Proposal for a new approach to corneal biomechanics: dynamic corneal topography.

Author information

  • 1Medical School Ophthalmic Clinic of the Universidade de São Paulo , SP, Brazil. bonatti@uol.com.br



To establish the literature basis that could support the idea that it would be possible to analyze changes at the anterior surface of the cornea induced by an air jet applied onto the eye.


The PUBMED/MEDLINE literature basis regarding the following subjects was searched: videokeratography, high-speed photography, ocular response analyzer (ORA). The information concerning the goal of this paper was selected.


The literature showed data that support the idea of gathering 3 nowadays available technologies that could result in a new concept of 'dynamic corneal topography': the corneal topography, the air jet applied to histeresis measurement by the Ocular Response Analyzer and the high-speed photography technique used to study the tear film and the anterior surface of the cornea.


The literature basis supports the idea of gathering the existent technologies of corneal topography, the air jet of the corneal histeresis device and the high-speed photography to create a new concept in the analysis of the corneal surface: the dynamic corneal topography.
