Objective: To analyze, in a university hospital of reference, the rate of a new penetrating corneal transplantation in patients that had previously undergone a tectonic keratoplasty and analyze the results after one year of surgery. Methods: Retrospective review of patients undergoing penetrating corneal transplantation, from november of 2010 to november of 2014. Comparative analysis of best corrected visual acuity (BCVA), intraocular pressure and corneal transparency before surgery and after one year, in the group of patients in which it was […]

Objective: To study human corneal buttons with lymphangiogenesis through histopathological examination, together with the grafts of their preceding and subsequent transplantations, evaluating the time intervals for successive surgeries Methods: A descriptive, observational and longitudinal study of human corneal buttons that have lymphatic vessels, together with its preceding and subsequent transplants. Tissues were obtained from penetrating keratoplasty in the period between the years 2006 and 2013. After a medical records review in which information on the dates of the surgeries were […]

O transplante de córnea (CT) é o tipo de transplante mais realizado no mundo e os Bancos de Olhos (BO) são organizações que capturam, evoluem, preservam, guardam e distribuem tecidos oculares. Com a evolução das técnicas cirúrgicas e equipamentos para o CT, os BOs precisaram evoluir para acompanhar estas necessidades. Esta evolução vai desde técnicas de captura de tecidos; doação de dinheiro e esclarecimento ao paciente (baseadas na internet, por exemplo); utilização de equipamentos modernos, para fornecimento mais adequado de […]

The corneal transplantation (CT) is the most commonly performed type of transplant in the world and the Eye Banks are organizations whose capture, evaluate, preserve, store and distribute ocular tissues. With the evolution of surgical techniques and equipment for CT, the BOs had to evolve to keep up with these requirements. This evolution goes from tissues capture techniques, donating money and clarification to the patient (e.g. internet-based), use of current equipment for more adequate tissues supply for the most current […]

Objetivo: O intento deste desígnio é mapear o perfil sorológico dos candidatos a doação de córneas na Irmandade Santa Casa de Misericórdia de Porto Alegre, identificando o percentual de descarte por sorologia e o marcador envolvido. Métodos: Foram analisados – retrospectivamente – os resultados da sorologia de todos os doadores de córneas compreendidos entre 01 de janeiro de 2006 a 31 de dezembro de 2012. Foram avaliados os dados de idade, sexo e os resultados da sorologia pertinentes aos marcadores […]

Objetive: The purpose of this study is to map the serological profile of candidates to corneal donation at Irmandade Santa Casa de Misericórdia de Porto Alegre, identifying the percentage of disposal by serology and the marker involved. Methods: There have been analised – retrospectively – the results of serology of all corneal donors, made between the period of 1st january 2006 and 31st december 2012. Data analised were related to age, gender and the results of serology pertinent to viral […]

Purpose: To define the epidemiological aspects of the patients submitted to keratoplasty in the state of Santa Catarina, Brazil and the main indications for this procedure. Methods: We conducted an observational, descriptive and retrospective study with the data of 1161 patients submitted to cornea transplantation from january 2008 to december 2010, at the Transplantation Center of Santa Catarina. The analyzed data were: age, gender, origin, transplant date, indication and transplanted eye. Results: The mean age was 45.51 years and men […]

Purpose: To evaluate the efficacy and reliability of a low-energy femtosecond laser with a high repetition rate for construction of deep anterior donor corneal lamellae. Methods: This was a prospective laboratory investigation. Twenty-five human corneal buttons were femtosecond laser cut to create thick anterior lamellae (diameter, 10mm; thickness, 500µm). The laser cuts were made using an LDV® femtosecond laser in a Ziemer® anterior chamber. To obtain a better edge, the lamellae were trephined with an 8mm trephine (Katena®). The central […]
