1/11. 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.

2/11. 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.

3/11. Anterior capsular phimosis in eyes with a capsular tension ring.

    A 64-year-old woman with zonular weakness in the left eye and a 79-year-old man with bilateral pseudoexfoliation and intraoperative zonular dehiscence had phacoemulsification with in-the-bag implantation of a single-piece poly(methyl methacrylate) intraocular lens (IOL) and a capsular tension ring. Ten to 12 weeks postoperatively, all 3 eyes developed significant visual loss secondary to capsule shrinkage and occlusion of the capsulorhexis opening. All eyes had a neodymium:YAG laser radial anterior capsulotomy, anterior capsulectomy, or both. visual acuity was restored in all eyes despite slight IOL decentration.

4/11. Combined strabismus and phacoemulsification cataract surgery: a useful option in selected patients.

    PURPOSE: To evaluate the role of combined strabismus and phacoemulsification cataract extraction in patients with symptomatic cataract and strabismus. methods: Four procedures of combined strabismus and cataract surgery are described in 3 elderly patients with strabismus of differing aetiologies. Two patients underwent one procedure; the other patient underwent two combined procedures, one to each eye. RESULTS: The visual acuity improved in all 3 patients. Post-operative alignment of the visual axis was achieved which allowed resolution of symptomatic diplopia in patient 1, functional binocular single vision in patient 2 and a noticeably reduced compensatory head posture in patient 3. CONCLUSIONS: Combined strabismus and cataract surgery is a safe procedure that can optimise visual alignment and improve visual acuity with a minimum number of operations.

5/11. Total encapsulation and asymmetric deformation of an intraocular lens.

    We report a case of marked anterior capsule contraction after uneventful cataract surgery in an 82-year-old women. The patient had implantation of a single-piece foldable acrylic intraocular lens (IOL) after phacoemulsification through a 3.0 mm superior corneal incision. Between 1 month and 5.5 months after surgery, significant anterior capsule contraction ensued with total encapsulation of the lens. The resultant fibrotic reaction, which had a localized tangential component, caused an asymmetric deformation and mild IOL displacement. The patient was treated on separate occasions with a neodymium:YAG laser anterior capsulotomy and surgical capsulotomy to release tension on the lens and clear the visual axis.

6/11. Single-piece hydrophobic acrylic intraocular lens explanted within the capsular bag: case report with clinicopathological correlation.

    A 74-year-old woman had uneventful phacoemulsification with implantation of a single-piece hydrophobic acrylic intraocular lens (IOL) (SA30AL) in her left eye. Two weeks after the surgery, the patient presented for ophthalmological consultation reporting pseudophakic dysphotopsia, which she had subjectively noted since surgery. Explantation/exchange of the IOL was performed 3 months after the surgery. The IOL was strongly attached to the capsule, which was fibrotic and contracted; explantation of the capsular bag complex in toto was done. To our knowledge, this is the first case of explantation of this IOL design with clinicopathological correlation.

7/11. Relaxing the fibrosed capsulorhexis rim to correct induced hyperopia after phacoemulsification.

    I present two cases in which hyperopia occurred after phacoemulsification through a capsulorhexis. In both eyes, the anterior capsule rim had become fibrosed and contracted. The patients were successfully treated with YAG laser relaxing incisions.

8/11. Total anterior capsule closure after silicone intraocular lens implantation.

    An 84-year-old man with a nuclear cataract had phacoemulsification, continuous curvilinear capsulorhexis, and implantation of a silicone intraocular lens. Two months later, the patient had vision loss and severe anterior capsule fibrosis, leading to complete posterior chamber lens encapsulation. After a capsular opening was created with a neodymium:YAG laser, visual acuity returned to the preoperative level of 20/30.

9/11. Posterior capsule rupture by blunt ocular trauma.

    A patient with posterior lens capsule rupture caused by blunt trauma and in whom the anterior capsule and the remainder of the eyeball structure was intact had phacoemulsification and aspiration of the crystalline lens with implantation of a posterior chamber intraocular lens. Further rupture of the capsule was prevented by the fibrosis, which tightened the margin of the ruptured capsule. This case shows that blunt trauma can rupture the posterior lens capsule, leaving the anterior capsule intact.

10/11. Silicone intraocular lens encapsulation by shrinkage of the capsulorhexis opening.

    We report a case of an 80-year-old woman who developed complete opacification and contraction of the continuous curvilinear capsulorhexis opening 4 months after having phacoemulsification and implantation of a silicone plate-haptic intraocular lens. We performed a neodymium:YAG laser capsulotomy without complication.
