Objetivo: Avaliar a eficácia e segurança de um laser de femtossegundo de baixa energia e alta taxa de repetição para confecção de lamelas corneanas doadoras anteriores profundas. Métodos: Este é um estudo prospectivo de investigação laboratorial. Vinte e cinco botões corneanos foram cortados com laser de femtossegundo para criar lamelas corneanas doadoras anteriores profundas (diâmetro, 10mm; espessura, 500µm). O corte a laser foi realizado com femtosecond laser LDV® na câmara anterior artificial da Ziemer®. Para obter-se uma melhor borda, as […]

The purpose of this case report is to describe a new technique to re-establish a scleral fixation of one luxated haptic, which previous suture ruptured, causing the fall of the intraocular lens into the vitreous cavity. Considering that the patient underwent two penetrant keratoplasty surgeries, there was a major concern to cause minimal intraocular manipulation and less surgical trauma. This technique consists in a closed eye procedure using the fixation lens, without exposing the haptics or using special surgical instruments. […]

OBJECTIVE: To describe the demographic-epidemiological profile and indications of keratoplasty at the University Hospital Santa Terezinha of Joaçaba (SC) from october 2006 to april 2011. METHODS: The records were obtained from the files of the Eye Center Belloto Stock of Joaçaba (SC), where the patients were accompanied before and after keratoplasty. The data analyzed were city of origin, age, gender, ethnicity and indication of keratoplasty. RESULTS: The medical records of 85 patients were analyzed, who underwent 100 keratoplasties. As to […]

OBJECTIVE: To determinate the corneal diagnoses of patients underwent Penetrating Keratoplasty (PK) in the university hospital of São José do Rio Preto, São Paulo, Brazil, and their relation to age group, gender and socioeconomic factors. METHODS: Retrospective analysis of 1085 registration forms of patients underwent Penetrating Keratoplasty in the university hospital of São José do Rio Preto, São Paulo, Brazil, from 2000 to 2009. The surgical indications were then correlated to age group, gender and socioeconomic factors, by chi-square test. […]

To describe a new method for iris fixation of intraocular lens in the absence of capsular support during penetrating keratoplasty. Its a new technique of iris fixation of intraocular lens without capsular support during penetrating keratoplasty. This technique is used in cases with a healthy iris and partial or total absence of capsular support during penetrating keratoplasty. Tied Out Open Sky is a technique easy to perform for iris fixation of intraocular lens during penetrating keratoplasty. The big advantage is […]

PURPOSE: To describe the epidemiological profile of patients waiting for penetrating keratoplasty in state of Pará, Brazil. METHODS: Transversal and retrospective study, with 1261 patients, in the period of january 2001 until to december 2009, were registered on the waiting list for corneal transplantation in the Central Notification, Captation and Distribution of Organs (CNCDO) of Pará. Registration forms of cornea receiving were used, adapted to the purposes of this research. RESULTS: In relation to frequency, it was obtained 51% male; […]

Corneal transplantation is singular because it is habitually performed on persons with visual deficiency but with preserved life expectancy, mobility and social life. A graft not well succeeded may cause real blindness and permanent misery due to pain and discomfort. One of the fundamental determinants of the success of corneal transplantation is the use of corneas of good quality. The selection of these corneas is based on three rules: innocuousness, transparency and vitality. Each one of these concepts is considered […]

The Urrets-Zavalia Syndrome presents well described ocular findings, even though its physiopathology is still unsure. Iris ischemia is the most common proposing mechanism. We describe two cases that underwent deep lamellar keratoplasty (DLK) performed by the same surgeon and developed the syndrome. In the first case, the surgical indication was for corneal opacity treatment and, in the second case, for keratoconus treatment. During the post-operatory, both patients developed fixed dilated pupil, which didn’t regress completely inspite of the onset treatment.
