1/7. Pigment dispersion with elevated intraocular pressure after AcrySof intraocular lens implantation in the ciliary sulcus.

    A 45-year-old white woman had phacoemulsification with intraocular lens (IOL) implantation. The surgery was routine except for a linear tear in the posterior capsule; there was no disruption of the anterior vitreous face. After residual soft lens matter was removed, an AcrySof IOL was placed in the ciliary sulcus. One month postoperatively, the patient presented with an intraocular pressure (IOP) of 30 mm Hg and signs of pigment dispersion with 360 degrees of heavy pigmentation of the trabecular meshwork and iris transillumination defects. intraocular pressure was controlled with a topical beta-blocker. The optic disc appearance and visual field remained normal, but the uniocular hyperpigmentation of the trabecular meshwork was still present. We hypothesize that the sharp square edge of the AcrySof IOL increases the risk of a chafing effect on the posterior iris pigment and advocate that this IOL be placed in the capsular bag and ideally have 360 degrees of protective overlapping of the anterior capsule over the edge of the optic.

2/7. 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.

3/7. 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.

4/7. Late complications with intraocular lens dislocation after capsulorhexis in pseudoexfoliation syndrome.

    We report 3 cases of significant late intraocular lens/capsular bag subluxation after uneventful capsulorhexis, endolenticular phacoemulsification, and capsular bag implantation in patients with pseudoexfoliation syndrome.

5/7. Posteriorly dislocated capsular tension ring.

    A 69-year-old man who had pseudoexfoliation and significant nuclear cataract underwent cataract surgery in his right eye. At the beginning of the phacoemulsification, inferior zonulolysis was observed and a capsular tension ring was implanted. Anterior vitrectomy was also performed because of vitreous in the anterior chamber at the end of surgery. A tear in the posterior capsule could not be identified. Three days after surgery, the capsular tension ring was observed partially in the anterior vitreous. A 3-port pars plana vitrectomy was performed and the ring was removed. Three weeks later, the eye developed retinal detachment and was successfully repaired. Retinal complications can develop if the capsular tension ring moves into the vitreous.

6/7. Anterior segment imaging using optical coherence tomography and ultrasound biomicroscopy in secondary pigmentary glaucoma associated with in-the-bag intraocular lens.

    A 43-year-old man with high myopia developed unilateral pigmentary glaucoma with recurrent episodes of painless blurred vision in the left eye following uneventful phacoemulsification. Bilateral cataract surgery was performed with capsular bag implantation of a 4.00 diopter AcrySof MA60 intraocular lens (IOL) (Alcon laboratories) followed by a neodymium:YAG laser capsulotomy. Secondary iatrogenic dispersion syndrome in the left eye with subsequent intraocular pressure elevation was suspected in the presence of anterior chamber pigmented cells, circular epithelial iris loss around the pupil, and trabecular hyperpigmentation. Close contact between the edge of the IOL and the posterior pigmented iris epithelium, which was clinically suggested by anterior biomicroscopy, was documented by ultrasound biomicroscopy and optical coherence tomography of the anterior segment.

7/7. Recurrent severe hypotony after cataract surgery in an eye with previous trabeculectomy.

    This report describes a patient who developed severe recurrent hypotony after uneventful phacoemulsification and intraocular lens (IOL) implantation 4 years after trabeculectomy. Hypotony was first noticed 1 month postoperatively and treated successfully with topical steroids. However, it reappeared 2 months later and slowly subsided only with steroid and cycloplegic treatment. There was no anterior chamber shallowing, leakage, or signs of inflammation. The cause of hypotony in this patient remains unknown. One possible explanation is subclinical postoperative inflammation as a foreign-body reaction to the IOL.
