1/8. Managing anterior capsule contraction by mechanical widening with vitrector-cut capsulotomy.

    We present a technique, vitrectorhexis, in which a vitrector-cut capsulotomy is used to treat anterior capsule contraction syndrome. A vitrector handpiece is used to remove all fibrous capsule tissue and residual lens epithelial cells from the anterior chamber. Vitrectorhexis may be an alternative to neodymium:YAG laser capsulotomy as it decreases the risk of radial tear extension to the zonules and of secondary IOL decentration. The technique was used in a 77-year-old man with capsulorhexis contraction syndrome and extensive fibrosis after phacoemulsification with silicone piggyback intraocular lens implantation. One day postoperatively, visual acuity improved from 20/60 to 20/30 and the anterior chamber reaction was minimal. At 1 month, best corrected visual acuity was 20/20. The IOL was well centered at 6 months.

2/8. Complete anterior capsule contraction after phacoemulsification with acrylic intraocular lens and endocapsular ring implantation.

    A 69-year-old man with pseudoexfoliation syndrome and bilateral cataract had phacoemulsification with continuous curvilinear capsulorhexis and implantation of a morcher endocapsular ring and AcrySof acrylic intraocular lens (IOL) (Alcon). Two months later, the patient had vision loss in the left eye with a visual acuity of 20/500. He presented with anterior capsule fibrosis in both eyes, with complete occlusion of the capsule opening in the left eye and mild occlusion in the right eye. After a neodymium:YAG laser anterior capsulotomy in the left eye, visual acuity was 20/20. This case shows that endocapsular ring implantation does not prevent anterior capsule contraction syndrome but can prevent IOL decentration.

3/8. 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.

4/8. Capsular peeling in anterior capsule contraction syndrome: surgical approach and histopathological aspects.

    We present 4 cases of anterior capsule contraction syndrome in which progressive shrinkage of the anterior capsulorhexis developed after uneventful phacoemulsification. Three eyes were pseudophakic, and 1 eye remained aphakic. The newly formed membrane was surgically peeled from the anterior capsule, restoring the capsular bag.

5/8. Choroidal effusion and hypotony caused by severe anterior lens capsule contraction following cataract surgery.

    PURPOSE: The case report describes a case of severe anterior capsular contraction associated with choroidal effusion. CASE REPORT: An 81 year old female with primary open angle glaucoma underwent routine phacoemulsification cataract surgery. Eight weeks following surgery the anterior capsule opening had reduced to 3 mm in size. intraocular pressure was found to be 4 mmHg and B scan ultrasound revealed a large choroidal effusion. Anterior capsulotomy with Nd:YAG laser was performed. At review, two weeks later, the choroidal effusion had resolved and visual acuity had recovered. DISCUSSION: The Nd:YAG laser radial relaxing capsulotomies helped relieve the capsular contraction and associated traction on the ciliary body.

6/8. capsulorhexis contracture in phacoemulsification surgery.

    We report two cases of capsulorhexis contracture and eventual complete closure after phacoemulsification surgery. The closures significantly decreased vision, but vision improved in both cases following successful Nd:YAG laser treatment.

7/8. Capsule contraction after continuous curvilinear capsulorhexis.

    We report two cases of capsular bag contraction that occurred within 1 month after continuous curvilinear capsulorhexis, phacoemulsification, and intraocular lens implantation. Neither patient had a known risk for this complication. Both patients had a neodymium:YAG laser anterior capsulotomy, which disrupted the capsulorhexis margin and led to prompt capsular bag distension.

8/8. Severe capsulorhexis contracture after cataract surgery in myotonic dystrophy.

    A 42-year-old woman with myotonic dystrophy developed bilateral severe capsulorhexis contracture after uneventful phacoemulsification cataract surgery with implantation of 1-piece poly(methyl methacrylate) intraocular lenses (IOLs). The anterior capsular opening in her right eye constricted to a diameter of 0.7 mm, reducing visual acuity to counting fingers. Complete closure of the capsulorhexis with IOL encapsulation developed in her left eye, reducing visual acuity to hand movements. Surgical anterior capsulectomies restored visual acuity to 6/9 in both eyes. myotonic dystrophy may predispose to the development of severe capsulorhexis contracture after cataract surgery.
