Objective: To evaluate the efficiency of the contact lens adaptation in relation to the improvement of visual acuity in patients with keratoconus. Methods: A retrospective study of 175 patients (326 eyes) with keratoconus was carried out from March 2004 to June 2015. Data on sex, age, number of adapted eyes, keratoconus severity, and visual acuity with glasses and contact lenses were collected. Results: Of the classified eyes, 267 (81.9%) had moderate keratoconus (45 to 52D). The most frequent age group […]

Objective: Analyze clinical data, therapy and tomographic parameters of patients attended at Fundação Hilton Rocha. Methods: This essay is a retrospective study based on a random sample of 150 patients submitted to cornea tomography and previous segment (Pentacam – Oculus, Wetzlar, Germany) at Fundação Hilton Rocha in the year 2015. The patients were classified as carriers or suspects of keratoconus through the following parameters: pachymetry, anterior and posterior central elevation, Ambrosio Relational Thinnest (ART), value of D and keratometry. After […]

Objectives: To assess the demographic and behavioral profile of patients with optic medical indication of contact lenses (CL) in a public hospital in Curitiba. Methods: Cross-sectional questionnaire study of patients who attended the contact lens service of the national health system (SUS) outpatient clinic from the “Hospital de Olhos do Paraná” between September 2nd, 2014 and August 4th, 2015.

Objective: To evaluate the occurrence of a mutation in candidate genetic loci and its relation with keratoconus in patients treated in Brazil compared to healthy volunteers, through analysis of single nucleotide polymorphism in the DOCK9 gene. Methods: In this clinical study, 108 participants were evaluated, including 46 keratoconus patients and 62 healthy volunteers (controls). DNA samples were extracted from collected blood from keratoconus patients and controls. The genotyping of the single nucleotide polymorphism rs7995432 in the DOCK9 gene was determined […]

O cross-linking corneano é utilizado com o objetivo de reduzir e estabilizar a progressão das patologias ectásicas através de seus efeitos na biomecânica da córnea. Diferentes protocolos estão sendo realizados pelo mundo para expandir suas indicações, assim como seu uso em diversas faixas etárias, diferentes estágios da doença, combinações com outras técnicas, além de utilizações para doenças não ectásicas. Não há ainda um consenso nas indicações do procedimento de cross-linking, mas os resultados publicados na literatura evidenciam mudanças significativas nas […]

The corneal cross-linking has been used in order to reduce and stabilize the progression of ectatic diseases through its effects on the biomechanics of the cornea. Different protocols are being conducted worldwide to expand its indications as well as its use at different ages, different stages of the disease, combinations with other techniques, besides the utilization for non-ectatic diseases. There is still no consensus on the indications of the cross-linking procedure, but the results published in the literature show significant […]

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 […]

The intrastromal corneal ring implant surgery is becoming a surgical procedure in the treatment of keratoconus additive in order to minimize and delay the complications inherent to the pathology. Its action consists in the remodeling cornea, flattening and regulating the central corneal surface. Nowadays with the advent of new technologies, there is an important contribution in the diagnosis of keratoconus, with not only diagnosis but also more effective with better monitoring and prognosis of patients with this disorder ectatic. In […]
