    • Application of corneal tomography before keratorefractive procedure for laser vision correction 

      Luz, Allan [UNIFESP]; Lopes, Bernardo [UNIFESP]; Salomao, Marcela; Ambrosio, Renato [UNIFESP] (Wiley-V C H Verlag Gmbh, 2016)
      Ectasia after refractive surgery represents a major concern among refractive surgeons. Corneal abnormalities and preexisting corneal ectasia are the most important risk factors. Corneal topography and central corneal ...

    • Characterization of Rabbit Corneas Subjected to Stromal Stiffening by the Acai Extract (Euterpe oleracea) 

      Bersanetti, Patricia A. [UNIFESP]; Bueno, Tatiane L. N. [UNIFESP]; Morandim-Giannetti, Andreia de A.; Nogueira, Regina F. [UNIFESP]; Matos, Jivaldo R.; Schor, Paulo [UNIFESP] (Taylor & Francis Inc, 2017)
      Purpose: In this study, we characterized rabbit corneas subjected to corneal cross-linking (CXL) with acai extract compared with a riboflavin photo-stimulated procedure. Materials and Methods: The corneas of the slaughterhouse ...

    • Corneal Densitometry in Keratoconus 

      Lopes, Bernardo [UNIFESP]; Ramos, Isaac; Ambrosio, Renato [UNIFESP] (Lippincott Williams & Wilkins, 2014-12-01)
      Purpose: The aim of this study was to compare corneal densitometry measured by Scheimpflug tomography in normal and keratoconic eyes and to assess the differences in densitometry values among the stages of keratoconus.Methods: ...

    • Corneal infections after implantation of intracorneal ring segments 

      Hofling-Lima, A. L.; Branco, B. C.; Romano, A. C.; Campos, MQS; Moreira, H.; Miranda, D.; Kwitko, S.; Freitas, D. de; Casanova, F.; Sartori, M.; Schor, P.; Souza, L. B. (Lippincott Williams & Wilkins, 2004-08-01)
      Purpose: To report risk factors, clinical course, and outcome in patients with infectious keratitis following implantation of intracorneal ring segments (ICRS).Methods: the records of 8 patients with culture-proven infectious ...

    • Correlation between visual function and refractive, topographic, pachymetric and aberrometric data in eyes with keratoconus 

      Bilen, Neslihan Bayraktar; Hepsen, Ibrahim F.; Arce, Carlos G. [UNIFESP] (Ijo Press, 2016)
      AIM: To analyze the relationship between two visual functions and refractive, topographic, pachymetric and aberrometric indicators in eyes with keratoconus. METHODS: Corrected distance visual acuity (CDVA), and letter ...

    • Cross-linking e segmento de anel corneano intraestromal 

      Renesto, Adimara da Candelaria [UNIFESP]; Sartori, Marta [UNIFESP]; Campos, Mauro Silveira de Queiroz [UNIFESP] (Conselho Brasileiro de Oftalmologia, 2011-02-01)
      Corneal cross-linking is a procedure used for stabilizing the cornea in patients with progressive keratoconus by increasing corneal rigidity, and it is also used in corneal inflammatory melting process. The intrastromal ...
