    5 Daily startup Instruction for use 5.2 Measuring spherical corneal surfaces AT 030 5.2 Measuring spherical corneal surfaces With a spherical cornea, the applanation surface is a circle. The optical system generates two fluorescein semicircles to be coinci- denced. The measuring prism has a graduated scale. The measuring prism holder has a white and a red index line.
  • Page 31 Instruction for use 5 Daily startup AT 030 5.4 Preparing for measurement NOTE! Always anesthetize both eyes to avoid eyelid blinking. NOTE! The application of too much fluorescein solution results in readings that are too high, whereas too little fluorescein solution results in narrow semicircles, thus producing readings that are too low.
