1/18. 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.

2/18. phacoemulsification in spherophakia with corneal touch.

    A phacoemulsification procedure with implantation of a foldable acrylic intraocular lens in a 31-year-old man with spherophakia is described. The procedure was necessitated by anterior dislocation of the spherophakic lens, with corneal endothelial contact and development of central corneal edema. With a careful approach, the procedure was uneventful and the outcome successful. Modern small-incision cataract surgery techniques are of great benefit in this type of complicated case.

3/18. Scheimpflug imaging of bilateral foldable in-the-bag intraocular lens implantation assisted by a scleral-sutured capsular tension ring in Marfan's syndrome.

    A 35-year-old white man with bilateral high myopia, astigmatism, subluxated crystalline lenses, and incipient cataract had phacoemulsification and implantation of a hydrophobic acrylic intraocular lens (IOL) (Alcon MA60BM) in both eyes. The subluxated capsular bag was stabilized and recentered using a scleral-fixated capsular tension ring (CTR) (type 1L, Morcher). Measured with Scheimpflug photography, the capsular bag and IOL were in a stable intraocular position during the 18-month follow-up. There were no major changes in refraction. Despite the sharp-edged IOL design, both eyes had posterior capsule opacification (PCO) 18 months after surgery that in 1 eye caused a decrease in visual acuity of more than 2 lines. High myopia and subluxated lenses may be treatable long-term with a scleral-fixated CTR and foldable IOL implantation; further evaluation of PCO is necessary.

4/18. Long-term complications of bilateral posterior chamber phakic intraocular lens implantation.

    A 34-year-old woman had posterior chamber phakic intraocular lens (PCP IOL) implantation to correct high myopia in both eyes. Five years postoperatively, the patient presented with a decrease in visual acuity from central anterior subcapsular cataract formation in both eyes and IOL dislocation in the left eye. In vivo confocal microscopy of the cornea showed markedly decreased endothelial cell density in both eyes and the presence of bright endothelial microdeposits possibly related to pigmentary dispersion. gonioscopy showed angle pigmentary deposits with no intraocular pressure increase. The patient was successfully treated by removing the PCP IOLs and performing phacoemulsification with in-the-bag IOL implantation in both eyes. This led to a recovery of visual acuity. This case report presents the rare occurrence and surgical management of cataract formation, IOL dislocation, and severe endothelial cell loss as a late complication of PCP IOL implantation.

5/18. Long-term observation of the refraction with a reversed-optic posterior chamber intraocular lens.

    A 73-year-old man had phacoemulsification and implantation of a posterior chamber intraocular lens (PC IOL) in both eyes. In the right eye, the optic was unintentionally reversed in the bag. In the left eye, the posterior capsule was ruptured and the IOL haptics were fixated in the ciliary sulcus. The refraction in the sulcus-fixated left eye was stable from 1 month to 4 years. The right eye had a myopic shift at 1 month, with a regression of 1.50 diopters that continued for 2 years. The final IOL position in the right eye was 0.25 mm anterior to the position predicted by the SRK/T formula. It took 2 years for the refraction in the eye with the reversed-optic PC IOL to become stable. A large myopic shift and gradual regression in refraction may stem from a different wound-healing reaction than that of properly fixated IOLs.

6/18. Lenticular myopia from oil-drop cataract: a cautionary note in laser in situ keratomileusis.

    We present 5 patients with oil-drop cataracts in whom the underlying lenticular cause of myopic regression after laser in situ keratomileusis (LASIK) had been missed by their ophthalmologists. As a result, the patients were scheduled for or had had LASIK enhancement before presentation to us. After oil-drop cataracts were diagnosed, phacoemulsification was performed successfully in at least 1 eye of all patients. These cases underscore the importance of considering lens-induced myopia in refractive surgery patients, especially those with an unstable preoperative refraction or postoperative myopic regression. Refractive surgery in these cases can unnecessarily complicate the measurement of intraocular lens strength in cataract surgery.

7/18. Capsular bag distension syndrome after combined cataract and glaucoma surgery.

    PURPOSE: To report four cases of capsular bag distension syndrome (CBDS) after combined cataract and glaucoma surgery. methods: We describe the clinical features and evolution of each case after individual treatment. case reports: We report four cases of CBDS after phacoemulsification, combined with trabeculectomy in two cases and with an Ahmed aqueous drainage device implantation in the other two cases. The space between the intraocular lens (IOL) and the posterior capsule was occupied by an optically clear liquid in two cases and by a turbid liquid in the other two cases, with posterior bowing of the capsule into the anterior vitreous. A myopic shift and anterior chamber shallowing occurred in three cases. After posterior Nd:YAG laser capsulotomy, the CBDS resolved in three cases. In case 1, a surgical posterior capsulotomy and anterior vitrectomy were necessary. DISCUSSION: Capsular bag distension syndrome should be included in the differential diagnosis of a shallow anterior chamber after combined cataract and glaucoma surgery.

8/18. Accurate intraocular lens power calculation after myopic laser in situ keratomileusis, bypassing corneal power.

    PURPOSE: To describe a novel method for calculating intraocular lens (IOL) power after myopic laser in situ keratomileusis (LASIK) without using the inaccuracies of the post-LASIK corneal power. SETTING: Department of ophthalmology, Wake Forest University eye Center, Wake Forest University School of medicine, Winston Salem, north carolina, USA. methods: This retrospective chart review comprised 9 eyes of 9 patients who had phacoemulsification after LASIK using our method for IOL calculation. This new method assumes the patient never had myopic LASIK to calculate IOL power and then targets the IOL at the pre-LASIK amount of myopia. The pre-LASIK keratometry values, pre-LASIK manifest refraction, and the current axial length are placed in the Holladay formula, bypassing the post-LASIK corneal power. In theory, assuming that the patient had satisfactory LASIK results, the correct IOL can then be determined. RESULTS: The mean spherical equivalent postoperative refraction was 0.03 diopter (D) /- 0.42 (SD) (range -0.625 to 0.75 D). In all 9 eyes, our method consistently chose the most accurate and precise IOL compared with other methods. CONCLUSIONS: The new method of calculating IOL power after LASIK provided excellent results and the most accurate and precise results to date.

9/18. choroidal neovascularization in highly myopic eyes after cataract surgery.

    PURPOSE: To determine the incidence and characteristics of choroidal neovascularization (CNV) in patients with high myopia (>or=8 diopters) who underwent cataract surgery in the Department of ophthalmology, tokyo Medical and Dental University, or the Ohno eye Clinic, tokyo, between September 1991 and March 2000. methods: The medical records of 35 patients (48 eyes) who underwent cataract surgery with phacoemulsification and intraocular lens implantation were studied retrospectively. The development of CNV over a 4-year follow-up period, and its characteristics were determined. All of the eyes had received a comprehensive ophthalmological examination, including best-corrected visual acuity measurements, anterior segment biomicroscopy, and a dilated fundus examination by stereoscopic observation. RESULTS: CNV was found in six eyes (12.5%) of six patients. The mean interval between cataract surgery and the development of CNV was 34 /-17 months (range, 12-48 months). The CNV was subfoveal in all cases. The mean logarithm of the minimum angle of resolution (logMAR) after cataract surgery and before the appearance of CNV was 0.23 /-0.24, and 0.93 /-0.41 after the CNV appeared. This decrease was statistically significant (P=0.0008, paired Student t test). Subfoveal CNV developed more frequently in eyes when the fellow eye showed evidence of CNV preoperatively (40.0%) than in eyes when the fellow eye exhibited no evidence of CNV (9.3%). CONCLUSIONS: CNV developed in 12.5% of patients with high myopia after cataract surgery. CNV tended to develop more frequently when the fellow eye had CNV.

10/18. 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.
