular haemorrhage, tilt of IOL optic part and retinal detachment.CONCLUSION:Secondary Artisan IOL implantation can be performed less invasively and in a shorter surgical time period with earlier visual recovery after surgery compared to transscleral suturing fixation of an IOL. This technique is an effective and safe procedure. It is a promising option for the treatment of aphakic eyes without capsular support after vitrectomy.

Ultrasound biomicroscopy in uveitis-glaucoma-hyphema syndrome

PURPOSE: To assess anterior segment anatomy in uveitis-glaucoma- hyphema syndrome. DESIGN: Retrospective case series. METHODS: Nine pseudophakic eyes (nine patients) with complete or incomplete uveitis-glaucoma-hyphema syndrome underwent ultrasound biomicroscopy. RESULTS: Ultrasound biomicroscopy revealed intraocular lens malposition in each case. Of the eight eyes with posterior chamber intraocular lenses, haptics were in contact with the iris pigment epithelium (four eyes) or the pars plicata (three eyes) or prolapsed into the angle recess near a filtration bleb internal ostium (one eye). All other posterior chamber intraocular lens haptics were located in the ciliary sulcus with the exception of two in the capsular bag. Both haptics in the eye with the anterior chamber intraocular lens had eroded into the ciliary body. CONCLUSION: By its ability to detect haptic position, ultrasound biomicroscopy can assist in elucidating the cause of uveitis-glaucoma-hyphema syndrome and in deciding on the course of treatment.
