    For many years, the anatomy of the medial knee corner has been reported. However, it is not exactly clear how all these structures function together. the purpose of this study is to identify and try to understand the relationship between the posteromedial corners of the knee using three-dimensional visualization techniques.This study comprises of 10 knees from adult corpses. Images were acquired from the dissection of different layers of the posteromedial compartment of the knee using a camera Nikon D40 and AF-S Nikkor 18-55 mm (Nikon Corp., Japan) placed on a slide bar. the pair of images was processed using Callipyan 3D or Anabuilder software (Ana builder, France) that transforms the two different images of the same structure with the intrapupillary distance proportion into one anaglyphic image.During knee dissection, pictures were taken and transformed into three-dimensional images that become more realistic with the use of special glasses. the images were made during the dissection of the three layers of the posteromedial compartment of the knees.Posteromedial corner ligament structures are quite complex and are not always clearly described in the literature. Three-dimensional images of these structures can help better understanding its anatomy.

    Avaliação do desempenho visual da lente intraocular difrativa multifocal - Zeiss AT Lisa 809 MTM
    (Sociedade Brasileira de Oftalmologia, 2014-04-01) Vianna, Lucas Monferrari Monteiro [UNIFESP]; Oliveira, Filipe de [UNIFESP]; Pedro, Abujamra [UNIFESP]; Jung, Liang [UNIFESP]; Brenner, Luis Felipe [UNIFESP]; Yogi, Milton [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
    Purpose:To evaluate the visual function of patients with bilateral implantation of multifocal diffractive IOL AT Lisa 809MTM by visual acuity with and without correction, contrast sensitivity curve, defocus curve and visual function questionnaire (39 VQF).Methods:Interventional clinical prospective study, which evaluated the results of 20 eyes of 10 patients who underwent phacoemulsification and IOL implantation between february and june 2012.Results:The average of residual postoperative ametropia was 0.05 ± 0.42 (-0.75 to +1.25 D) spherical diopters and -0.30 ± 0.42 (0 to -1.25 D) cylindrical diopters. In the mono and binocular defocus curve, the best visual acuity was obtained with 0.00 D of defocus (far VA). The second peak was obtained with -3.00 D (near vision at 33 cm) and among these peaks, it was observed a loss of visual performance with -2.00 D, which corresponds to intermediate vision at 50 cm. Contrast sensitivity was similar to those reported in the literature with this type of IOL, both with and without glare, and is shown in the figures. The visual function questionnaire (VFQ-39) had a mean value of 91.91 + - 6.82.Conclusion:The diffractive multifocal IOL-AT LISA 809M presented results consistent with the literature as measured by tests of visual acuity with and without optical correction, contrast sensitivity curve, defocus curve and visual function questionnaire (39 VQF).

    Comparação da função visual e do índice de qualidade de vida com uso de óculos ou de lente de contato progressiva
    (Conselho Brasileiro de Oftalmologia, 2006-06-01) Sant'anna, Neusa Vidal [UNIFESP]; Schor, Paulo [UNIFESP]; Lipener, César [UNIFESP]; Uras, Ricardo [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
    PURPOSE: To compare the visual function and the answers to a questionnaire of quality of life of patients wearing a progressive contact lens or eyeglasses. METHODS: The Focus Progressive® contact lens had been fitted in 35 patients with far visual acuity with progressive-addition eyeglasses equal to zero (log MAR) and near J1 (Jaeger). The far and near visual acuities and the measurement of contrast sensitivity were compared when the patients were wearing the eyeglasses or the contact lens and the patients' results of the scores of the quality of life questionnaire (NEI VFQ-25) were analyzed statistically considering the type of ametropy and the age. RESULTS: The far and near visual acuities and the contrast sensitivity measurement were worse with the contact lens than with eyeglasses. The answers to the questionnaire did not differ when were comparing the same patients wearing eyeglasses or contact lens, no matter the type of ametropy. The myopic and the hyperopic subgroups had worse answers to the quality of life questionnaire when corrected with the contact lens than with eyeglasses, both with age equal to or less than their median. CONCLUSIONS: The visual function was worse with the contact lens. The type of ametropy did not influence the answers to the quality of life questionnaire considering the optical correction, but age did.
