1/94. Complete occlusion of the anterior capsular opening after intact capsulorhexis: clinicopathologic correlation.PURPOSE: To report histopathologic findings of capsule contraction syndrome with complete occlusion of the capsulorhexis opening. methods: Case report. In an 81-year-old woman, a complete occlusion of the anterior capsulorhexis opening developed 2 months after phacoemulsification and intraocular lens implantation. We surgically removed the contracted anterior capsule and analyzed the membrane by standard light microscopy and actin immunohistology. RESULTS: light microscopic analysis of the membrane showed fibrous tissue subcapsularly with metaplastic lens epithelial cells. The contracted capsulorhexis opening was filled completely with proliferated actin-positive lens epithelial cells. CONCLUSIONS: Complete occlusion of the capsulorhexis opening can be attributed to excessive shrinkage of the capsule, probably caused by actin filaments found in the residual lens epithelial cells together with weak zonular support, and to the occlusion of the remaining central defect by massive proliferation of metaplastic lens epithelial cells.- - - - - - - - - - ranking = 1keywords = capsule (Clic here for more details about this article) |
2/94. Lens opacity after neodymium: YAG laser iridectomy for phakic intraocular lens implantation.We describe a previously unreported complication of a posterior chamber intraocular lens (IOL) implanted in a phakic eye. The left eye of a 25-year-old patient with high myopia was treated prophylactically with neodymium: YAG (Nd: YAG) laser iridotomy prior to phakic IOL implantation. Slitlamp examination of the left eye disclosed an opacity of the anterior capsule of the crystalline lens under the iridotomy site. This case demonstrates a complication associated with Nd:YAG iridotomy prior to implantation of a phakic IOL.- - - - - - - - - - ranking = 0.33333333333333keywords = capsule (Clic here for more details about this article) |
3/94. Posterior capsule opacification and wrinkling in a case of capsular bag distension.We describe a complication following anterior neodymium: YAG laser capsulotomy in a case of capsular bag distension which was diagnosed 21 months after cataract extraction with phacoemulsification and in-the-bag lens implantation. An anterior neodymium: YAG capsulotomy was performed and immediately after this the posterior capsule collapsed and wrinkled, causing a marked decrease in visual acuity that necessitated posterior neodymium: YAG capsulotomy.- - - - - - - - - - ranking = 1.6666666666667keywords = capsule (Clic here for more details about this article) |
4/94. cataract extraction and intraocular lens implantation in anterior megalophthalmos.This report describes the implantation of a standard posterior chamber intraocular lens (IOL) in a patient with bilateral cataract and anterior megalophthalmos. After extracapsular cataract extraction, the IOL was sutured to the posterior surface of the iris and anterior capsule. Different types of IOLs were used in each eye, and the surgical technique was adapted to the characteristics of the IOL. No complications were noted. Visual rehabilitation was successful. Extracapsular cataract extraction with a posterior chamber IOL sutured to the posterior surface of the iris and anterior capsule is a useful option in patients with anterior megalophthalmos and cataract.- - - - - - - - - - ranking = 0.66666666666667keywords = capsule (Clic here for more details about this article) |
5/94. Complete capsulorhexis opening occlusion despite capsular tension ring implantation.An 89-year-old woman and an 86-year-old woman had continuous curvilinear capsulorhexis, phacoemulsification, and implantation of a silicone plate-haptic intraocular lens. Because of presumed weak zonules (high age, pseudoexfoliation), a poly(methyl methacrylate) capsular tension ring was also implanted. Despite this, both patients reported deterioration in visual acuity that was the result of complete occlusion of the anterior capsule opening by fibrotic tissue 4 and 3 months postoperatively, respectively.- - - - - - - - - - ranking = 0.33333333333333keywords = capsule (Clic here for more details about this article) |
6/94. Spontaneous absorption of a cataractous lens.A case of spontaneous absorption of a cataractous lens is presented. A 37-year-old woman with Down's syndrome presented with bilateral cataracts. On follow-up, the cataract in her right eye was found to be absorbed with no secondary uveitis or glaucoma. Surgical capsulotomy was performed on the remnant anterior and posterior capsules. Such absorption is known in juveniles and in hypermature cataract, but is rare in adults in the absence of injury or inflammation. absorption occurred over a period of one year.- - - - - - - - - - ranking = 0.33333333333333keywords = capsule (Clic here for more details about this article) |
7/94. In-the-bag secondary intraocular lens implantation in children.BACKGROUND: Surgery for congenital cataracts in early infancy usually includes a primary posterior capsulectomy and an anterior vitrectomy. Initially, most of these infants have aphakia after surgery. Over time, remaining equatorial lens epithelial cells produce new cortical fibers, resulting in a ring of cortex trapped between the lens equator and the fused anterior and posterior capsulectomy edges. A potential space is maintained between the anterior and posterior capsular leaflets. We describe a technique for placing a secondary intraocular lens (IOL) within the capsular bag. patients AND methods: Eight children, ranging in age from 11 months to 14 years, who originally had aphakia after cataract extraction were operated on with the intent to reopen the capsular bag and place an IOL in the bag. RESULTS: Secondary in-the-bag IOL implantation was successfully completed in 7 of 8 children. This was accomplished by reopening the capsular bag 360 degrees at the edge of the fused anterior and posterior capsulectomy remnants, using the previously published vitrectorhexis technique. Residual cortical material was aspirated, and an IOL was placed within the capsular bag. In 1 child, aged 14 years, the capsular bag was reopened, but the lens was placed in the ciliary sulcus because the new anterior capsule edge could not be visualized for 360 degrees . CONCLUSION: Placement of secondary IOLs within the capsular bag can be accomplished successfully for selected patients in the pediatric population. Surgeons operating on infantile cataracts without primary IOL placement can facilitate capsular IOL sequestration later by limiting the anterior and posterior capsulectomy to 4 to 5 mm and performing a generous anterior vitrectomy to help prevent secondary closure of the smaller capsulectomy.- - - - - - - - - - ranking = 2keywords = capsule (Clic here for more details about this article) |
8/94. rupture of the anterior lens capsule in Alport syndrome.Alport syndrome is an inherited disorder of type IV collagen, a major constituent of basement membranes. Eighty-five percent of cases are transmitted through X-linked dominant inheritance, although autosomal dominant and autosomal recessive inheritance has also been reported. Clinical manifestations of Alport syndrome include progressive glomerulopathy, sensorineural deafness, anterior lenticonus, posterior corneal dystrophy, and abnormal retinal pigmentation. Anterior lenticonus may lead to loss of vision because of progressive myopia or cataract formation. We report 2 cases of unusual cataract formation in adolescent boys who had a rupture of the anterior lens capsule. One rupture was spontaneous, and the other was traumatic.- - - - - - - - - - ranking = 1.6666666666667keywords = capsule (Clic here for more details about this article) |
9/94. Truncated edge design, dysphotopsia, and inhibition of posterior capsule opacification.A 73-year-old woman had implantation of a silicone intraocular lens (IOL) with a truncated edge design. Like some other patients with acrylic IOLs, she experienced long-term undesirable reflections and halos. However, the posterior capsule remained clear. The fellow eye had a different style silicone IOL, which induced no visual side effects but was associated with early posterior capsule opacification.- - - - - - - - - - ranking = 2keywords = capsule (Clic here for more details about this article) |
10/94. Spontaneous regression of Elschnig pearl posterior capsule opacification.After extracapsular cataract extraction with in-the-bag intraocular lens implantation, a 72-year-old woman had reduced visual acuity from posterior capsule opacification (PCO) resulting from Elschnig pearl proliferation. No capsulotomy was performed, and the PCO decreased spontaneously over time, improving visual acuity and leaving a clear capsule.- - - - - - - - - - ranking = 2keywords = capsule (Clic here for more details about this article) |
