Definitions

  • the term‘functional assessment’ refers to the generation, determination and/or derivation of one or more visual acuity information to be entered into a report, the same of which will provide at least one supplementary functional component to the device.
  • the set of objective lens is configurable to move in at least two degrees of motions (XY axes), or three degrees of motions (XYZ axes) to detect and focus on the left and right eyes (or vice versa) of a human being for image capture.
  • the objective lens may be moved by the drive mechanism 304.
  • the image capturing mechanism 302 may include additional lenses or optical components for suitable image capture of the eye.
  • the tricam next moves to the right eye and calculates the refractive image of the right eye (step s216), moves closer to the right eye and captures a posterior (fundus/retina) macula centred image of the right eye (step s218), and then moves away from the right eye and captures an anterior image of the right eye (step s220).
  • a report is then generated, the format of the report may be in a pdf version (step s222).
