11/66. Flexible iris hooks for phacoemulsification in patients with iridoschisis.

    Flexible iris hooks, or retractors, can be used to facilitate cataract removal by phacoemulsification in patients with primary iridoschisis. This rare condition is associated with fibrillary degeneration of the iris, narrow drainage angles, and cataract. In addition to their conventional use as iris retractors, iris hooks can control the degenerate fibrillary iris stroma to improve the view and access to the lens, preventing further damage during phacoemulsification and cortical cleanup. iris hooks are widely available, easily handled, and can transform a difficult case into one that is almost routine.

12/66. Cataract surgery and intraocular lens implantation in anterior megalophthalmos.

    Six eyes of 4 patients with anterior megalophthalmos, 2 men and 2 women ranging in age from 32 to 47 years, had extracapsular cataract extraction or phacoemulsification and standard posterior chamber intraocular lens implantation. All had a family history of anterior megalophthalmos. Follow-up was from 6 to 30 months. All patients had a preoperative visual acuity of worse than 20/60, which improved to 20/20 in 5 eyes. Zonular dehiscence was observed during surgery in 3 cases, leading to vitreous loss in 1 case that developed a retinal detachment after 3 months.

13/66. Spontaneous luxation of encapsulated intraocular lens onto the retina after a triple procedure of vitrectomy, phacoemulsification, and intraocular lens implantation.

    PURPOSE: To report the clinical and histological findings of a luxated intraocular lens (IOL) in the capsular bag. methods: review of a case. RESULTS: Twenty-three months after a triple procedure of vitrectomy, phacoemulsification, and IOL implantation for diabetic vitreous hemorrhage and cataract, the encapsulated IOL spontaneously luxated. Scanning electron microscopy showed sparsely distributed anterior and equatorial zonules, with only a few posterior zonules on the surface of the removed capusular bag. CONCLUSION: The absence of the anterior hyaloid membrane and posterior zonules and contraction of the lens capsule may cause dialysis of the zonules. Therefore, the anterior hyaloid membrane should be left in place in patients at low risk for the development of postoperative proliferation to maintain the long-term stability of the IOL.

14/66. Intraocular lens implantation in a child with monocular cataract and anterior persistent hyperplastic primary vitreous.

    A 3-year-old girl had phacoemulsification during which the presence of anterior persistent hyperplastic primary vitreous (PHPV) was discovered. Visual rehabilitation comprised contact lens use for 1 year. However, visual acuity deteriorated gradually because of secondary cataract formation. In a second surgery 1 year after the first, the posterior capsule was incised, followed by an anterior vitrectomy and intraocular lens implantation. At the last follow-up 6 months after the second surgery, there was no evidence of ocular complications and best corrected visual acuity was 0.6.

15/66. Transient intraocular pressure elevation after trabeculotomy and its occurrence with phacoemulsification and intraocular lens implantation.

    PURPOSE: To elucidate the characterization of intraocular pressure (IOP) spike after trabeculotomy, and after the combined procedure of phacoemulsification and aspiration (PEA) and intraocular lens (IOL) implantation. methods: Included in this study were 39 patients (53 eyes) with primary open-angle glaucoma with IOPs uncontrolled even with anti-glaucoma medication. We conducted a retrospective study for the following two groups: patients who underwent trabeculotomy alone (25 eyes) and patients undergoing trabeculotomy combined with PEA and implantation of an IOL (28 eyes). RESULTS: In 7 (28%) of the 25 eyes after trabeculotomy alone and 7 (25%) of the 28 eyes after the combined procedure, transient IOP elevation was found postoperatively. The incidence of hyphema-related IOP spike was significantly higher in eyes after trabeculotomy alone (16%) than after the combined procedure (0%). After removal of the blood present in the anterior chamber in eyes with hyphema-related IOP spikes, the IOP levels were well controlled. CONCLUSIONS: hyphema-related IOP spike is one of the common complications in eyes after trabeculotomy alone, and the combined procedure decreases the incidence of this complication. It is thought that removal of prolonged massive hyphema is effective as treatment for hyphema-related IOP spike.

16/66. ciliary body tumor and cataract: local resection combined with phacoemulsification.

    A 57-year-old man developed a ciliary body mass, clinically diagnosed as malignant melanoma of the ciliary body, that produced a cataract in the right eye. Treatment was cataract surgery with sclerouvectomy performed simultaneously. Pathohistologic examination revealed an acquired adenoma of the nonpigmented ciliary epithelium. The clinicopathologic features and treatment of this tumor are discussed.

17/66. Comparison of Scheimpflug images of posterior capsule opacification and histological findings in rabbits and humans.

    PURPOSE: To compare the posterior capsule opacification in Scheimpflug photographic images produced by an electronic anterior eye segment analysis system with the histopathological findings in rabbits and humans. SETTING: Department of ophthalmology, Wakayama Medical College, japan. methods: Opacified posterior capsules were photographed using the EAS-1000 system (Nidek) and were then extracted during vitreous surgery for proliferative diabetic retinopathy or proliferative vitreoretinopathy in 2 patients. In rabbits, phacoemulsification and aspiration (PEA) with intraocular lens (IOL) implantation was performed. The IOL was implanted in the bag or in the sulcus. After intervals of healing, the posterior capsule was photographed with the EAS-1000 and the animals were then killed. In both clinical and experimental specimens, the posterior capsule was processed for light microscopic histology and immunohistochemistry. RESULTS: Opacified human capsules were well imaged by the EAS-1000. histology showed that lens epithelial cells proliferated with and without an accumulation of extracellular matrix. Details such as rolling of the capsulotomy edge were seen well. Regenerated lens fibers of Soemmering's ring were seen as a mass within the capsule. In the rabbit model, Scheimpflug images accurately represented the capsules as they appeared histologically. CONCLUSION: The EAS-1000 system provided faithful, relatively high-resolution images that corresponded to the histologic findings in the posterior capsules after PEA-IOL surgery in humans and rabbits.

18/66. rupture of a radial keratotomy incision after 11 years during clear corneal phacoemulsification.

    We report a case of rupture of a radial keratotomy (RK) incision that occurred during clear corneal phacoemulsification 11 years after the initial surgery. The RK was done in both eyes for correction of high myopia (>8.0 diopters). This was followed by 2 enhancement procedures at 6 month intervals. The patient presented with diminished vision in both eyes. The diagnosis was nuclear cataract in the right eye, and clear corneal phacoemulsification was done. The intraoperative and postoperative courses were uneventful. Nine months later, clear corneal temporal phacoemulsification was done in the left eye. During surgery, 1 of the radial incisions opened to one third its length. The wound was sutured, and the procedure was completed uneventfully. One month later, best corrected visual acuity was 20/20.

19/66. Cataract surgery in patients with advanced Mooren's ulcer.

    BACKGROUND: We describe 2 patients with severe Mooren's ulcer who underwent phacoemulsification and intraocular lens implantation surgery. The clinical features of this disease are highlighted. CASE: A detailed study of the ocular and laboratory findings in these patients, together with a review of the literature, is presented. OBSERVATIONS: There was a visually rewarding outcome after phacoemulsification and intraocular lens implantation were performed, and Mooren's ulcer did not recur. CONCLUSION: We conclude that phacoemulsification-aspiration and intraocular lens implantation surgery with a small incision can be successfully performed in patients with Mooren's ulcer after complete control of inflammation with topical and oral steroid therapy, or with ocular reconstruction surgery when required.

20/66. 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.
