Clinical Outcomes and Cataract Formation Rates in Eyes 10 Years After Posterior Phakic Lens Implantation for Myopia.

Intraocular collamer lenses (ICLs) are posterior chamber phakic lenses that provide a refractive surgery option for those with high myopia or astigmatism. The short-term and midterm results indicate good refraction stability, efficacy, and safety. Cataract has been suggested to be an important long-term complication of ICL implantation. To report the rates of cataract development and refractive outcomes 10 years after ICL implantation. The study included 133 eyes of 78 patients undergoing consecutive V4 model ICL implantations, which took place from January 1, 1998, through December 31, 2004, at Jules-Gonin Eye Hospital, Lausanne, Switzerland. Data analysis was performed from January 1, 2014, to May 31, 2014. The lenses implanted were as follows: 53 V4 model ICLs of -15.5 D or greater, 73 V4 model ICLs of less than -15.5 diopter (D), and 7 V4 model toric ICLs for myopia. Rate of cataract surgery, lens opacity, ocular hypertension, refractive safety, predictability, and stability. A total of 133 eyes of 78 patients (34 men and 44 women, with a mean [SD] age of 38.8 [9.2] years at enrollment) met the inclusion criteria. The rate of lens opacity development was 40.9% (95% CI, 32.7%-48.8%) and 54.8% (95% CI, 44.7%-63.0%) at 5 and 10 years, respectively. Phacoemulsification was performed in 5 eyes (4.9%; 95% CI, 1.0%-8.7%) and 18 eyes (18.3%; 95% CI, 10.1%-25.8%) at 5 and 10 years after ICL implantation, respectively. The vault height (distance between the posterior ICL surface and anterior lens surface) measured a mean (SD) of 426 (344) μm immediately postoperatively, decreasing to 213 (169) μm at 10 years. A smaller vault height was associated with the development of lens opacity and phacoemulsification (P = .005 and .008, respectively). The intraocular pressure was 15 mm Hg postoperatively, and there was no significant increase in intraocular pressure observed until the 10-year follow-up (16 mm Hg, P = .02). At 10 years, 12 eyes (12.9%; 95% CI, 5.6%-19.6%) had developed ocular hypertension that required topical medication. At 10 years, the mean (SD) safety index was 1.25 (0.57), with a manifest spherical equivalent of -0.5 D at 1-year postoperatively vs -0.7 D at 10 years postoperatively in eyes aimed at emmetropia. This retrospective single center study indicates that ICL implantation provides good long-term safety and stability of refraction in patients with high myopia compared with similar short-term studies. However, the rates of cataract formation and ocular hypertension at 10 years have important clinical implications, and as such this information should be part of the available patient information before ICL implantation

Neovaisseaux sous-retiniens: evolution des cicatrices de photocoagulation en l'absence de recidives. [Subretinal neovascularization: evolution of cicatrix of photocoagulation in the absence of recurrence]

Eleven patients successfully treated with the argon or krypton laser for macular subretinal neovascularization were followed up in order to determine the extent of long-term enlargement of the chorioretinal scars. The mean follow-up time was 51.5 months and the mean increase in choroidal scar size 46.5%. In 10 patients the scars enlarged more toward the fovea than toward the periphery (51% as opposed to 43%). The rate of enlargement per month decreased with time after treatment. Only one patient exhibited decreased visual acuity during the follow-up period, due to invasion of the foveola by the scar

Subretinal neovascularization secondary to choroidal septic metastasis from acute bacterial endocarditis

The clinical features of an infective embolic choroidopathy are described, from its early onset to late complications in a 45-year-old man with acute Staphylococcus aureus endocarditis of the aortic valve. Initial fundus examination revealed, in addition to fresh choroidal lesions, stigmata of a previous embolic episode secondary to endocarditis from Actinobacillus actinomycetemcomitans. The choroidal lesions were extremely asymmetrical, with a clear preference for localization in the left eye. Similar ocular findings were seen in a 78-year-old female with mitral valve prolapse and acute S. aureus endocarditis. In this case, however, choroidal involvement from septic emboli spread was bilateral and roughly symmetrical. Choroidal neovascular membranes arising in scars from choroidal septic emboli occurred in the macular area of the left eye of both patients, 10 months and 5 years after embolization, respectively

Natural history of diffuse uveal melanocytic proliferation. Case report

BACKGROUND: Diffuse uveal melanocytic proliferation is a rare paraneoplastic syndrome resulting in rapid bilateral visual loss due to proliferation of benign melanocytes within the choroid and ciliary body. Most of the previously reported cases have been seen with bilateral involvement and typical ocular features. PATIENT: The authors report the case of a 61-year-old man who presented with uniocular posterior pole lesions at the level of the retinal pigment epithelium and subsequently developed the typical bilateral lesions of diffuse uveal melanocytic proliferation. His clinical course was typical, with visual disturbance preceding signs and symptoms of malignancy by 5 months. Rapid decline ensued, and he eventually died 10 months after the onset of visual symptoms. RESULTS: Results of ocular pathologic examination showed the typical choroidal thickening due to the proliferation of melanocytes and the primary tumor was found to be an undifferentiated adenocarcinoma originating in either the pancreas or the esophagus. CONCLUSIONS: The very early funduscopic and fluorescein angiographic findings of diffuse uveal melanocytic proliferation are presented as well as the evolution, ocular pathology, and possible mechanisms for its development

Implantable contact lens for moderate to high myopia: relationship of vaulting to cataract formation.

PURPOSE: To study cataract formation in eyes with an implantable contact lens (ICL) used for moderate to high myopia. SETTING: University Eye Hospital, Lausanne, Switzerland. METHODS: An ICL (model V3 or V4, Staar Surgical AG) was implanted in 75 eyes. Three months after surgery and again at the last follow-up examination, the transparency of the crystalline lens was assessed on transilluminated photographs and the vaulting of the ICL over the crystalline lens was evaluated. Central vaulting was measured precisely on digitized photographs taken with a 75 SL Zeiss slitlamp camera, while peripheral vaulting was estimated on photographs obtained with a Scheimpflug camera. The minimum follow-up was 12 months; the mean was 21.8 months. RESULTS: At the last follow-up, 20 of the 75 eyes (27%) had an ICL-induced anterior subcapsular cataract (ASCC). The number of cataracts increased with the duration of the follow-up. Cataracts developed more commonly in older patients than in younger patients. All 20 cataracts occurred when the central vaulting was equal to or less than 0.09 mm. In 26 eyes with the same range of vaulting (among which 11 had no vaulting), the lenses were clear at the last visit. The 20 patients with cataract and the 26 patients with clear lenses matched in age and duration of follow-up but not in myopia. No touch between the ICL and the crystalline lens was encountered when the central vaulting was equal to or greater than 0.15 mm. Vaulting showed a slight decrease over time. No statistically significant difference in vaulting was found between models V3 and V4. CONCLUSION: Central and/or peripheral contact between the ICL and the crystalline lens may be responsible for the high incidence of ASCC formation in this study. Central vaulting greater than 0.09 mm appears to protect the crystalline lens from cataract formation. However, we recommend aiming for higher central vaulting (0.15 mm) to avoid contact between the ICL and the crystalline lens. This should be attainable by implanting longer ICLs
